I had a pair of progressive eyeglasses with rimless, unfortunately it felt to the ground and been trampled by someone when I was playing basketball. I am interested in wearing progressive eyeglasses so much so I want to buy a new pair one. Compared with the traditional way, buying eyeglasses online is very easy and cheap. Could you recommend me some good websites selling eyeglasses online, thanks for your help?

How long does it take for the Lens to change color when you go outside? I have had mine for 3 days now and they have not changed color when out doors. Is there something wrong with my photochromic lenses? I just have bought them for only two week. Could I go to change them? thank you for any help!
