Instead of constantly pushing your glasses back onto your face like a stereotypical 90s movie nerd, we recommend wrapping the ends in a bit of heat shrink to keep them from slipping.
While it's definitely one of the more involved ways to fix the sliding glasses problem, it's going to look and feel a lot better than, say, slapping some duct tape on the back. All you need is a bit of heat-shrink tubing. You'll also need a source of heat—like a heat gun—but if you don't have a heat gun, you can always try something else.
They claim a hairdryer probably won't produce enough heat, but it's worth a shot, and a lighter might work if you're very careful, but the Hilltop Commercial Heat Gun is ideal. Whatever you do, just be very careful, and familiarize yourself with the safety of your chosen method.
