I've heard that some sunglasses have only tinted glass and do not actually block or reduce UV rays. Because they are darker, our pupils widen and end up letting in more UV rays than normal, increasing the damage to our eyes instead of decreasing it. I have some old sunglasses and I was wondering if there is anyway to tell if it block UV rays. They have numbers and letters on the side, is there any chance that these numbers or letters are relative to whether or not they block UV rays?
