In my experience, if the screw comes out once it will do it again
unless you put a bit of superglue or nail varnish on it to stop the
screw turning.

Yep, did that - I used superglue.

You have to be careful with that, I ****ed a pair of
sunnys with a fingerprint of superglue on one lens.

Acetone - nail varnish remover - is the easiest to obtain solvent for
superglue

I do not know whether it also dissolves polycarbonate lens coatings...it
does not attack polycarbonate itself
