Cheap Body Jewelry

2008-10-31T01:17:00.000-07:00

Body jewelry is an ancient way of expressing one's ideas, religion, and so on. But it is still popular to this day, and probably always will be. Wearing tiffany is no longer the sole pastime of a woman. Now men equally enjoy decorating themselves with beautiful tiffanys pieces.

But sometimes it is not possible for you to go for valuable and expensive jewelry made of precious metals like platinum or gold. As an alternative to the highly priced expensive body jewelry, a whole new range of jewelry has occupied the market, which is cheaply priced but looks as beautiful as the real gold or platinum jewelry. Body jewelry, better known as fashion or costume tiffany jewelry, is made of low-priced metals like silver or titanium, glass or plastic. This kind of jewelry is available with gold polish and with the use of semi precious stones like beads, diamonds, kundan etc, to give an exquisite look.

This kind of cheap body jewelry is especially targeted to the college crowd, who tend to want a cool and modern look via earrings, nose rings, naval tiffany jewellery and the like. This group, however, has limited pocket money and can’t afford expensive stuff. This kind of jewelry is also meant for middle class society, who want to be in tune with fashion and decorate themselves with trendy and charming jewelry, but whose resources are limited. So the concept of cheap body jewelry gives the freedom and opportunity for a not-so-rich class of society to decorate themselves with body jewelry.

Reading Glasses - 3 Options To Consider

2008-09-11T22:41:00.001-07:00

Are you a man or woman needing to find reading glasses for the first time and not sure how to feel about it?

You know you are still young in mind body and spirit and want to make sure the eyeglasses you choose for the occasional quick read conveys this feeling as well. Dona€?t despair; with the array of shapes, colors and materials available on the market today you should have no problem finding something to reflect your personal style.Tiffany jewery

First, what shape is the right shape? One general guideline makes it easy to narrow down your selection and find something that is not only fun but compliments your face shape. You never want to mirror the shape of your face in the shape of the frame that you choose. A round face wants an angular or oval shaped lens to offer contrast. Choosing a round shaped lens will only accentuate the roundness of circular shaped face and if this is not intentional it should be avoided.
Tiffany jewery
To keep it simple, most faces can be categorized into one of four shapes. Round, Oval, Square, or triangle. Just look in the mirror and try to decide which of these shapes your face most resembles. Don't get too involved trying to decide your face shape, just use it as a general guideline. And dona€?t get offended by the mirror if you disagree with your face shape, it is just a guideline. Then, look for eyeglasses that contrast that shape.Discount Tiffany Necklaces

Second, color, how does one choose? If you stick close to the rules offered by make up artists it is hard to go wrong. Warm skin tones should stick with warm hues like orange, copper or red. Cool skin tones should stick to cool hues like rose, purple or silver. Likewise complimentary colors can accentuate ones eye color, an amber eye surrounded in purple frames would be stunning.Discount Tiffany Necklaces

Finally, material, what makes a good reading glass? Most any material used can make a great pair of readers. In general there are two categories, plastics and metals.

Plastics are lightweight and available in a limitless variety of colors. They are often molded in the bridge area so not great for those individuals requiring a specialized fit over the nose. Metals have a tendency to be a bit heavier but are often more durable. Metal eyeglass frames are usually equipped with nosepads that are very easy to adjust for a more comfortable fit.Discount Tiffany Bracelets

Frameless options look good on most everyone and are available with both plastic or metals temples and bridges. Frameless readers are definitely the most delicate but also the most lightweight and often the most comfortable option. There are also semi-rimless lenses that have a frame that only covers a portion of the lens, usually the top or the bottom. Semi-rimless glasses are also very lightweight but offer a little more durability than a full frameless style.

Simply keeping these three considerations in mind, shape, color and material, will make your shopping process easier and help assist you in finding a pair of glasses that truly reflects who you are.Discount Tiffany Bracelets

How To Use A Reading Glasses Eye Chart

2008-09-10T19:56:00.001-07:00

Finding the right power for your reading glasses just got a whole lot easier. It used to be that people would put on any pair of readers, not paying attention to which power they need, and use their arm as an auto focuser.

Have you ever noticed someone at the restaurant struggling to see the menu? They pull out a pair of glasses to ease their eyes. But two seconds later, grab the candle to help them see even better. Then move their arm back and forth as an auto focuser. This person is not wearing the proper correction in their reading glasses.

So how do you avoid this situation? Simple, understand how readers work and what power you need to see that menu. The first thing to understand is that higher power readers work great to magnify the little print. However, the higher the power in your readers, the less range of focus you will have.

The second thing to understand is the role that lighting plays in your vision. Good lighting can mean the difference between a +1.50 and a +2.00. What does this mean for you? If you have a good lamp at your side when reading the paper, a +1.50 will allow you to scan the entire paper better. However, if your lighting is dim you may need a +2.00 reader. A little tip for all you reading glass wearers: If you carry a pair with you to go the restaurants or shopping, get a power slightly stronger than you normally wear. This will allow you to see those tiny price tags, read ingredient labels, and see that menu.

