You could ask an optician for advice, you never know :) Luckily, spare glasses help ^^'

I also have a problem with my glasses: one of the arms broke. A screw and some super glue are holding it together temporarily, before the arm breaks again 🫠. Strong glue should do the trick until I can get it repaired at the optician's or get a new pair of glasses.

Some pictures in addition to the booklet.
