Coloured Contact Lenses

Sunglasses are very popular by each and every ages, even the most popular fashion brands have their own sunglasses offers… What are the prescription sunglasses?
Sunglasses work mainly as protective items and only secondly as decorations. Special vision problems prevent lots of people from being able to wear sunglasses, which makes them even more exposed to various other eye health problems. This is the case with anyone who suffers from myopia, astigmatism or hyperopia. Prescription sunglasses could be a solution for improving sight and protecting eyes from the action of the UV radiation at the same time. On the one hand the UVA rays get absorbed in the body through the eye lens, and on the other, the UVB rays cause skin burn.

Prescription sunglasses represent a combination of regular glasses with a dark lens design. There are different kinds of lenses used for prescription sunglasses, and here we can count polarized lenses, anti-reflective lenses, blue blockers, photochromic lenses and gradient lenses. It is important to mention here, before going on with the description of prescription sunglasses, that you can only order this kind of eyewear based on an ophthalmologist’s recommendation and after careful medical examination. Some health condition such as eye surgery may require total prevention of sun exposure. This is why most often doctors prescribe sunglasses with  99 or 100% protection against UVA and UVB.

Wraparound designs could be a good solution for prescription sunglasses as you’ll also be protected at the sides of the eyes too. The frame makes such protection possible, because a too thin or small frame design will be insufficient. As for the anti-reflective properties, all quality sunglasses should incorporated the polarized coating for a superior protection of the eyes. Mirror-coated lenses are sometimes used for the same purpose of reducing glare. The stage of the eye condition will also have an influence on the design of the prescription sunglasses.

It is sometimes difficult to create functional prescription sunglasses for advanced forms of myopia where the thickness of the lenses is very high. There are other situations when two or more health problems are present, as one person could suffer from both astigmatism and myopia, to give just an example. The doctor should be able to recommend an adequate course of action, with the mention that the design of highly specialized prescription sunglasses is more difficult. Very few companies can provide such designs for low prices; the more complex the prescription sunglasses, the higher the price.

You can’t put a price on your sight.  You’ve only got one pair of eyes and when they go – that’s it!If you are not able to read up close or see things as clearly as you used to, then it’s time to look at getting glasses.Prescription Glasses for reading especially should be custom-made for each individual after an eye test.A visit to the optician (ideally every two years) will deliver exactly the right prescription.  You can then use that same information to purchase prescription glasses at any outlet or on the Internet.
Cost drives many people to consider buying “ready-made” reading glasses at a pharmacy or department store. They’re certainly popular, but do depend entirely on “self diagnosis” in the store.   They are also cheap, but prescription glasses needn’t cost a fortune in the very competitive optical market nowadays.Online companies like SelectSpecs.com offer an impressive range of budget prescription glasses to suit virtually any taste.
The drawback with “off the shelf” pharmacy reading glasses is that they are basically “one-size-fits-all”.  The prescription is the same in both lenses, and the location of the optical centre of the lens is not customised as it would be prescription glasses.  Most people don’t have exactly the same prescription in both eyes, and almost everyone has a small amount of astigmatism correction in their prescriptions.  Headaches, eyestrain, and even nausea can result from wearing glasses that are too far off your actual prescription or have optical centres too far away from the centre of your pupils.
The other, more serious problem with “ready made” reading glasses is why people purchase them. If you head to the chemist rather than the doctor when you’re feeling under the weather because you “don’t want to bother the GP”, then you could be ignoring a complaint that’s more serious than you thought.   The same is true of your vision.Buying Off the Shelf means you run the risk of not spotting serious problems like Glaucoma that can be treated, but only if its caught in time.
Ready made glasses are also normally only single vision.Bifocals contain two discrete elements in the lens (top and bottom) that corrects distance and near vision problems.Varifocal lenses gradually move from one prescription to the other across the entire lens, allowing you to see clearly at all distances.   These two lens types are far better suited to most people’s lifestyle and activities, and are only available in properly dispensed prescription glasses.  Prescription sunglasses can also be made with single-vision, bifocal or varifocal designs to offer the same standard of vision enhancement and protection.Your vision is worth almost any price.  Don’t jeopardise it and insist on properly prescribed and dispensed prescription glasses.
