Intro: Portable Reading Glasses. on the Go Reading Glasses.
If you are like me and hate glasses, here is an option.
Find inexpensive reading glasses and cut lenses out, drill a hole and attach to your keychain.
I have multiple lenses, one on my key chain, one on my wife's keychain and one on my lanyard at work. When I can't see something, I just pull my reading glass & I'm ready to go.
Works like a charm, no more embarrassing moments at restaurants trying to read receipts.
