My Slippery Sliding Eyeglasses Solution by Walt barrett

I'm just one of those people whose eyeglasses won't stay on and it's an annoying problem and sometimes the most simple answers are right in front of our noses or should I say right behind our ears, but it only took me 80 years to figure it out! 
I solved the problem by making a simple set of friction grabbers from two elastic bands. They don't slide any more - It works for me!

The mad scientist !
