After my cataract surgery earlier this year I finally got the soft contact lenses I’ve wanted for years, now I’m after some photochromic glasses, after looking on the old interweb thingy it’s raised more questions than answers to the extent that it’s fried my head a little, I’d like some that change from dark to light and back again quickly but I don’t want to spend a fortune, can anyone recommend a decent pair that aren’t mega expensive, I’m not bothered about fancy brand names as long as they do what they’re supposed to do, thanks in advance guys
