Spectacle screws: How to stop them coming lose?
What's the best way of locking them in that won't invalidate your guarantee from the optician? Why don't they do this for us? If I don't tighten the screws on my varifocals on a weekly basis the RH lens drops out! -- Graham %Profound_observation% |

My previous pair where doing that,turns out the person who put the lenses in had cross threaded the damn screw and it worked loose over a few days. Had the cheek to say I done the damage. |

Forgot to say... If you really want to secure a fix? a piece of thin fusewire fitted into the frame screwhole and then screw in the screw and cut off the excess fusewire sticking out. |

Graham. laid this down on his screen :

If I don't tighten the screws on my varifocals on a weekly basis the RH lens drops out! A small dab of Locktite on the thread -- Regards, Harry (M1BYT) (L) http://www.ukradioamateur.co.uk |

As someone else said, loctite, or if you have some handy a dab of touch up paint on the screw head with a bit of overlap should stop it turning. |

If I don't tighten the screws on my varifocals on a weekly basis the RH lens drops out! You should try the pair that one of my kids has just got. Lens fell out, screw missing, so I took the specs back to the optician to sort. They couldn't; transpired they were "unusual" and they had to send away for parts! Took almost a week. Less than a week later the same thing happened again, so I took them back to the optician again in a strop. Turns out they'd got a complete new duplicate "unusual" pair in previously to sort us out, which meant that they had one more screw left to fix it the second time. On closer examination, apparently the way these work is that they have *two* screws in either side of the lens, one male and one female - like mini versions of those plastic paired screws which you connect adjacent kitchen units together with. You have to hold prevent one screw from rotating using a one slotted jeweller's screwdriver while using a second screwdriver to turn the head of the other screw 180 degrees opposite IYSWIM. A *lot* easier said than done, and hardly surprising it's impossible to nip the bloody screws up tight enough to stop them working loose. Fab design, huh? I've told them next time it happens I shall expect a new pair of specs... David |

You said it's the RH lens that 'pops out' - chances are you're right-handed! Seconded. Loctite and a bit of care when putting them on and taking them off. My bird used to work repairing glasses and most frames end up knackered because people stretch at the hinges taking them off with one hand. |

writes [snip] them off. My bird used to work repairing glasses and most frames end up knackered because people stretch at the hinges taking them off with one hand. I would suggest that if as you say, that taking them of with one hand is what 'most' people do, then the frame manufacturers have failed to provide a product which is even close to meeting 'most' of their customer needs. viz Ford: Yeah we have a problem with people trying to start our cars. Engineer: Well, thats their problem, they should know better. /viz I do not doubt your or your 'birds' view, and I do understand that neither of you are the designers of such frames but I really don't accept it is my fault. I'm right handed, it is how I was born. Someone |

Looking at them more closely, under a magnifying glass, I see 'Silhouette' next to 'Made in Austria'. They're completely frameless - the only metal bits are the temples and the nose piece, which are attached directly to the lenses. |

I'm right handed, it is how I was born. Most people also replace their frames every time their prescription changes. Sprung hinges go some way towards reducing the problem, but eventually play develops in the sprung part of the hinge. The only other option is to make the glasses so rigid that people can't take them off by stretching them around their head, and I doubt people would buy glasses that heavy or bulky. IMO it's more akin to getting in and out of your car via the windows and then complaining that the doors all scratched. It is something that should be mentioned when people buy glasses or bring them in for repair. |

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember somebody saying something like: viz Ford: Yeah we have a problem with people trying to start our cars. Engineer: Well, thats their problem, they should know better. /viz I don't recall that being in Viz. Not very funny. -- Dave |

How I agree. The frustration I have in finding a comfortable pair at about £350 a throw! However, I suspect that what we are wanting will provide another opportunity for "New Designer fitted wonder Specs." "I'm pleased that you find these comfortable. Our suppliers have gone to get lengths to make these." "That will be £450. Thank you, sir." ! |

Having the frames made to fit with regards lens spacing and arm length is important to the correct functioning of the glasses. You need to naturally look through the right part of the lens, even for simple prescriptions let alone anything vari/bi focal or with astigmatism correction. Proper fit and frame size is what a proper optician(*) will do but you can't walk into a proper optician have a sight test wait 30 mins and walk out with a new pair of glasses... The optician I use fits the frames to my head properly (*) There are specific names for "opticians" depending on their qualifications. They messed with them a number of years back I think the one you really need is an "ophthalmologist" rather than an "optician" or "dispensing optician". -- Cheers Dave. |

Now they live in the Channel Islands with hundreds of millions of pounds and you have made in China, one size fits all spectacle solutions. Everyones a winner, eh? |

But, the frames are still sold without any opportunity for variation of lens spacing, arm length etc, i.e. there is one D+G or Polo or no-name special frame and if you don't fit it - tough. IIRC the sprung arm was introduced to overcome the problem of non-fitted glasses sliding down ones nose by gripping the wearer around the temples in a migraine inducing grip. My father has some pre-deregulation (or whatever it was called) half moon glasses which he uses for very close-up work. They stay on his head without any effort nor do they require pushing up his nose periodically. Compare this with his current varifocals which require constant adjustment and have arms which are too long. My left ear is slightly further forward than my right ear but there was no suggestion that the arms of my glasses (purchased 9 years ago) could be adjusted to match my head. Richard |