One other thing to understand about reading glasses is that they are completely safe for your eyes and you really canâ€™t mess this up too bad. If you get the wrong power, they simply wonâ€™t work as well for you and your needs. But wouldnâ€™t it be wiser to get the right lens correction to begin with?

Reading glasses come in plus powers. They will range from +1.00 to +3.00, pronounced plus one. A +1.50 is pronounced as plus one fifty, and so on. A lower number depicts a lower the magnification and of course the higher the number, the greater the magnification.

The easiest way to figure the exact power you should be wearing is view a near vision eye chart. Eye charts are widely available online, one can be found at http://www.readinstyle.com this eye chart has text of a specific size. Simply hold the chart at your comfortable reading distance. Looking at the text, which is the smallest line you can see clearly? To the side of that text will be a reading glass power. That is all there is to it. That power is the power you should have in your reading correction.

Get The Most From Your Hand Held Magnifying Lens

2008-09-09T02:11:00.000-07:00

It is common for jewelers, craftsmen and quality controllers to use magnifying glasses to enlarge the appearance of an object they are analyzing. At the home, people with near vision difficulties are able to enhance their vision with a magnifier. With this, the text on a page will seem larger, and therefore easier to read.

While magnifiers function well, handheld magnifier lights are useful to project adequate light onto an object for greater clarity. In fact, with more light used, it is possible to use a lower magnification power and thus work on a wider field of vision. This occurs as the field of vision of a magnifier decreases as magnification power increases.

Handheld magnifier lights are great as they are small and portable. This means they can be taken along and used whenever needed. Apart from that, they are fitted with bulbs that project the right amounts of light with minimal shadowing. While non-portable desktop or standing magnifying lamps usually use 22 watt incandescent lamps for lighting, these are too large for their handheld cousins.

As an alternative, bright LED lights are used for these magnifiers that are usually powered by AA or AAA size batteries. In order to conserve energy, they can be turned off and on and only used to illuminate objects in low light condition, or when lower magnification power is used.

While LED handheld magnifier lights cost less than $20 each, a more expensive version â€“ Xenon handheld magnifying glass, costs between $60 and $100. These lights are extra bright and are great when extra lighting is needed for work.

When using handheld magnifier lights, itâ€™s best to hold the magnifier as close to your eye as possible. Then turn on the light and slowly bring the object from a distance towards your eye until it comes into focus. With this, you will be able to maximize the view and at the same time reduce image distortions.

Why Home Pure Water Systems Are So Important to Your Health

2008-08-21T02:48:00.001-07:00

Home pure water systems have become all the rage! And it's no wonder! With all of the negative press our municipal water systems have had lately, who doesn't recognize the need to filter their own tap water. Turns out bottled water is not much better than tap water, if any. In other words, having your own home pure water system is no longer an luxury. It's now a necessity.

The only question is which type of the many pure water systems available should you buy? There are a number of ways to purify and filter water. Among them are distillation, reverse osmosis, exposure to ultraviolet light, and carbon and ceramic filtration. All of these have their strengths and weaknesses.

Although distillation is a very common pure water system, it has two faults. For one thing, it's expensive. For another you have to be careful about distilling chlorinated water. (Distillers work by heating up the water. The chlorine that's already in your water can create carcinogenic compounds with organic materials, which then will be vaporized by the distiller. This means they'll end up in the supposedly pure water.)

Reverse osmosis was the water purification system of choice. There are some issues with it as well. Reverse osmosis is not nearly as expensive as distillation. So, money is not the issue. It's the fact that it "demineralizes" the water.

The water that we are supposed to drink has naturally occurring minerals in it. Although the amounts vary, in pure, natural water you'll find trace amounts of minerals like potassium, calcium, and magnesium. Our bodies need these trace minerals in order to function properly. Because of the way it works, reverse osmosis takes these minerals out. Some scientists actually think there are long term consequences to drinking demineralized water.

Ultraviolet radiation (UV) is also a very common technology used to create pure water systems. UV works great, by the way. It's only effective on living organisms--bacteria, viruses, and microorganisms. It will do nothing to get rid of the whole host of other stuff in your water like lead, pesticides, and prescription drugs.

Perhaps the best all around water filtration technology uses carbon and/or ceramic filters. Usually these are used in a two-step process where you filter out the organic contaminants first, then the inorganic impurities next. This way you can make the water pure, but leave in the trace minerals. This type of pure water system is also substantially cheaper than many of these other methods.

