I'm pretty sure someone though of this....
 

But i'm going to post and see if it exist. I was thinking today what a pain it is to carry an extra visor in my back for the night so I was thinking about glasses that change colors according to light. Do they make lenses like that for helmets? In the day time it will tint dark and at night it will be clear? I got a shoes helmet tz-r!:eek:

Fog City makes an insert that sticks to the inside of your shield that does that. I wear sunglasses and keep a pair of clear ones under my seat.

it advertises a reduction of 98% of UV light with the amber... I thought the shields already reduced UV light with clear.......
