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

Take them back and let the optician deal with it.

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.

Summats wrong with them then, is the joint fully closing when you tighten
them?

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.

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...

They're flexible, lightweight titanium.

Agreed they must be new if under warranty and if there is danger of the
warranty being voided by "unauthorised repair" then it is the only option.

A proper opticians won't have a problem with this, a buy one get one free,
prescription glasses in 1 hour shop might...

Lindbergs then. I can't see the point TBH - yes, they last ages, but
relensing them is as expensive as a set of run of the mill frames.

Try using _both_ hands, to remove your glasses. 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.

I don't see a name on them - just 'made in Austria'.
They're very lightweight, important for me due to a strong prescription,
and I _never_ have to retighten or replace scews.

If you could recall or use a magnifying glass that could be helpful to me. I
use varifocal plastic and have tried several different styles of nose
bridges, I do find the experience painful and wish to minimise the load!

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.

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.

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.

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.

And why can we not - since deregulation or whatever it was - now buy
frames that are made to fit our heads/ears/noses, i.e. with arms etc of
different sizes. My limited experience of buying glasses, having had
the same pair for over 10 years, is that one must hunt the shelves to
find a pair that fits rather than choosing a pair that one likes and
having them made to fit.

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".

Silhouette are very good.

if you want to look at some alernatives before paying Silhouette prices
type:

lightweight hingeless screwless rimless

into Google and have a shop around.

Because the price of glasses was apparently a rip off.

But Doug and Mary Perkins fixed it for you by being the largest driving
factor behind deregulation and bringing you Specsavers.

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.

No, it's an optician... an ophthalmolgist is a qualified doctor of
medicine who's gone on to specialise in eyes: you don't get many of

The two terms are, AFAIK:

Ophthalmic optician
Dispensing optician

And then the ophthalmologist in the hospital.

Optimetrist is the name these days and the one you want on the High St,
one step below an Opthalmologist. A Dispensing Optician can't do eye tests
but can fit and advise etc.

And then the ophthalmologist in the hospital.

Aye, as I said they messed about with the names years back and I haven't
