One of the side screws on hub’s eyeglasses became loose and caused the frame to gush open on several occasions. Thankfully the lens just stood precariously still and never once dropped, while the upper part of the screw remained intact. Hub could feel that re-tightening the screw wasn’t achieving a really snug fit.
When it eventually burst open again suddenly, at his workplace, he resorted to superglue to hold down the screw in place, and hurry off to attend his meeting. Then he forgot all about the matter. Now a few months later, late one night, the superglue surrendered. This being his only pair, I offered him my spare but my higher-than-his-degree isn’t very suitable. And we also ran out of superglue.
That’s when I remembered this tip! But we couldn’t put it to use in our case as the upper part of the screw is still superglued stuck while the lower end has uprooted. Then somehow I thought of thread as a temporary fix.
I wrapped and knotted tightly a few times using the strongest thread in my possession, i.e. bead crocheting thread, though most sewing threads will be good enough. And it has worked out nicely actually (with no vigourous activity allowed, just in case). Looking at it, I find that the thread has added a cool accent that’s better looking than securing with scotchtape.
In the meanwhile hub has made a new pair of glasses.
