Instashades.

Don't forget glass photochromics such as Photogrey Extra, Photobrown Extra, Thin and Dark, etc.

Drivewear? (Not posative, but I'd think it counts)

DriveWear is "activated by Transitions"...

Fantom optics makes EXCURSIONwear lenses change ambient light transmission from 70% in their natural state to 11% in their darkened state, even behind the car windshield. Patients will truly experience all the benefits of clip-on sunwear in any setting…while driving, at the beach, or in any outdoor setting. Sounds similar to Drivewear.
