I was an "early adopter" of photochromic lenses in the day when they had to be glass. At that time we had the choice between "Photo Grey" and "Photo Sun." "Photo Grey" didn't get as dark as "Photo Sun" but "Photo Sun" never quite lightened as much as "Photo Grey."
I didn't like either of them- I had both- because they didn't darken as fast as I could clip on my clip-ons, or flip down my flip-ups. For the merest fraction of the cost of photochromic or transition lenses I can buy a pair of polarized, UV-blocking, 80% tint clip-ons, or clip-on flip-ups, in my choice of tint, even at retail prices. (I never pay full retail, I always get them at the end of the season, when they're marked down 80-90%. Trust me, they'll work just as well next summer...) WHL Character is doing the right thing when no one is watching.
