carla-fisher - Sunglasses worn all the time can make your eyes even more sensitive to light, so it's important that we try as best we can to stay in normal lighting. The key for me is usually to stay within the right KIND of lighting. I must wear sunglasses indoors if I am under fluorescents or LED's. Some ambient lighting from outdoors isn't a problem for me normally in the house, but if it's bright, then I'm in trouble.
