I have several of Magnivision Titanium reading glasses. They are by
far the best I've tried, and I've tried just about every brand there
is.

There is just one little problem. The nose piece and the side pieces
are attached to the lenses with tiny bolts with a tiny nut on the
inside. Over time (few months), these work loose. If I catch them soon
enough, I can tighten them and they will stay put for another few
months. If I am too slow, the glasses fall apart.

The ones for the nose piece are much more likely to loosen, probably
because they get wiggled more.

I have tried superglue, but it really doesn't hold.

Can anyone recommend a way to secure these nuts? If it is permament,
so much the better. I don't know why they don't use rivets. I will
never want to loosen these nuts.

Go back to your eye doctor. They'll tighten up the frames, then use a
special pair of pliers to squeeze the screw. The pliers have a
cone-shaped protrusion on one jaw that spreads the end of the screw.

You'll get a free cleaning and adjustment, if your doctor is any good.


These are $20 reading glasses from the drug store.

Maybe I need a pair of those pliers. Do you know what they are called.
A search for "optical pliers" turned up a lot of choices, but not what
you describe.