High Index Eyeglass Lenses

2008-08-07T20:22:00.000-07:00

As anybody who has had to wear thick lenses can tell you, it can make you a little self-conscious and you would do anything for something a little thinner. Lenses are made from a variety of materials. Many of these materials are designed to be thinner than a conventional lens. This means that they have a higher Index of refraction. Index of Refraction refers to the lenses ability to bend light. The prescription of a lens is determined by two main factors; the lens?s index of refraction and lens curvature. The higher the index the less curvature that is needed thus the lens can be processed thinner. The lower the index the more curvature is needed for the desired prescription thus making it thicker.

Often you may hear the Optician or doctor referring to these lenses by numbers such as such as 1.60, 1.66, and 1.70. These numbers represent the refractive power of the lens. The higher the number the thinner the lens. There are several other benefits to a high index lens. Lenses with a higher index often have a greater tensile strength than other conventional materials. This tensile strength is around 15,000 psi! This makes them suitable for drill mount glasses.

But because a lens is thinner and tougher does not mean that it is without flaws. The higher the index the more reflection that occurs off of the lens surface. The higher the index the more resistance is given to light. This resistance increases the amount of light that is bounces off. For instance a conventional plastic lens with an index of 1.498 will cause 8% of the light to reflect off of the surfaces creating 92% transmission. A lens with the index of 1.70 will cause 13.6% of the light to be reflected creating only 86.4% transmission. The application of an Anti-reflective coating can greatly increase light transmission.

Chromatic Aberration

Another aspect of these lenses that wearers often find annoying is a phenomenon called Chromatic aberration. Looking through a lens with a high index you may notice that there is a color hue around certain images. The further you move from the center of the lens the more noticeable it becomes. High index lenses have a very high ability to create dispersion. When white light passes through one of these lenses it begins to break up into its component colors. This can be minimized by choosing a frame that is smaller and allows the eye to center well within it. It often takes no longer than a day or so to fully adapt.

Depending on your needs a high index lens may be ideal for you. They are cosmetically appealing and are available in many lens designs including Progressive lenses. Proper frame selection and a thin lens can drastically improve appearances.

Watch and Jewelry Industry Remember Ben Kasiser

2008-07-23T00:59:00.000-07:00

In an unusual summer event, scores of watch, jewelry, and retail industry leaders gathered July 26 in New York City for a luncheon honoring the late Benjamin Kaiser, a watch and jewelry industry leader himself active in many trade organizations for almost a half-century, on the 10th anniversary of his death.

The event was held in the historic Lotos Club, where Kaiser for years held celebrated parties for the industry preceding the annual Twenty Four Karat Club of New York dinner.

Kaiser fought in the Polish underground during World War II and later became a U.S. citizen. He founded New York-based David G. Steven, Inc., U.S. distributor of Swiss luxury watch brand Baume & Mercier, and was later president and chairman of Baume & Mercier USA (after acquisition by the brand).

One after another, various trade and association leaders at the well-attended luncheon rose at their tables to offer their memories of Ben Kasier and speak of his wit, wisdom, ethics, business acumen, Old World charm, friendship, and support of the industry.

The luncheon was co-hosted by Rudy Chavez, current president of Baume & Mercier USA, who praised Kaiser’s dedication as a businessman to “integrity, community, and customer service” and his son Steven Kaiser, president of Kaiser Time, who recalled his father’s devotion to his adopted country and toasted him as “a great man.”

Stronger Warnings For Lasik Surgery From FDA

2008-07-16T22:40:00.000-07:00

Lasik Surgery (laser-assisted in situ keratomileusis) is the most advanced eye surgery. According to Golfer Tiger Woods "It is a life changing". NASA is now allowing astronauts to undergo this procedure, and in the U.S. military, nearly 112,500 personnel, have undergone this surgery, including pilots.

But FDA (U.S. Food and Drug Administration's) Ophthalmic Devices Panel convened Friday to discuss post-LASIK quality-of-life issues. At the end of the day FDA warn more clearly about the risk and post complications of the Lasik Surgery.

On hearing this problem Dr Christopher Starr says, "This is ground-breaking news. It's the first time anything like this has happened around refractory, or LASIK, eye surgery. I think this surgery is the best , because I know that the surgery, when done on the right patients, is a great, great surgery with phenomenally good outcomes." According to the Lasik Surgery task force, formed in 2007, 95.4% of patients were satisfied. This task force was conducted by FDA, The American Academy of Ophthalmology, and the U.S. National Eye Institute.

But FDA is revealing latest news, that among 7.6 million people who have undergone this procedure in the United States in the mid 1990's, 140 have written complaint to the FDA. Now FDA is following up the complaints, and the Friday's hearing was a part of the large review to see if new warnings about the Lasik Surgery are needed to alert the consumers to the possibility of the eye pain, dry eyes, blurred or double vision, and other problems.

