Most of us consider sunglasses as a fashion accessory. But in reality, sunglasses are an essential accessory that helps to protect our eyes. Many people are aware of skin damage due to sun exposure, but they are ignorant about the fact that sun rays can damage their eyes.
So before buying sunglasses, one must know how to choose the right sunglasses because wearing wrong type of sunglasses can cause more harm than not wearing any glasses at all.
According to ophthalmologists, it is better not to wear sunglasses than to wear tinted glasses without UV protection. It is necessary to go out in the sun with clear protector that has the ability to block damaging ultraviolet light. As soon as the light is cut out, our pupil expands to let in more light into eyes. Tinted glasses that don’t have UV protection, invite trouble because they allow this harmful UV rays to enter the dilated pupil.
Choose sunglasses that not only look great but also protect your eyes. For ensuring better eye health, always wear sunglasses when you go out in the sun. Otherwise, in the long run, sun will tear up the eyes. We need to wear sunglasses that blocks UV rays hundred percent. Good sunglasses protect eyes not only from UVA, but UBV rays also which is more harmful for our eyes.
Various researches and studies show that serious visual complications can occur due to the exposure of ultraviolet light to our eyes. These include cataracts, macular degeneration, Photokeratitis or snow blindness, pterygium in which there is abnormal growth occurs on the surface of the eye, and even cancer.
A good pair of sunglasses is one that provides your eyes 100% UV protection. Though today there are contact lenses available to protect your eyes from UV rays, but they are not so effective in providing adequate protection. They should not be replaced with sunglasses. You need sunglasses to protect the whole eye area, not sparing even the eyelids.
What Should You Look For While Choosing Sunglasses?
Sunglasses are available in the market in a huge assortment of styles, range and features. It often becomes difficult to decide which pair will be best for us. But your task will be easier if you give priority to three things – it should give good eye protection, it should suit your style, and it should be comfortable to wear.
The Glasses Must Have UV Protection
As ultraviolet radiation contributes to eye disease, so the sunglasses you choose must have UV protection. The label must carry a tag that reads 100% UV protection or UV 400.
Three types of materials are commonly used to make sunglass lenses. They are polycarbonate, which is lightweight plastic but durable too, glass, which is durable but much heavier than polycarbonate, and plastic prescription grade lenses.
Sunglass Lens Coating And Tints
One of the coatings that are mostly used in sunglass lenses are UV filtering, but there are many others also. Colors are applied on these lenses so that they can absorb light when it passes through the lenses. Which color you choose is your personal choice, yet before choosing the color of your glass, you must know the significance of these colors.

For example: if you choose grey lens tints, it will reduce the brightness, but will not distort colors. Likewise, green tinted lenses help to reduce glare and also filter out the blue frequency present in sunlight, thereby creating a contrast between the way objects are observed properly. Brown and amber also reduce glare of sunlight.
Yellow lens tints though reduce the mist from blue light even better than brown tints, but color distortion is a problem with them. If you are participating in water sports or enjoying other outdoor activities, rose colored lenses will be the best choice for you as they provide a clear contrast against objects viewed in context of blue and green.
Buying sunglasses with polarizing lenses is also beneficial; because when light bounces off some objects like highways, water or any other surface, they reduce the glare instantly. Plastic and glass lenses have their own benefits. Plastic lenses get scratches easily than glass lenses. Look for scratch resistant glasses.
There are lenses available in which a thin coating is applied to make them scratch free. Avoid sunglasses that have mirror finish on outside of the lenses. Though they are popular, but they easily get scratched. You can also get photo chromatic lenses that are sun-sensitive and gets darker when they come in contact with UV radiation. Sunglasses with anti-reflective coating are also good as anti-reflective coatings helps to minimize the reflection when the light hits the lenses and bounces into your eyes.
While opting for sunglasses check for the marking CE/BS EN 1836:2005 which assures complete protection from harmful ultraviolet rays. Avoid sunglasses with weighty frames. Slender frame gives more comfort. Frames are available in plastic, titanium, aluminum and base metal and in other materials too.
Try lots of frames and get the one that feels best. Children also need sunglasses, especially on beach holidays. Don’t buy them fancy play sunglasses. Buy one that can protect their eyes from UV rays. The frame should be close fitting and can wrap around their head to prevent UV rays from entering from the sides or from the top of the frame.
Sunglass styles, just like every other fashion, changes often. But choice is so wide that no pair can go out of style. To be effective, sunglasses don’t need to be highly expensive. You just need to watch the UV rating carefully. You can develop a nice collection by choosing sunglasses with affordable prices or you can look for designer sunglasses which are bit expensive; it’s all up to you.
You can take a cue from celebrity style. A right pair can instantly add a chic, polished and fashionable look to your personality. Whichever style you may choose, do not forget to check the UV rating.
Price is not the determining factor for choosing the right pair of sunglass. Higher priced pairs are usually charged for fashion and durability, not for UV protection. You may think dark color lenses give better protection, but in reality, the clear chemical coating applied on the lens provides protection from UV rays, not the lens color.
Every time you go out in the sun wear sunglasses to protect your eyes. A good pair of sunglass will ensure better eye health.
