What a great idea!
I currently have 3 pairs of cheap supermarket reading glasses dotted around the house and another pair permanently in my handbag The older I get, the more I seem to need them...and the more I seem to mislay them 
Indoors, they're on for reading, writing, using the computer, knitting, sewing, following recipes....My daughter asked me to sew some badges yesterday on to my grandson's Cub jersey , using invisible thread. Just threading the needle was a challenge...requiring
and
Outdoors, I need them in the garden, deciphering the small print on the seed packets, bug spray, plant food etc....
Shopping, they're on and off all the time, checking ingredients in the small print etc.
In fact, I'm beginning to wonder if there's anything I can do without them
