Sunglasses Should Help Your Eye Sight
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.
Shade from glasses, is not only meant to keep you from having your eyes half closed when you are enjoying the outdoors or when driving. Dark glasses are not available so you look good. The reason for glasses that give shade to ones’ eyes is 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.
Researchers have found that long term exposure to UVA rays can be the cause of damage to your retina or cataracts. Extended exposure to UVB rays can lead to skin cancer around the delicate eye area. Short term exposure to UVB can inflame the cornea of your eye which can cause temporary blindness that can last up to 48 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.
Try to find glasses that absorb up to 400nm. This is the same as a label that reads one hundred percent UV protection. Either plastic or glass lenses that have these labels will be fine for blocking out damaging 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.
UV protection is not based on the color of the lens in your glasses. 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.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.
