I’ve got some Oakley Photochromic racing jackets and I’m very pleased with them.
I tried lots of cheaper reaction lenses sunglasses including not practically cheap ones by Endura and Julbo and was very disappointed with them. Their range of change was always pretty poor and/or they slightly distorted my vision. After trying all these different glasses I decided I could have just bought some Oakley’s after what I’d spent on these.
My Oakley’s do a great job of reacting to changes in light and I always ride them when cycling in the day time.
Although they look virtually clear in very low light I didn’t like riding with them at night. I found it difficult to pick up the detail on stuff like rocks and roots when wearing them. I got some clear lenses at the same time when I bought them so I use these for night riding (or no glasses at all).
