My left nose pad came off randomly, is there anyway l can fix it?

It depends. Sometimes the nose pad comes off and can be replaced. If the pad arm its self, the metal piece that attaches to the frame front broke, you might be able to have it soldered, but it is better to have someone look at it and tell you how they can fix it. Soldering never looks nice and breaks again soon anyways. We replace nose pads free of charge all day every day where l work. Go check out some of the places in the mall or something and see what they say.

and why in the world is this question in the optical section O_O
