Everyone should protect their eyes from the harmful rays of the sun by wearing 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.

Glasses that shade your eyes from the suns' rays are not only available so that you do not squint while driving or walking outside. They do not make them only for style or fashion. The main purpose of glasses that block out the light of the sun is for protection.

Exposing unprotected eyes to excessive amounts of ultraviolet rays over a short amount of time can cause photokeratiis, or sunburn in the eyes. This can be painful, and give you the feeling of having sand in your eyes. This is usually only temporary and hardly ever causes permanent damage to the eyes. However, long term exposure to this can be more serious. Which is why people need to be made aware of why they need to wear glasses that shade the eyes.

Scientific research has found that overexposure to UVA rays can cause cataracts and damage to your retina. Even though UVB rays have lower energy than UVA rays, over a period of time these rays can cause skin cancer around the eyes. In the short term UVB rays can cause inflammation of your cornea which causes temporary vision loss, lasting anywhere from 24 to 48 hours. This could happen because no eye protection was worn while out in the snow.

It is proven that 80 percent of your exposure to the sun happens before age 18. Children generally spend more time outdoors than adults this is why it is important to protect your child's eyes as well as your own. Look for glasses that will block out at least 99 percent of both UVA and UVB rays.

Plastic and glass lenses are effective at blocking out damaging rays. Look for labels that read UV absorption 400nm. This is the same as absorbing 100 percent of UV rays.

Polarized lenses will cut down on reflected glare. This light bounces off of smooth surfaces like sidewalks or water. The polarized lenses do not help with UV light absorption only with glare. You can get polarized lenses combined with UV protection; these are great for driving and other outdoor activities.

The color of the lens in your glasses is unrelated to the amount of UV protection they give. You can have a light amber lens and have the same UV protection as a dark grey lens. The color does matter for HEV protection though. HEV stands for high-energy visible radiation, or blue light.

High-energy visible light does have lower energy than ultraviolet light but the rays penetrate deeply into the eye and can cause retinal damage. For glasses that protect against damage from HEV light, a bronze, copper or reddish brown color is best. These would be called blue blocking lenses. It is possible to get all of the protection you need in one lens.

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