I have way too much time to sit and think at work.

It probably doesn't exsist but I got the idea from those glasses commercials. What is it, transitional lenses. In sunlight the glasses tint, in dark the tint goes away.

Any chance there is a window tint like that, where windows only tint in sunglight? I doubt it but still, couldn't hurt too much to ask.

Can't feel it... must be fine!?!
