Radians Cheaters Bifocal Safety Glasses With Clear Lensstar rating 4BobMarch 2, 2008Excellent for use with full face motorcycle helmet as these glasses have temples that are stiff and straight enough to slide between helmet and your ears. Very comfortable even on LD rides. Only negative is the cushioned nose peices will eventually tear. Still though I recommend these to any motorcyclist that uses or needs to use cheaters.
