WearMe Pro - Polarized Modern Black Square Foldable Sunglasses with Case

Okay this is a really dumb question, but if I accidentally sat on these would they be okay? I am really rough and dumb where I put my glasses.

do any of the folding glasses fit over regular glasses?

I see many reviews about the hinges breaking. Would it help to put a drop of oil on each hinge, to reduce stress?

do they replace it after breaking from normal use? ive only been using it as driving glasses and after a few months, now broke at nose section
