frames almost seem to be possessed since every one broke in almost the exact same spot.they broke while wearing them, not putting on or off.take and extra pair if you leave the house.
the focal magnification area was much smaller than the lens. it seems all of the magnification was in the center 1 of the lens. wearing them was disorienting and not useful. returned.
although these are affordable they are not very durable. the plastic breaks at the joint above the nose. typical wear time before a break is about 45 days. going to look for a better product, i'm hoping there's something out there that is more durable yet still affordable.
