Reflecting visors?

Apart from looking cool

What other reason do you need?

People try to stare you down at the lights, and they face their biggest enemy...

THEMSELVES.

Seriously, go get one.

A visor that reduces the amount of glare is a must. We do not have an ozone layer here...

Clear polycarbonate, by dint of its physical nature, blocks most UV light anyway. I can't remember the figure, but IIRC, it's at least 96%.

I gotta clear as well as a tinted and swap depending on the weather. With the clear one my glasses still go dark so I assume it lets in enough UV. Rather fancy a reflective gold one though, expensive ??
