Although most people are aware that they need to protect their exposed skin from the sun’s rays not everyone understands that eye damage can occur from the sun too. A pair of good sunglasses goes a long way towards protecting the eyes from damaging UV rays and blue spectrum light waves.
Both Ultraviolet A (long wave) and Ultraviolet B (short wave) rays have been shown to play a role in premature skin aging, skin cancer and eye damage. UVA rays penetrate deep into the eye and UVB rays damage the cornea and lens. A good portion of the sun’s glare comes from visible blue light waves which is the light that gives the sky its blue colour. Scientists believe that exposure to blue light waves over many years affects the retina and contributes to macular degeneration or even blindness in some people over 60.
For the best protection invest in a pair of good UV blocking sunglasses. Wrap around sunglasses block the UV rays from coming in from the side. Also reduce the risk of macular degeneration by wearing sunglasses, blue blockers, that block the blue spectrum light waves.
The lenses on blue blockers contain a yellow tint.
The sun’s rays are strongest between 10 a.m. and 4 p.m. so during that time either stay indoors or look for shady areas outside. A broad-brimmed hat or visor combined with UV and blue light blocking sunglasses will help shield the sensitive skin on the head, neck and around the eyes. Cloud cover does not block UV rays because UV light is invisible radiation and can penetrate clouds. Remember to wear sunglasses for winter activities too. Snow can reflect up to 80 percent of the sun’s rays giving unprotected eyes a double dose of damage. Polarized lenses contain a special filter that blocks reflected light and reduces glare.
Whatever the weather or location the outdoors can still be enjoyed by the whole family as long everyone’s eyes are protected from UVA rays, UVB rays and blue light.
