I’ve bought a second glasses holder in the hope it won’t keep slipping off the arms. This is an ineffective product design. It is really annoying as I am in the middle of renovating a house. Every half hour I find the glasses are dangling by one arm, and I have to reattach the so called holder. 

There must some way I can modify these silicone bands so they attach to the arm and resist moving more than they do. The small spring simply slides back.

Perhaps a dab of silicone? Crimp the spring? I must not look unsightly.
