I'm having to replace my glasses once a year because the frames bend out of shape
e.g. the arms get wider and wider and the glasses keep falling off. And one arm seems to twist downwards at the hinge. Even if I get them reshaped and screws tightened they are unwearable again within a few months! Boots and Specsavers (usually rimless).
What am I doing wrong? Or do lots of people experience this?
