another glue-question: for eyeglasses frame, a NON-permanent glue?

[David Combs]

(Note: this gluing-question is unrelated to
the one I just posted -- I've got two separate
gluing-tasks to accomplish.)

I asked something like this some months ago, but
no one had a suggestion for what I actually needed.

So, I'll try again, and maybe state what I need
more clearly, I hope.

---- A parallel: masking-tape vs drafting-tape.

If you tape something down (onto paper) with masking tape,
you find that you can't get it off without tearing
the paper.

However, with drafting tape, it pulls right off. (Because
that's what it's *designed* for!)

---- I want something like drafting tape, but as a glue.

For gluing what? My eyeglasses: from time to time,
one of the lenses decides to fall out. Like when
I'm driving at 60mph, surrounded by huge trucks.

Not cool.

So, I asked the optician if he could glue the lenses
into the frame, so they wouldn't fall out (at all).

No, he says, because you'd never be able replace
the lenses (with a different prescription). Important
to me, because, as we all know, the freaking frames,
probably made by a chinese prisoner or burmese slave
at a labor cost of 25 cents, cost more than the lenses
themselves.

(Money not so easy these days, so I *need* to be
able to reuse the frames.)

--- So, my question: there *must* exist some kind of glue
that softens or loses its stickiness when you want
it to, perhaps by immersing it in almost-boiling water,
applying a voltage to it, blasting it with sound-waves --
*something*!

Any ideas?

Thanks

Lenses come out for one of two reasons. The screw that holds the frames
together is loose or the frames are stetched in which case you need new
frames. You could use a litttle silicone

No sir, not at the price those things cost!

Actually, I think the optometrist was a little sloppy
when cutting the lens to fit in my frame.

(I bought nice metal frames, for $99, at Cosco,
and they look like the $200 ones hanging on
my optometrist's wall.)

I especially think he goofed a bit is that he
recently told me that that would no longer
happen, since some new machine is now available
for doing a better job of cutting the lenses out
of the "blanks" that come back from the lens-maker.

>You could use a litttle silicone

How? What kind of silicone? How dispensed? How to
apply it. And to what. And will I be able to
get it off, ie get the lenses out, when I want to
reuse the frames for yet more powerful lenses ...

I mean, exactly what do I buy from eg home depot?

And then, how to put it on. What, take out the
lens, squirt on some silicone, then put the glass
back in?

Or is there some way that doesn't require me to
temporarily remove the lenses?

Thanks!

If the lenses and frames aren't plastic, nor have any plastic coatings, then
you can use DUCO cement. Works well for glass to metal.
It dissolves in acetone (nail polish remover). Same with usual glues, only
use as much as you need, makes for less to remove later.

So, in other words, the optometrist told you he cut the lenses too small
for the frame. It is all well and nice that in the future he won't
produce such poor quality. But you are wearing the glasses in the
present. Request that he remake the lenses at no charge to you.

The lens manufacturers will replace the blanks for free, even if it is the
optomotrist's fault. Your optomotrist will only be out his labor time
cutting them. Don't let him get away with screwing you.

If you know the lense were cut wrong why not get them to make new lense.

tell the optician that the glasses were not formed correctly around the
lens and they are not tight enough to hold the lens..... i had some like
that, they then put the frame into a pan of hot water( i guess that was
to soften the frame and they just grabbed it to form the shape of the
lense), worked for a while, but later the prolbem came back and lasted
until i quit using these $200 pair of reading glasses..... later got
some new glasses and they were made differently and worked alot better,
at least for the past year......

Thanks to all; will first try the elmers or duco cement.

Thanks!
