Replace Sun Glasses Every Two Years

September 13, 2016


Living in Florida, we have to protect ourselves from the sun's rays.  We use sunblock for our arms, legs, neck and hands.  Hats for our heads and sunglasses for our eyes.  However if you have somehow been able to hang on to the same pair of sunglasses for more than two years, it may be time to say goodbye to them.  Scientists at the University of São Paul in in Brazil have developed what they call an aging test for sunglasses that uses a sun simulator lamp to find out how well they hold up against UV rays. It found that lenses start to wear down in about two years, exposing your eyes to dangerous UV rays, which can cause cataracts and macular degeneration. So ditch your older pair and look for a new pair and when searching for replacement shades, make sure your sunglasses are oversized or wrap-around your eyes for maximum protection.
