How much Uv Protection do you need in Sunglasses

(444 Words)
It is extremely important to wear sunglasses that provide protection from UV rays. There are a wide range of eye problems that can occur when you do not have the maximum protection from UV rays.
You should get sunglasses that block 100% of both UVA and UVB rays. This is the maximum amount. Fortunately, while you may pay a lot more for characteristics such as a designer brand or special features, you can actually find relatively inexpensive sunglasses that offer the full amount of sun protection. Likewise, just because sunglasses are expensive does not mean that they offer full sun protection. You will find many models for under $20 that offer the full UVA and UVB protection. With so many styles that offer this, do not settle for anything less.
Do not assume that just because sunglasses are dark that they provide a high amount of UVA and UVB protection. You may find extremely dark “cosmetic” glasses that offer absolutely no protection, while you can actually find completely clear glasses that offer 100% protection. Never buy a pair of dark glasses that do not offer protection from the sun because these can actually be far worse for your eyes than wearing nothing. The darkness of the glasses will cause your eyes to dilate and let more light in. Your eyes will not be protected, however, so you will essentially just be letting in more of the harmful rays. You need to make sure that you read a tag or a sticker that pronounces exactly how much UVA and UVB protection the sunglasses offer and that it is 100%.
The harmful UV rays from the sun can cause many different problems. They have been linked to a number of conditions that damage the eye, such as macular degeneration, cataracts, pingueculae and pterygia and photokeratitis, according to All About Vision. These can permanently harm your vision.
Another new consideration is the high-energy visible (HEV) radiation. Also known as “blue light,” this can contribute to macular degeneration, among other conditions. Search for eyeglasses that also address this, if possible.
There are other things to consider when purchasing UV blocking sunglasses. The larger the glasses are, the more of the harmful rays they will block. A wraparound style is the best. Also, do not forget to get your children their own sunglasses to protect them from the sun. If you have prescription glasses, then ask about the sun protection.
It is very important to get the full 100% UVA and UVB blockage for sunglasses. Once you have them, do not forget to wear them when you go out in the sun to protect you from its harmful rays.
