Easy fix.
I'm not old even though my eyes seem to think so. Anyway, I bought these after reading all the reviews. They worked great the first few days but because my cheap cheaters (i.e. glasses) have thin temples (i.e. the part that goes over the ears), they kept falling off. Having read the reviews, I expected this would be the issue... with these no matter who the supplier is. So, I cut a thin strip of electrical tape and wrapped it around the springs on the holders and it holds perfectly. You can't see the tape and they are snug as a bug in a rug. No more falling off.
