Everyone needs to keep their eyes protected from unsafe sunrays by using sunglasses. The glasses that are advised by opticians are ones that protect against UVB, HEV and UVA rays. You will be saving yourself from getting cancer around your eyes and cataracts.

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.

When eyes are left unprotected from too many ultraviolet rays for a short period of time sunburn can happen. Not only does this hurt but it also makes you feel like there is grit in your eyes. This will only last temporarily and should not cause total damage. If you are overexposed to UV rays over a long length of time the damage will be permanent. This is why everyone needs to know why they should wear shades.

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.

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.

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.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 polarized sunglasses are important for everyone. Everyone may not need Hugo Boss sunglasses but everyone does need to protect their eyes.
