Optic Shop Eyeglass Frame Grips, Hinge Tighteners - 4mm Inside Diameter, 48 Rings in Each Package

These are just what I needed to keep my glasses in place. The fit very well and were the perfect size. The price was excellent for the amount of grips you received. They seem sturdy so the quality is fine. My glasses are much more comfortable since using these. Would buy again.

These bands work well on my new eyeglasses. Glasses stay put as intended. The frames were the proper size, but I wanted them just a touch tighter & these worked perfectly.

Love my glasses, hate that they slide down. I’ve tried bending the arms, using heat, online hacks, just about everything to not need a trip back to the glasses place and then I found these. A simple answer to an annoying problem. They’re basically little stretchy washers and If you install them correctly, they will work. I use two on each side for an extra snug fit.

Worked ok to tighten loose sunglasses. I had to use 2 to tighten. Putting your sunglasses on your head loosens them. O

I received the product I ordered and it arrived intact and on the date promised. These eyeglass frame grips are useful and keep my frames from slipping.

one of the arms of my glasses bent out bad... I replaced the arm and found a part of the frame had broken off... these helped me to be able to wear my glasses regular instead of with a strap to keep them in place

These are huge and therefore useless to me

Thin. Need multiple grips on each side
