Pogue's cheap, unexpected tech gifts #2: ThinOptics glasses

Once you hit 40, your eyesight starts to go. Simple human fact.

You need reading glasses. In a lot of different places.

Here’s one cheap, brilliant way to get them: In the form of ThinOptics glasses. They have no earpieces—a comfortable silicone spring gently grips your nose—so they’re tiny enough to slip into the back of a phone case ($30 with two pairs), to fold up into a keychain ($25 with two pairs), or to live inside a razor-thin plastic pocket that you can stick anywhere ($20 with two pairs).

Guaranteed for life, and a real godsend in a pinch.
