The popular Oakley Whisker frames with Drivewear lenses.
Transitions partnered with Younger Optics to offer Drivewear lenses--the first polarized photochromic to activate behind the windshield of a car. They block 100% UVA and UVB rays while blocking all incoming glare in the horizontal plane. The lenses transition from a light yellow/amber to a dark maroon, depending on the amount of sunlight.
As you can see in the video, the lenses instantly start transitioning when exposed to sunlight, and a full transition takes only a few seconds (as opposed to less active eyeglasses transitions which can take up to four minutes to completely transition).
@sumflow yes, it's in real time. granted this is in full sunlight tho. in the car it doesn't necessarily transition this quickly.

pause at 0:18 to see the difference in color between the fully transitioned and non-transitioned lenses.
