QYAJS Eyeglass Repair Kits Glasses Grips Hinge Tighteners Silicone Hinge Rings Eyeglass and 1 Screwdriver 6mm for Eyeglass Frame

They worked perfectly! My glasses were driving me crazy, they were new and kept falling on my face, and this did the job. Love the thin. Thanks!

I bought this kit for the small rubber discs which help stretched hinges grip again. These work well. Not easy to find. This kit also has a useful little screwdriver for spectacle screws, which could be very handy

The rings are a fantastic fix for a much tighter frame fit, however the screw driver is not useful, too big

I did purchase a pack of eyeglass hinge tighteners previously from Amazon (ProOptics UPC 075063010105). They were much too thick and too large to be used as advertised. They proved to be very visible and were not usable. It was not worth my time to even return them. I purchased the set of hinge tighteners shown above as a replacement. These were made by Janky Trading and were just as advertised. They fit my eyeglasses perfectly and work exactly as advertised. The Janky brand will be my item of choice and I will gladly recommend these to everyone.

The O rings work well for tightening loose glasses.