Some of the affected patients were present on Friday, and they complaint that their vision is not cured rather they have poor night vision, some have glare or halos, some complained of dry eye "The FDA has called it as quality-of-life-issue". said Dr. Robert Cykiert, associate professor of ophthalmology at New York University Langone Medical Center.

"Too many Americans have been harmed by this procedure, and it's about time this message was heard," said David Shell of Washington, D.C., who had the surgery in 1998 and said he has "not experienced a moment of crisp, good quality vision since".

LASIK surgery involves cutting a small flap in the eye's cornea using a laser. With the flap held out of the way, the surgeon can then reshape the corneal tissue with another laser. The procedure can be used for nearsightedness (as in Tiger Woods' case), farsightedness and, in some cases, astigmatism.

But the much-touted procedure is not for everyone. Those who have a misshapen cornea or excessively thin cornea, who have early cataract formation or big pupils, who have dry eyes, or underlying conditions such as lupus or rheumatoid arthritis, should be ruled out,"said Dr. Norman Saffra, director of ophthalmology at Maimonides Medical Center in New York City.

Presby-LASIK Cures Hyperopia

2008-07-15T19:26:00.000-07:00

Bruce W. Jackson, MD, and colleagues has performed presby-LASIK on 28 hyperopic patients and observed that it results in good near and distant vision.

Surgery involved applying bilateral aspheric ablations to treat patients' presbyopia. Surgeons then performed a CustomVue (Advanced Medical Optics) hyperopic treatment with a central presbyopic ablation, creating a central near vision ablation profile, Dr. Jackson said.

At 6 months, 86% of patients had 20/20 binocular distance uncorrected visual acuity, and all patients had 20/40, Dr. Jackson said. For uncorrected near visual acuity, 90% achieved J1 and all patients achieved J3, which was the target vision. Overall, patients were satisfied with their outcomes, he noted.

"We think this procedure is a good alternative for young presbyopes with low refractive error, especially those who don't want intraocular surgery," he said.

Wedding ring sets United we stand

2008-07-14T18:57:00.000-07:00

Wedding ring sets are integration of both engagement and wedding ring in a
similar design, complimenting one another. It is suitable for women who hate
wearing more than one ring, or for couples who have budget constraints. It
is actually called wedding set and is designed to be worn together, and
these rings cannot be worn separately as they are soldered to be worn
together for a seamless and permanent fit, hence they are inseparable.

tiffany jewellery of Wedding ring sets symbolizes the deep and intertwined relationship they
share without discriminating each other and giving each other the same
status in the society. The wedding set is a perfect complement to a romantic
relationship; many couples choose rings set which symbolizes their closeness
and togetherness in harmony and passion with matching designs and settings.

A united wedding ring set is an elaborate designed pair; the pair should
have a co-ordination wrap to each of the ring. Yellow gold is the most
commonly used in the wedding ring set, but one can also use the combination
of yellow as well as white gold to give a striking look to the wedding ring
set. Wedding ring sets are mostly designed with intricacy and delicate
detailing since they are surrounded with multiple small stones in a pattern
with a large stone in centre.

OTC Reading Glasses may not help astigmatic vision

2008-07-13T19:29:00.000-07:00

Now many of us out there have an astigmatism. It's a condition in which the cornea or the crystalline lens is football shaped rather than spherical. OTC Readers do not correct for this. If your astigmatic correction is not very strong, you may get along with these readers just fine. However if it is rather significant such as a 1.00 or above you may experience some difficulty.

There are those out there that have certain conditions in which the eye begins to wander or there may be other ocular motor dysfunctions which can be corrected with the use of prisms. The prismatic effect is experienced any time one looks away from the Optical center of the lens. In the case of prescribed prism the doctor has determined that the optical center should be moved either up, down, in or out or any combination of these. OTC Readers do not account for this.

Fighting Macular Degeneration with Antioxidants

2008-07-10T23:49:00.001-07:00

Research shows that antioxidants may lower the incidence of age-related macular degeneration (AMD) or at least slow the progression of the disease:

* Vitamin E was associated with a 13% reduced risk of AMD in a 12-year study of 22,000 male physicians.

* A study of patients with signs of AMD showed those who took zinc supplements had less visual loss from the disease compared to patients receiving a placebo.2

* In 1994, the Eye Disease Case Control Study indicated that dietary carotenoids, particularly lutein and zeaxanthin, slowed the progression of AMD. People who ate the most green leafy vegetables were 88 percent less likely to develop severe AMD than subjects who ate the least amount of green leafy vegetables.

Macular degeneration (MD)

2008-07-09T20:31:00.000-07:00

This is the leading cause of irreversible blindness among Americans over 65! The macula is a portion of the retina in the back of the eye. MD occurs when macular cells in the center of the retina become damaged. This is caused in part, by oxidative damage. The retina is particularly susceptible to such damage, because it is exposed to more oxygen than any other organ in the body, except for your skin. Furthermore, the retina contains a high concentration of lipids, easily damaged by oxygen.

