Yes. I was in a restaurant with a friend recently and he couldn't read the menu. "I forgot to bring my glasses" may have been what he said, but the gist of it was, he left them at home.

I reached into my handbag and handed him the spare pair of 2.5+ readers I carry for myself and he ordered without having the menu read to him by me. After cataract surgery I no longer need corrective lenses, only close up for reading and computer work. I frequently "forget my glasses" in one room and end up using a pair I've left in another. At this point I probably have 10 pair of them around the house, by my computer and bedside, and the spare in my purse. They sell a good brand in packs of three or four at Costco for a very good price. (In Texas, US)
