Review on Bullhead Safety Eyewear BH10613 Photochromic: Optimal Eye Protection with Adaptive Lens Technology by Josh Garber

I like these glasses. I'm constantly in and out all day and don't have to wear dark and clear glasses - that's great. However, I did find that the helmet's light tint kept them from going as dark as possible, but they still got dark enough that I didn't blink. When I'm not wearing a helmet they get as dark as any sunglasses I've had. Finally, in my opinion, they are very comfortable. I can wear them all day and even forget they're on me. They also fit well so they don't slip off my nose or fall off my face when I look down. It was a great purchase. If you want something that is an inside/outside tint, get the transition/polarization colors first as they are transparent (no tint) when not in the sun.
