I wear glasses. Can't function without them. But... when the sun's rays get too bright... I squint and shield my eyes with my hand. It makes driving difficult, to be sure. So... after years of doing this, I finally wised up, made the investment and ordered a pair of prescription sunglasses. I got the brown tinted ones because they showed the world around me in a more natural light. I love them. At last I can see, inside and out.
