How bout those mirror shields, cefalu. Ever try those? Real glare killers.
I know where you're coming from. My eyes are built for thick jungle forest. Can't stand bright sun. My fave helmet is a dual sport with a mirror shield. The dual sports all have a brim like a ball cap that helps shade the eyes, and then the mirror shield kicks ass with glare.
I just picked up a hundred dollar Bilt modular Friday at CycleGear. Has an internal flip down dark shield. Fifteen bucks more bought me a mirror shield. Rode a hundred miles in the bright sun today, slabbing up through Jersey and back, light sensitive transition glasses, mirror shield, and dark shield down. Like riding in a cavern. Pure pleasure. Try that.
