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.

Thin. Need multiple grips on each side

Since I both my eyes required cataract surgery, I now need 'reading' glasses - not only for reading, but for anything I need to be able to focus on close-up. So I use lanyard on all my reading glasses, so they are always around my neck. The problem was the lanyard were easily pulled off the temples and the rubber attachments do not hold the lanyard on tight/securely I read somewhere (internet) to get small rubber o-rings, place on on each side of the 'temple buckle' to hold them in place SUCCESS!!! These are the right size! It takes a bit of 'manual dexterity' to get them on the temples, but once on. . . no more lanyard mishaps!

Too large to even come close to a snug fit. The ring is so large, it rolls off the hinge and back down the stem. It stretched out even more after 1 day.
