Love these reading glasses, they go everywhere I do.
Now this is a lovely product! I hate carrying my regular reading glasses in the case around just for the sole purpose of being able to read small print in darkly lit restaurants. So I was forced to lean on people to "read" the menu for me or just ask the waitstaff for their "special". But these little keychain glasses work perfectly so I can now read the menu quite easily. And as you can see from the pictures it's small and fits in my pocket so it can easily come with me. Doesn't look too bad either. It's not overly comfortable (i.e., it won't replace your regular glasses) but it absolutely works for menus or other small print where you need a few minutes to read it.
Bought 2 pair of these a few days ago. Did the acid test last night at a dark restaurant. Popping the glasses out of their little case elicited the desired "oohs & ahhs", and they stayed on my nose without having to readjust every couple seconds. Getting them back in the case without fingerprints is a little tough, but I'm sure it just takes practice. Also, make sure not to push in and down on the little retractor button, or else it sticks. Just pull it down with a fingernail, and it works fine.
Definitely going to put a couple more pair on my list of stuff to just have laying around. Also, great for gifts for your nearsighted friends!
