### ⭐⭐⭐⭐⭐ Finally a solution!
*by S***7 on December 31, 2025*

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.
