I bought a pair of Bolle' amber poly carb lens prescripion glasses about six years ago. My rx hasn't changed much over that period and I've found them to be a very durable pair of glasses. They are a kind of horn rimmed style with amber side shields. I haven't babied them and they have held up extremely well. No serious scratches even though they've taken a pretty good beating over the years. No cracked frame nor lense pooping out problems. I like the amber for the all around versitility they provide. Excellent vision in low light, dawn and dusk. I only need to take them off when it is actually dark when I remember I have them on.
If they break or my rx changes enough I'll replace them with a more wrapped style but for standing up to the punishment I've laid on them I'll probably stay with the Bolle's.
