Sport Sunglasses Can Protect Your Eyes
Jul 15th, 2010 by fashion reporter
All people should wear sunglasses for protection from the damaging rays of the sun. Glasses that block out HEV, UVB and UVA light are the ones that are recommended. These will protect your eyes from at least possible skin cancer and cataracts.
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.
There is proof that before the age of eighteen, children are exposed to eighty percent of the sun they will experience in a lifetime. This is because kids spend more of their time outdoors than they will when they are adults. It is extremely important to make sure your child has protection for their eyes. Try to find glasses that will give ninety nine percent protection from both UVB and UVA 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.
{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.Ultraviolet light is stronger than high-energy visible light, but the rays from the HEV light go deeper into the eye. This can cause retinal damage. Glasses that protect against this would be bronze, copper or reddish in color. The label on these might say blue blocking lenses. You can get all of the protection against UVA, UVB and HEV in one lens.
It is clear why the right designer sunglasses are important to everyone. All people might not to have the entire combination of lenses but everyone needs at least the UV protection with Hugo Boss sunglasses.
