The glasses tint perfectly after I put them in the freezer for 24 hours before using them. Did not get super dark but dark enough even driving into direct sunlight I like this. In the summer it does not have fun lining and that is why I bought them so that my eyes aren't sweating. I used the kickback 24 photochromic with foam for the colder days. I can't say enough about global vision glasses way better than Bobsters.
These glasses do not tint in the light like they state. While they do work per the conditioning process per the instructions they will not tint during normal outdoor use. Location Arizona.
Glasses are well made however.
These lenses are great! They change from dark light instantly even on sunny day when entering shadeed areas. Fit nice too, very light and the grippers on the ear pieces are good!
