How to fix screw that keeps falling out of my glasses

I think this is a factual question (and not an opinion one), but mods feel free to move this if it needs it.

The tiny screw holding together my glasses frame around my right lens seems to keep coming loose. This is the third time in as many months and I am scared it will do it again (and lens pop out) when I'm doing something like driving or in a meeting at work.

I've tried screwing it in REALLY TIGHT, but it doesn't seem to help much.

I've thought about applying a tiny amount of clear superglue around it to help it not untwist, but I will probably be getting some new lenses in a few months, and the screw will have to be able to come out.

Help, I can't let a 1 cent screw defeat me!

You can try to shim it with a small scrap of paper, or a tiny sliver of wood.

I've heard that a drop of clear nail polish will help, but won't hold so tight that you can't get the screw out when you need to.

Loctite didn't seem to sell any of their products near me.

I might have to try this. I will still have to go out and buy some (the woman of the household does not do her nails, which is just fine with me.)

Rubber cement will work for tiny screws.

I lost one of the screws in my glasses a year or two ago, and replaced it with a bit of paperclip poked in the hole and wrapped around the frame at that spot. It works fine, and is hardly noticable.

Elmer's glue is good for this too.

If you have anything resembling an automotive parts store around you, they will have loctite...

But the suggestion of nail polish will most likely work just fine.

You could even try a drop of paint on the threads before you screw it back in.

Unless one is actively looking for nerd fashion.

This makes about the tenth reason you are one of my nerd heroes.

I came in to suggest this very thing, as I've resorted to this myself in the past. It works fine.

Do people still use hairspray (I mean, other than Amy Winehouse)? I recall using this for keeping tiny screws in.

Yes they do. It makes me sneeze, so you can bet I know when someone has used it.

Crazy glue. Works a treat.

In fact, I've glued my glasses to my head permanently this way. Never have to worry about them falling off, no matter what the activity.

I have lost a few of those little screws over the years, never to be found again. Better than a paper clip a bit of copper wire can be used to make a C or even a rivet as it is much softer to work with.

Apple Cider...

My sunglasses have a screw that gets loose every now and then, but two years ago I took part of a typical New Year celebration in my home country, basically a large crowd gathers in the old city and a gigantic apple cider soak-a-thon ensues. I had my sunglasses on during this and over the months I noticed that the screw didn't loosen any more.

If you want to get more mainstream you can unscrew the thing and clean the screw and hole with alcohol (or better, contact cleaning spray) to remove oil from your skin that may have accumulated there. If after this it still gets loose is time to put a little instant glue on that sucker. Tighten the screw, use a needle to pick up a small drop from the glue tube and apply that to the screw head. That should do.

Take them to any local optician. The screws we use for replacement these days have a coating on them that seems to keep them in place longer. You should not be charged for this, whether you bought them there or not. DO NOT use super glue. Loctite or clear nail polish is fine. If the barrel of the frame is stripped, your optician can use a screw with a hex-nut, but that is somewhat noticeable on a lot of frames. When tightening the screw yourself, do not force it to "get tighter". When it stops turning, stop trying. Otherwise, you can inadvertently strip the barrel.

Good luck.

But Loctite makes SuperGlue brand super glue, which you already mentioned?

Take out the screw, and leave it and whatever bit of frame it goes in in some rubbing alcohol overnight.

The oils from your skin (or head-related products) coat threads if they get a little loose on their own, which is why they keep coming loose again afterwards.

I solved this problem with my glasses by using a slightly larger screw. Glasses repair kits are sold with many different sizes of replacement screws.

I used a garbage bag twist tie wire with the paper part stripped off. You can't see it and it works. I got tired of having to drive to the optician's every time a screw fell out and got lost. I had glasses for 5 years that got beat up terribly and the screws rarely fell out. My newest pairs have had the screws fall out numerous times, the first times within a month of purchase. I highly doubt that they are making better screws these days.

If anyone's interested, the proper Loctite for this use is the purple 222MS.

I had this problem for years and years, then I upgraded to a better, more expensive brand. The new screws do not come out, no matter what. Something in the design of the screws prevents them from loosening. I don't know why all brands aren't like that.

Perhaps, but I didn't have any copper wire on me at the time, but I did have a paperclip and a needle-nosed pliers (this rendering the harder metal workable).

The problem with a lens screw is that once it loosens at all, the lens starts to move around in the frame a little, which bends the frame slightly, which means no matter how much you tighten the screw, the two sides of the frame will never quite sit flush again, which means the screw can't be fully tightened, which means the whole process starts all over again....

Related question: If the barrel has been stripped, is there anything that can be done about that?

You can re-drill it if there's enough frame and use a bigger screw, or use a bigger self-tapping screw sometimes, but generally, no.

My optician recommended this also for my last pair, for which the screws fell out all the time (including in the middle of Alaska). My current pair has been fine.

I recommend buying a glasses repair kit for a few bucks. I never go anywhere without mine anymore. Especially good if you can't find the damn screw.

Superglue will work, but you migyt want to apply it to both the top and bottom of the screw. As for your new pair, if the loose screw happened a lot, short of poping out, you might want to check about changing the shape your temples (the "legs" of the glass that go to the ear). I have a wide head and pulled my spring hinges to the max and loosened screws. I broke one hinge recently and when both temples were replaced the optican curved them to relieve the stress on the new spring hinges. Also, brands matter somewhat. My previous glasses (from my optometrist) lasted 10 years under the stress, but the new pair (lenscrafters) which I had repaired last barely a year.
