Eyeglass Frame Grips--Hinge Tighteners (pack of 10)

These tighteners really do work, but a caveat here. They are extemely hard to get on if you have Rayban's like I do. I have a new pair of Rayban Wayfarer prescription sunglasses. If it weren't for the review of "Brother in Christ" I would have given up and used rubber bands. The secret here is: soak them in hot water first for at least 10 minutes.Don't boil the water, but get it as hot as you can from the faucet and put it in a small bowl and cover it. Wait about 10 minutes and you will be surprised at how malleable they be. I had to coax them over the fat part of the Wayfarer stem, but once I got them past that, they sailed right onto the hinge. When you are placing them, hold the stem away from your body and coax the tightener along the stem. You will need a degree of patience in addition to the hot water, but believe me, if I could them onto the hinge, you can too.Another caveat, you will probably need to put 2 on each side. I had to because the Wayfarer's are a bit loose. But 2 on each side did the trick. The other good thing is that they are hard and not likely to soften and go weak on you any time soon. So far, I've not had any problems with my glasses sliding down my nose. They stay right in place and give me good protection from the sun. I highly recommend them but don't forget the hot water!

These are worthless for the advertised purpose. They're bigger than will fit on any pair of eyeglasses I have ever seen. Upon examination they appear to be grommets of the sort used to protect wires passing through holes in sheet metal panels or boxes.

These do exactly what they say and have stopped me from pushing my glass into place. Extras for other glasses like reading glasses and sunglasses. Fit is no longer an issue and a perfect solution.

These are large, will not fit on an eyeglass hinge will only work on the ear piece frame.

I replaced the hanging strap for my drug store reading glasses with these rubber hinge rings. One ring on each hinge tightened up the hold on my (narrow) face. No more slipping, no more catching the glasses as they fall, and no more wrestling matches with the strap. After reading the reviews, I was anxious that the rings would be difficult to put on. I live in the NE and received the package on a cold day. Right out of the cold package, these rings simply rolled up to the hinge. I tried two rings on one hinge and changed my mind- the ring rolled off despite its tight fit. The best part is being able to put the glasses open around my neck and the hinges keep the arms tight enough to hold the glasses securely under my chin when I don't need to use the glasses. BTW, a pair of these rings come with most of the small eyeglass kits sold at the grocery or drug store check out. I used to toss them!

Great for tightening frames but wish they came with more for that price. Didn't need the screwdrivers.

Like the title says, this must have been some kind of inventory mix-up at the warehouse. These o-rings are huge and would never work to snug up the hinges on eyeglasses. I've bought the correct little o-rings elsewhere and they're very small and thin. These obviously are not it. By the look of some other reviews, I am not the only one to have this problem.

There are AMAZING!!! I had a previous pair of Ray-Bans that the plastic kept stretching out too, sliding down my face, and wish I knew about these years ago! I've only had these glasses for a couple months, only wear them at nighttime (since I wear my contacts during the day), and had to have these adjusted like 4 times already because the plastic keeps stretching back out. These were so loose they kept sliding down my nose even at the slighted head tilt, but I only needed 1 band on each hinge (pictures attached) and they fit PERFECTLY now! My frames aren't super thick either (the arms are only about 1/2 " wide) and the band slid right up into the hinge! I didn't soak the bands in hot water either, as a previous reviewer recommended, and they still slid right on w/o any issues. Depending how large and loose your frames are, perhaps you'll need more than 1 band on each hinge, but for mine 1 was enough. I'd try wear them for a couple hours with 1 hinge before loading several bands on because they'll stretch out a bit. These are the best thing ever and super reasonably priced! We'll see how many months I can get before having to replace the bands, but either way, for the price and quantity you get it's a much better deal then taking the time out of your day to have your glasses adjusted all the tim. Plus, that can wear our your frames faster (my last pair of Ray-Bans started cracking on 1 hinge because they were being adjusted to many times). Overall, these are incredible and I would 100% recommend! I'll be buying more when I run out.
