These don't survive falls
At $8 a pair, they are as good as you get at a supermarket for 1/3 of the price.  HOWEVER, the plastic is extremely brittle.  One of the lenses on the first pair I wore snapped cleanly in two after falling about 5 feet onto a tiled floor.  The supermarket/pharmacy glasses only chip when dropped. Maybe it was an unlucky bounce but seemed too brittle for something that's likely to be dropped. UPDATE: All three pairs broken by minor short drops within 4 months the second two pairs were badly chipped from knocks and falls - made from egg shells.
