The frame is a little small side, even for small sized frames. So these really might as well be for kids or for very tiny adults. That said, they still are comfortable and the photochromic lenses do their job quite well. They donât seem to noticeably get really dark or really clear, but they very effectively block the bright light on sunny days and allow me to see very clearly on overcast snowy days. Biggest takeaway on these is that the frame is small, but the photochromic lenses do their job.
