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!

mine took about 2 mins. But they don't work in a car because the car windows had U V protection.

Usually a few seconds-- like twenty to thirty on average.