Cosmetics A secret of perpetual beauty

2008-07-09T00:48:00.001-07:00

Cosmetics have been admired by women all over the world since it was first created in France thousands of years ago. The definitions of looking good differ a lot in different cultures. For example, western world prefers wildness rather than gentleness which is in contract generally appreciated by eastern people. But the pursuit of beauty is uniform and degree by degree becomes a thematic matter that women all over the world are engaged in. Cosmetics are to women what food is to human beings. Cosmetics are playing significant roles in almost every woman's life despite the fact that people belonging to different cultures have different ways of keeping themselves young, attractive and charming. For instance, Indians do yoga while Americans go to palaestra regularly to keep fit and healthy. Those who have never used cosmetics for the sake of destitution may doubt its practicality. However, the truth is these women may surprisingly realize that they are actually much prettier than ever when they put on the make-ups for the first time, and later find it horrible to imagine a life without cosmetics. The Five basic cosmetics are requisite for a beginner Women use cosmetics to give prominence to their facial features and make up for the visual deficiencies of the five sense organs so as to make their countenances pleasing. But to master the skills of making up a perfect face is anything but easy. For a beginner, the following five cosmetics are enough and necessary to purchase---- a tube of make up base, a powder pact, an eye pencil, a mascara and a lip stick. With the make- up base well daubed onto your face, you can make your complexion homogeneous. Then you apply the powder to make yourself fairer. The eye pencil can not only darken your eyebrows but is also used to draw the outline of your eyes as well as to make your orbits stand out. To finally make a pair of eyes full of spirit, you need the requisite mascara to elongate your eye lashes. However, the applying of the former four cosmetics altogether promises you a purely pale face, which might be a little bit unnatural. Fortunately, you do not need to worry at all, because the lip stick will come to rescue. As soon as your lip is applied with lip gloss, your face will be as florid as a blossoming flower. Cosmetics at Madeinchina.com are safe and less expensive Being perfect for a beginner, these five basic cosmetics are available at madeinchina.com, which is just like a trustworthy consultant you can always turn to for advice.

Does LASIK Improves Patients Lives?

2008-07-07T19:00:00.000-07:00

he U.S. Food and Drug Administration (FDA) plans to review whether LASIK, laser eye surgery, is really improving patients lives. FDA says that the move is in response to a number of concerns raised about patient satisfaction with the procedure.

Complications that patients can experience from LASIK include dry eyes, glare, double vision, an increased risk of inflammation or infection in the cornea, and rarely blindness.

An FDA advisory panel will hold a public meeting that will focus on patients' quality of life after surgery.

Dry Eye In Shih Tzus

2008-07-06T20:18:00.001-07:00

Among other breeds of dog, Shih Tzus and Pugs are more likely to obtain keratoconjunctivitis. Keratoconjunctivitis is a Latin word which literally means dryness of the cornea and conjunctiva. It is commonly known as dry eye.

This disease is the result of abnormal production of tears. Tears are essential because it cleanse and lubricate the cornea, carry the nutrients and also help in healing and control of the infection.

KCS is thought to be caused by some viral infections like canine distemper as well as immune mediated diseases. Other reasons of this disease are hyperthyroidism and the use of sulfa-containing drugs. Sulfa-containing drugs cause dry eyes by producing a toxic effect and the absence of this drug may improve dry eye.

Dry eye in dogs is characterized with dull and dry winking eyes. He may also experience recurrent eye infections and/or corneal ulcers. Thick, green discharge is usually seen sticking to the hair around the eye. This is usually diagnosed in one eye first and later develops in the other eye within several months. A dog with KCS tends to squint and rub his eyes and is sensitive to light. If your dog is showing any of these symptoms, it is best to see your veterinarian immediately for eye examination.

Dry eye is diagnosed based on the symptoms mentioned earlier. Also with a Schirmer tear test (STT) that measures the production of the tear production in the eye. A dog’s normal STT values are 15 to 25 mm/minute. Dog breed that is susceptible to conjunctivitis, even without clinical signs of dry eye should undergo STT.

Treatment of KCS usually aims to restore the moisture of the eye by lubricating the eye, tear replacement, stimulating tear production, reducing bacteria overgrowth and reducing inflammation. Substitutes like polyvinyl alcohol, methylcellulose and hyaluronic acid are traditionally used to replace the lost tears. However, these solutions do not have a primary effect on the inflammation process and in the production of tears.

Recently veterinarians prescribe Cyclosporine, diluted in water and applied to the surface of the eye in order to stimulate tear production. Cyclosporine shows no undesirable effects even if used in long term basis. The use of cyclosporine may retain a dog’s vision for years but that doesn’t work for all patients with KCS. These treatments do not cure KCS, but are just ways to deal with this painful condition. In worst cases, dry eye can also be treated through surgery.

