1. Why UV protection is Important in Sunglasses Ultraviolet (UV) rays are higher in energy and do not fall within the realm of visible light. While many people refer to ultraviolet radiation as UV light, the term technically is incorrect because you cannot see UV rays. The three categories of invisible high-energy UV rays are: UVC rays. These are the highest-energy UV rays and potentially could be the most harmful to your eyes and skin. Fortunately, the atmosphere's ozone layer blocks virtually all UVC rays. But this also means depletion of the ozone layer potentially could allow high-energy UVC rays to reach the earth's surface and cause serious UV-related health problems. UVC rays have wavelengths of 100-280 nanometer (nm). UVB rays. These have slightly longer wavelengths (280-315 nm) and lower energy than UVC rays. These rays are filtered partially by the ozone layer, but some still reach the earth's surface. In low doses, UVB radiation stimulates the production of melanin (a skin pigment), causing the skin to darken, creating a suntan. But in higher doses, UVB rays cause sunburn that increases the risk of skin cancer. UVB

But UVA rays can pass through the cornea and reach the lens and retina inside the eye. Overexposure to UVA radiation has been linked to the development of certain types of cataracts, and research suggests UVA rays may play a role in development of macular degeneration. UV radiation from the sun can damage not only the skin of your eyelid but also the cornea, lens and other parts of the eye. UV exposure also contributes to the development of certain types of cataracts and possibly macular degeneration, People with low blood plasma levels of vitamin C and other antioxidants especially appear at risk of retinal damage from HEV radiation. When you're choosing sunglasses, look for UV-protection details on product labels. Choose sunglasses that block 99 to 100 percent of both UVA and UVB rays. Skip sunglasses that neglect to offer details about their UV protection. Keep in mind that the color and degree of darkness sunglasses provide have nothing to do with the sunglasses ability to block UV rays. Also, opt for wraparound sunglasses or close-fitting sunglasses with wide lenses that protect your eyes from every angle. Children generally spend much more time outdoors than adults, children are more susceptible to retinal damage from UV rays because the lens inside a child's eye is clearer than an adult lens, enabling more UV to penetrate deep into the eye. Therefore, make sure your kids eyes are protected from the sun with good quality sunglasses. Also, encourage your child to wear a hat on sunny days to further reduce UV exposure.
