Good Lens for summer holiday

All eyes need protection from the burning rays of the sun. The most dangerous rays are called ultra violet (UV) and they are broken into three categories. The shortest wavelengths, UVC are absorbed in the atmosphere and never make it to the surface of the earth. The middle range (290-315nm), higher energy UVB rays burn your skin and are absorbed by your cornea, the clear window on the front of your eye. The longest region (315-380nm) called UVA rays, pass to the interior of your eye. This exposure has been linked to the formation of cataracts as this light is absorbed by the crystalline lens. Once a cataract is removed the very sensitive retina is exposed to these damaging rays.So need sun lens to protect our eyes.

Research shows that long-term, unprotected exposure to UVA and UVB rays may contribute to the development of serious eye
conditions such as cataracts and macular degeneration.Sun lens help prevent sun exposure around the eyes which can lead to skin cancer, cataracts and wrinkles. Sun lenses are also proven safest visual protection for driving and provide the best overall
wellness and UV protection for your eyes outdoors.