Dry eye seems to be a simple disease but if left untreated, might damage your dog’s vision or may even result to complete blindness.

Laser-Assisted In Situ Keratomileusis

2008-07-03T23:36:00.000-07:00

LASIK (Laser-Assisted In Situ Keratomileusis)

This laser procedure involves creating a thin flap on the cornea (with a laser or a microkeratome) and reshaping the underlying corneal tissue with a laser.

PRK (Photorefractive Keratectomy)

This laser procedure is similar to LASIK, but the laser treatment is performed on the surface of the cornea, not under a corneal flap.

LASEK (Laser Epithelial Keratomileusis)

Epi-LASIK

LASEK is a laser procedure that can be considered something between LASIK and PRK. A corneal flap is created in LASEK, but it is significantly thinner than a LASIK flap and consists of only the top layer of corneal cells (called the epithelium). LASEK is also called Epi-LASIK.

Laser Vision Correction and Reading Glasses

2008-07-03T01:25:00.000-07:00

Laser vision correction means you'll be able to drive and see TV without your glasses. But if you are over 40 years old, what about your reading vision?

Patients with good distance vision invariably become gradually more dependent on reading glasses around their mid forties. However if you are myopic (near sighted), you can read well without glasses, indeed you'll probably find yourself taking them off.

I often hear people tell me, "You mean I will still need glasses after the laser treatment, but now for reading? So what's the point?"

It does of course depend on the individual. For a taxi driver who just wants to be able to drive without glasses this is not a problem. But for a bank clerk who spends his entire day reading papers, suddenly requiring reading glasses for the first time will not be a welcome result after his laser treatment.

The solution to this problem is called Monovision. In Monovision we deliberately undercorrect one eye, the non-dominant eye, leaving it slightly myopic (near sighted), usually about -1.0 to -1.5. In this situation one eye, the fully corrected one, sees well for distance, and the other undercorrected eye sees well for near/reading.

In my experience about 75% of patients adapt well to this slight imbalance between the two eyes and no longer require glasses for distance or reading or any other daily activity. Pre-operative testing and counseling can select the best cases.

Farsighted candidates can also be helped with this technique although in their case they require an overcorrection (excess laser treatment) on one eye to make that eye deliberately slightly near sighted. Satisfaction in this group of patients is somewhat more difficult, but as far sighted people don`t see well either for near or for far, just giving them good distance vision is tremendously satisfying.

Things You Should Know Before Your Trip to Beijing

2008-07-01T23:47:00.000-07:00

Ask the most seasoned traveler to share his or her experiences or to discuss some of the most spectacular places he or she has been, and Beijing is likely to be at the head of the list. Not only is Beijing rich in culture, it is certainly one of the most unique places in the world for a traveler to visit. In fact, all you have to do is take a look at some interesting facts about Beijing and you will want to see it for yourself.

The Center of It All

Did you know that Beijing is the center of China's political and educational establishments? You will find that the city is also the cultural cornerstone of China, which is why you can submerge yourself so deeply in the culture when you visit the area. Whether you want to get a peak at the every day lifestyle or if you want to get a better feel for China's political system, Beijing is a good place to start.

Getting Money From an ATM

The money used in Beijing is the RMB, which is called 'Kuai' in Beijing. The exchange rate for the U.S. Dollar is 8 Kuai per 1 US dollar, so the prices you see on goods in Beijing will appear to be more costly than you thought. You might also be surprised to find that you can use your foreign credit cards in many of Beijing ATM machines. Still, you should be prepared for the possibility of not being able to use your card when you visit.

For the best chance of using an ATM card, keep your eye out for a Bank of China ATM, as these ATMs are more likely to accept your card than any other. There are ATM machines located throughout Beijing and you should not have a problem finding a machine that will work for you. If you try to withdraw money from a Bank of China ATM and you are unsuccessful, you might want to try again. Although the country is known for its technology, the ability to connect to an international line is sometimes unavailable. As a result, you may receive a declined transaction the first time around.

Haggle for a Great Deal

When shopping in Beijing, you should also remember to haggle over the price of pretty much everything available from local merchants. Merchants in Beijing expect their shoppers to haggle over the price and getting involved in a price debate is a great way to really experience the Beijing culture. Of course, it can also help you get a cheaper price. Understanding this cultural difference of opinion is something you should think of as an event rather than an argument of price.

Beyond the price of goods, you should also be aware that there are counterfeit goods readily available in China. If you want to be sure you are getting the designer purse, hat or eyeglasses you wanted, you need to use extreme care. Otherwise, you might get a lot less than you expected. Still, whether you are looking for designer brands or not, you will be amazed by the multitude of offerings and the number of individual shops and vendors lining the streets in Beijing.

