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.
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.
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. It will not matter if your lenses are dark or a light colored brown. Color only matters for blocking out HEV radiation. HEV is also known as blue light or high-energy visible radiation.
{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 easy to understand why good polarized sunglasses are important for everyone. Everyone may not need Hugo Boss sunglasses but everyone does need to protect their eyes.
