any of you guys have tried/used photo sensitive glasses?  how did you like them?

never tried them but but I've seen some. they go dark over the course of about 15 seconds, and take about 5-6 min to fade back to clear. they aren't as dark as normal sunglasses.

Have had them for many years. I love them as my eyes are very sensitive to light. They do freaky things if you get water on them while washing the car. The photo gray will spot temorarily corresponding to the water drops. Also, if you are working in a shadow with a bright sky, say under the hood of your car, you can get a line from the shadow that takes a few minutes to dissipate once you leave the edge of the shadow.

glass, heavy, my prescription was expensive and I miss them