Finding the Facilities

After a day of shopping, you will likely find yourself needing to use the restroom. Have no fear! Finding public facilities in Beijing is relatively simply and the toilets are generally kept quite clean. Keep in mind that the English symbol for rest room is WC, so keep your eye out for this symbol when looking for a place to go to the bathroom. You can generally find a free bathroom to use in restaurants, supermarkets, Internet bars, and most public locations. If you find you need to use one of the moveable versions along the road, however, expect to be charged a small fee for the convenience.

The Night Life

With a day of shopping at the market behind you, you might now be ready to look into what Beijing has to offer at night. Disco is still king in China. Therefore, in Beijing, you can find the type of disco atmosphere you're looking for if you are ready to dance. Here, you will find every type of Beijing resident relaxing and having a good time. The crowd will likely be a mix of party lovers and friends who come to dance and enjoy the evening.

To find some of the best nightlife in Beijing, you'll want to look for a place called Banana Spicy for a great night of disco. If disco isn't your thing, and you want to see another aspect of Beijing's nightlife activities, grab a Chinese friend and go Karaoke. Though you won't find many English songs to choose from, this is entertainment in its purest form. Watching the Beijing residents who come and explode their voices to tunes that you cannot understand, is a lot of fun while also showing you that Beijing is a lot like home.

What Lasik Vision Correction Surgery Is

2008-06-30T18:18:00.000-07:00

What Lasik Vision Correction Surgery Is

Millions of people have been able to discard their eyeglasses or contact lenses after undergoing a Lasik laser vision correction surgery. But even though many people are aware that Lasik laser vision correction is a surgical procedure that employs a laser to improve eye sight, they are often unfamiliar with the details.

So, what exactly happens during the vision correction surgery done by a laser? Laser Assisted In Situ Keratomileusis (LASIK) can free corrective lens wearers from their dependence on contacts and glasses. Vision problems that include nearsightedness, farsightedness, and astigmatism can be corrected with this procedure.

LASIK utilizes a cold beam laser to reshape the corneal area as necessary in each patient in order to correct vision problems caused by imperfect corneas. Flaws in the shape of the cornea are responsible for these kinds of refractive errors. The Lasik laser procedure corrects the imperfections through reshaping the eye, allowing for clear vision.

This is done by making a small cut at the front of the eye to allow the laser to reach the area to be smoothed out. The surgeon cuts the flap using either a laser or a microkeratorne, which is a knife-like instrument. A small portion of tissue from the front of the eye is cut into a hinged-flap.

After the flap has been cut, the Lasik laser can access the cornea and begin repairing its shape, changing it into a correctly shaped cornea with normal function. Once the cornea has been reshaped, the flap is returned to its normal position and the surgery is pretty much completed.

Although adjustments made to the cornea's shape are permanent, other Lasik vision correction measures can usually be made if necessary. While patients considering Lasik vision correction surgery should focus on the benefits of the procedure, they also need to understand that there is always the possibility of risks and side effects.

This procedure is fast, normally pain free, and has few side effects or possible risks. Each eye takes less than a few minutes when the Lasik laser is used on it for vision correction surgery. Most often patients complain that their vision is hazy but this problem usually disappears within a few days.

Prior to the procedure, all candidates for Lasik laser vision correction are guided through the process and gain knowledge of the options, risks, and long-term benefits. Still needing to wear corrective lenses is the most common risk after the surgery has been completed.

A Lasik laser vision correction candidate should consult with his/her eye care professional who will be able to assist the person in making an informed decision with regard to the procedure. Patients will be more at ease with their decision if, in addition to knowing that the procedure will help them see better, they understand what Lasik is and how it works.

ALTERNATIVE TO LASIK FOR VISION CORRECTION

2008-06-30T01:54:00.000-07:00

According to the meshwork programme inform , after reports of defeated preoperative outcome of Lasik Surgery and ensuant warnings presented by bureau on LASIK surgery, whatever patients are fearing and indecisive to participate LASIK surgery for the communication of eye disease. Realizing that, whatever of the Optometrists of America, are considering of added alternatives that has been invented to form cornea of the eye.

“Vision rebuke surgery crapper be a enthusiastic choice for whatever patients, and jillions of grouping are mitigated with the results,” said Dr. Craig Hoeft, OD, of the Calif. Optometric Association. “But for those who are afraid and poverty to move until the bureau has more findings most Lasik and Vision ICL, a newer preoperative option, there are individual nonsurgical options that wage momentous results and are easy, easy and innocuous for many, whatever patients.”

Silicone hydrogel fleecy occurrence lense is digit of the field deciding to LASIK surgery. These lenses are caretaker semipermeable and crapper be attrited for 30 serial life without removal.

Another deciding is Corneal reshaping technology. This is also a non preoperative procedure. It reshapes the cornea daylong with specially fashioned pedal semipermeable therapeutic occurrence lenses that are inserted into the receptor before feat to bottom and distant in the morning.

