How quick does lenses change when going from dark to clear and visa versa with transitions optical glasses?

Not quickly enough!


It takes a few minutes (not seconds, like in the commercial!) for the complete change to occur.


I even had to hold my glasses outside of my window to get them to change when I got in my car....there wasn't enough brightness to get them to change otherwise!


I couldn't stand mine, so I got rid of them!How quick does lenses change when going from dark to clear and visa versa with transitions optical glasses?
Usually a few seconds-- like twenty to thirty on average.How quick does lenses change when going from dark to clear and visa versa with transitions optical glasses?
1-5 MINUTE
mine took about 2 mins. But they don't work in a car because the car windows had U V protection.
