Rudy Project ImpactX?

Anybody tried these? Curious about how photocromic lenses work out. How fast do they change. Not of lot of details on the Rudy site.

They work well enough that I don’t even worry about them anymore. I just put them on regardless of the conditions and they seem to be just right.

I have broken several (Nike, Oakley) pairs of glasses while changing the lenses and not having to do that all the time will possibly make them last longer.
