Yep, all the time and no problems. If anything, as dark glasses, they don't get dark enough. Don't get me wrong, a lot better than no sun glasses at all.
Oh, they don't work in the car so you still need sun glasses for driving. I have a pair of dark glasses in the car I drive the most and another pair to take with me when riding in any other car. This second pair are very dark and work well for activities in very bright sunlight.
If anyone ever takes YOUR photo outdoors you'll be wearing dark glasses with no clear glasses to change into.
Walking from the sun into a dark room the lenses don't change as fast as I'd like and I find myself taking them off till the glasses adjust.
MOST of the time the Transition glasses are great, you just need to be aware of the limitations.
It seems there should be some technology to put a slider on the glasses temple to adjust the darkness of the lenses. Till then, I'll keep using the Transition lenses.
