Yesterday, my wife and I drove a narrow winding road that took me to the fourteen thousand foot summit of Mount Evans. Fortunately, the breathtaking trip was uneventful because I wore prescription sunglasses. I wondered how someone could make this challenging drive without appropriate eye protection and prescription glasses. Gradual loss of central and color vision are symptoms of macular degeneration, not uncommon in middle-age people. For further information, log on to the American Optometry Association regarding this eye disease. You wouldn't want to drive over the edge. It's two and a half miles straight down.
