Why Do People Need Blue Light Blocking Photochromic Glasses? Anyone who wears glasses knows what a hassle it can be to have to carry around separate sunglasses for when you are outside.If you are constantly finding yourself leaving your sunglasses at home, or misplacing them, photochromic lenses may be a great option for you. Photochromic lenses are a special type of lens that starts out clear and turn dark in the bright sunlight. They offer a convenient way to care for your eyes outdoors from sunlight and bright light without having to carry around a pair of sunglasses.
