Oakley Men's Radarlock Path Low Bridge Sunglasses

I use these sunglasses for cycling. They fit well. The shape of the frame are good for keeping the lens away from your face during exercise. However, there's a pretty significant design flaw. During cycling, I sometimes take off and put on these glasses with one hand. After a few of these, part of the lens, a tab, that locks into the frame will break off. This has happened twice already. The glasses will still work and the lens is unlikely to fall out but it affects the integrity of the frame causing it to be a little bit flimsy.
