Just checking how long will it takes the transition lens to change color when in the sun? My Hoya transition lens still quite clear when standing in the sun for a few mins. But the shop when she put the spec into a uv cabinet for like 10mins n the lens become tinted...is this normal?

I think different lens take different amount of time. Mine if standing in direct sunlight in the afternoon takes about a minute but my dads one within 10sec can see it turn darker but takes longer to turn to the darkest color.
