Many people have heard the term LASIK but do not know what it stands for. The proper interpretation is Laser-Assisted In Situ Keratomileusis The procedure reshapes the cornea which is permanent by using a laser to do the surgery. The procedure is carried out by an ophthalmologist, with the aid of sophisticated computer-controlled equipment.

How the Surgery Works. Before you decide that LASIK surgery is right for you, make sure that you know all the facts, and how they might affect you. Before committing to the surgery patients should look into what lasik is and what it can do for vision. Lasik eye surgery has been big news on the vision front. If you are contemplating LASIK eye surgery, you are not alone. This surgery can help to eliminate your need for glasses or contact lenses.

If you're like many you were just born with blurred vision, and have had to deal with the hassles of glasses or contacts for a time that is too long to remember. Although nearsightedness can be easily fixed with glasses or contact lenses (when not too severe), many people don't like to hassle with either one. LASIK laser eye surgery helps with the shaping of the cornea; once the cornea is re-shaped it will help in the reliance of wearing contacts or glasses.

Many people get the corrective surgery because they just don't want to wear glasses or contacts anymore, many people have been wearing them their whole lives.

Reading Glasses - 3 Options To Consider

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

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 can’t mess this up too bad. If you get the wrong power, they simply won’t work as well for you and your needs. But wouldn’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

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 – 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, it’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

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

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.
