Arms of my glasses broke off, how can I keep them on my nose without having to replace my glasses entirely?

duct tape

This right here is the reason I switched to contacts. I still have my old glasses with one arm held on by duct tape

Medical adhesive over your nose. Careful though, if you put it on your eyebrows it will remove them.

@lorentz oooh that eyebrow thing would be painful…

Glue back the handles on before you give yourself vertigo. Also, depending on your age using alternative methods for too long can worsen your eyesight. repair them as soon as you can.

Superglue them to your face

Or.. You know.. Epoxy-glue the arms

Make new frames from steel wire

@electrineer sweat would make that rust in no time. 👀

Just upgrade to contacts. I'm slower with glasses on. It's probably something psychically. I'm just not used to turn my head like you do with glasses. I like to look at you and roll with my eyes while seeing stuff

@NoMad but you would still C fine

Rock some of these bad boys like Fritz Haber.

@electrineer no you can't. It messes with the focal point, so you strain the eye muscles and your eyesight gets worse.

@mostr4am it is duct tape, but there is also a brand called Duck Tape. They sell specialty duct tape. So it is confusing. My guess is they wanted to trade mark Duck Tape and couldn't trademark duct tape as it is generic.

Screws.

Rubber bands.

Tape them in place.

Buy a fake nose/moustache/eyeglasses disguise and replace the fake lenses with your own.

Weld them to those 70s around-the-head braces.

Fashion some shoulder pads featuring a pair of miniature cranes to lift your glasses into place.

Use a couple of drones with proximity sensors that constantly fly a few cm from your face.

Hire a professional to hold your glasses in place as you walk, or sit and work.
