    What do optometrists put into or onto the screws in spectacle frames to stop
    them coming loose?

    If it is a special product, is there a common household alternative that
    will also do the job?

    It should not require a visit to a spectacle maker just to fix a loose

    (I have done the homework, the Google searches and asking older spectacle
    wearers, to no avail.)

  2. I have never tried this on eyeglasses before, but I would suggest
    trying Loctite Threadlocker. It comes in different strengths, and
    works great on nuts and bolts.

    I believe that LensCrafters will fix them for free, if you look halfway
    interested in getting a new pair (even if you don't buy).

  5. I have used a Loctite 242 product. I did not keep a notebook. I Never had
    probems with the screw getting loose after that. I think that I had occasion
    to remove one of those screws without much trouble.

    All the chains will fix them for free, which is especially handy once
    you have lost the little screw.

    Hello Robert,

    Thanks for the Loctite advice.
    I suppose you wipe it onto the thread of the screw before you install the

    It was hard to tell whether the nail polish suggestion was good or not.
    If it was, anyone could use it.

    I am aware that most optometrists will tighten screws that have worked
    However it can take days to organise that, and we often need to use the
    glasses in the meantime.

    Many opticians in the US will do it for free (even if you did not buy the
    lenses there) while you wait. Only takes a few minutes.

  9. I think the correct product will work its way into the threaded portion.
