Hello naco. You said the glasses that lenses are dark in the sunlight and are clear indoors. I think that is photochromic lens. Transition is actually a brand name of photocromic lens. The idea behind photochromic lenses is that they will provide the correct amount of protection for the varying light conditions you experience.
