LASIK Facts

Everyone should protect their eyes from the harmful rays of the sun by wearing fashion sunglasses. Wearing ones that block out the ultraviolet A and B rays plus HEV rays are the best ones that you can get for your eyes. You will be protecting your eyes from possible cataracts, and the skin around your eyes from possible skin cancer.

Dark glasses are not only for fashion. They are not made to keep you from squinting when you drive or when you are outside. Glasses with lenses that block the sun from your eyes are made for your protection.

When you leave your eyes unprotected for even a brief amount of time you risk getting them sunburned. This is often painful and gives you a feeling of having dirt in them. This will not cause permanent damage to your eyes. Not having any glasses that block out the suns' rays over a long time period can be permanently damaging. People must be made aware of the damage that can occur to their eyes when left unprotected.

Studies have proved that long-term exposure to UVA will lead to cataracts and damage to the retina. UVB rays do not have as much energy as UVA ones do, but if overexposure can give you skin cancer in the eye area. Being exposed to UVB rays for a shorter length of time will cause the corneas to become inflamed. This has the effect of short term blindness lasting over twenty four hours.

Eighty percent of exposure to the sun occurs when people are younger than age 18. Children are known to spend more time outside than adults. This is why it is very important to protect their eyes as well as your own. Glasses that block out at least ninety nine percent of harmful rays are recommended.

It does not matter if your lenses are plastic or glass. Both can be good for shading you from harmful rays. Make sure whatever ones you do buy have a UV absorption of 400nm. This means they will block one hundred percent of damaging rays.

Reflected glare is light that comes back at you from water or a smooth surface. Polarized glasses will stop this glare from happening. They do not block UV rays. It is possible to get both polarized and UV blocking lenses together. This would be good for any outdoor fun and driving.

UV protection is not based on the color of the lens in your fashion sunglasses. You can get a light amber lens and still have better protection than if you had a dark gray lens. The color of the lenses only matters for the protection from HEV rays. HEV stands for high-energy visible radiation. This will sometimes be called blue light.

Ultraviolet light rays do have more energy than HEV rays, but HEV radiation will go deeper into the eyes and have damaging effects on your retinas. A reddish brown, bronze or copper lens is best for protection from these rays. The label on these glasses might say blue blocking. You can find glasses that will protect you from all of the harmful rays.

It is easy to understand why good polarized sunglasses are important for everyone. Everyone may not need polarized lenses but everyone does need to protect their eyes.
