I have bought a little set of precision screwdrivers because my lens keeps dropping out of my glasses and I have to screw the frame back together.
I used the tiniest one tonight to screw up the frame but I turned it like an ordinary screwdriver. Why has it got a revolving 'circular thingy' on the top of the screwdriver? Are you supposed to turn that, rather than turn the whole thing? I did try but nothing happened, it just kept turning but the bottom of the screwdriver stayed still. There must be a technique to using it properly.
no, you turn the main handle, the little spinny bit at the top is so you can push down on the screw driver while turning it if you need to (to stop it jumping out a screw head)

I could be wrong, Tilly but I press the circular thingy into my palm when I am using mine....for my glasses....then use my fingers to turn the screwdriver. Keeps it steadier but may not be why it's there. x
The round twirly thing on the top is supposed to sit on the bottom joint of your index finger, this way you dont need to release the strew driver completely during turning, just release it with your fingers but keep it in place with this part of your hand. this means that you dont have to keep relocating a tiny screwdriver into a tiny slot. It works well.
I see. So it's like a stabiliser sort of thingy? I imagined it was something like a ratchet screwdriver thingy and you pressed it down and it went round..
Hopkirk, I have done that, many times. I think it must be a design fault with my glasses.
It's really embarrassing when you're in a meeting and you put your glasses on to read something and the flipping lens falls out!
Tilly - I have exactly the same problem with both my regular glasses and prescription sunglasses - very awkward - went to swap the normal glasses for the sunglasses last week and only one lense in the sunnies!! Other one laying in the case!! Have to keep tightening the screw on the normal glasses as well. Bl@@dy annoying!
Tilly, once you have tightened the screw up to the required degree put a tiny drop of thread lock or similar (obtainable from your local friendly hardware store or a male friend's toolbox) on the opposite end to the slot. It will almost certainly never come loose again.
If you've got a shop selling Airfix (or similar) construction kits near to you, call in and buy the smallest tube of poly cement that they sell, such as this one:

A single drop, applied to the top of the offending screw, will cure the problem. (I ready that tip somewhere several decades ago and I've used it on lots of pairs of specs since then, with perfect results every time).
Frames are getting too complex. For example, these days they seem to have some kind of internal spring near the hinge so the sides can push out a bit. Not that, that has ever been an issue. A solution in search of a problem. So guess what has recently broken, and meant the frames had to go back to be fixed. Precisely.
