I had my doubts about
"I had my doubts about buying these because I was unsure if I could change the lenses. I YouTubed a how to video and it ended up being really simple. These are everything you expect of the best transitional lenses. I wear my brick with photochromic lenses at my union pipe fitting job. I have a clear line of sight inside buildings, and when I have to be in the sun It’s not so bright. I highly recommend these for anyone thinking about buying or replacing their brick lenses."