There is still added deciding - unadaptable pedal semipermeable lenses (GP) or pedal semipermeable occurrence lenses. These are unadaptable lenses prefabricated of firm, imperishable impressible that transmits pedal into the eye. GP occurrence lenses are rigid, but they shouldn’t be potty with old-style “hard” occurrence lenses, which are today obsolete. GPs transfer more pedal to the receptor than do tralatitious fleecy occurrence lenses (although whatever newer polymer hydrogel fleecy lenses are same to GPs in pedal transmission).

Gas semipermeable occurrence lenses crapper also wage meliorate vision, durability, and installation status than fleecy occurrence lenses. They crapper be easier to clean, and since they’re long-lasting, they crapper be inferior pricey in the daylong constituent than fleecy lenses.

What is LASIK?

2008-05-15T19:39:00.000-07:00

The eye and vision errors
The parts of the eye. Indicated are the conjunctiva, sclera, choroid, optic nerve, retina, chamber angle, lens, cilary body, vitreous humor, aqueous humor, iris, pupil, cornea. The cornea is a part of the eye that helps focus light to create an image on the retina. It works in much the same way that the lens of a camera focuses light to create an image on film. The bending and focusing of light is also known as refraction. Usually the shape of the cornea and the eye are not perfect and the image on the retina is out-of-focus (blurred) or distorted. These imperfections in the focusing power of the eye are called refractive errors. There are three primary types of refractive errors: myopia, hyperopia and astigmatism. Persons with myopia, or nearsightedness, have more difficulty seeing distant objects as clearly as near objects. Persons with hyperopia, or farsightedness, have more difficulty seeing near objects as clearly as distant objects. Astigmatism is a distortion of the image on the retina caused by irregularities in the cornea or lens of the eye. Combinations of myopia and astigmatism or hyperopia and astigmatism are common. Glasses or contact lenses are designed to compensate for the eye's imperfections. Surgical procedures aimed at improving the focusing power of the eye are called refractive surgery. In LASIK surgery, precise and controlled removal of corneal tissue by a special laser reshapes the cornea changing its focusing power.

(See the animation of the LASIK procedure and what should I expect before, during, and after surgery.)

Other types of refractive surgery
Radial Keratotomy or RK and Photorefractive Keratectomy or PRK are other refractive surgeries used to reshape the cornea. In RK, a very sharp knife is used to cut slits in the cornea changing its shape. PRK was the first surgical procedure developed to reshape the cornea, by sculpting, using a laser. Later, LASIK was developed. The same type of laser is used for LASIK and PRK. Often the exact same laser is used for the two types of surgery. The major difference between the two surgeries is the way that the stroma, the middle layer of the cornea, is exposed before it is vaporized with the laser. In PRK, the top layer of the cornea, called the epithelium, is scraped away to expose the stromal layer underneath. In LASIK, a flap is cut in the stromal layer and the flap is folded back.

Another type of refractive surgery is thermokeratoplasty in which heat is used to reshape the cornea. The source of the heat can be a laser, but it is a different kind of laser than is used for LASIK and PRK. Other refractive devices include corneal ring segments that are inserted into the stroma and special contact lenses that temporarily reshape the cornea (orthokeratology).

What the FDA regulates
In the United States, the Food and Drug Administration (FDA) regulates the sale of medical devices such as the lasers used for LASIK. Before a medical device can be legally sold in the U.S., the person or company that wants to sell the device must seek approval from the FDA. To gain approval, they must present evidence that the device is reasonably safe and effective for a particular use, the "indication." Once the FDA has approved a medical device, a doctor may decide to use that device for other indications if the doctor feels it is in the best interest of a patient. The use of an approved device for other than its FDA-approved indication is called "off-label use." The FDA does not regulate off-label use or the practice of medicine.

The FDA does not have the authority to:

* Regulate a doctor's practice. In other words, FDA does not tell doctors what to do when running their business or what they can or cannot tell their patients.
* Set the amount a doctor can charge for LASIK eye surgery.
* "Insist" the patient information booklet from the laser manufacturer be provided to the potential patient.
* Make recommendations for individual doctors, clinics, or eye centers. FDA does not maintain nor have access to any such list of doctors performing LASIK eye surgery.
* Conduct or provide a rating system on any medical device it regulates.

The first refractive laser systems approved by FDA were excimer lasers for use in PRK to treat myopia and later to treat astigmatism. However, doctors began using these lasers for LASIK (not just PRK), and to treat other refractive errors (not just myopia). Over the last several years, LASIK has become the main surgery doctors use to treat myopia in the United States. More recently, some laser manufacturers have gained FDA approval for laser systems for LASIK to treat myopia, hyperopia and astigmatism and for PRK to treat hyperopia and astigmatism.
