Add optical dehydration to the list of problems you didn't know you had. It turns out if you watch too much TV or obsessively game, you are at risk of forgetting to blink, and if you stop blinking your eyeballs will dry up and fall out.

Fortunately, the good people of Masunaga Optical have come up with a technical solution which, at a cost of over $400, is in itself an economic stimulus. The Wink glasses work very simply: If you don't blink for five seconds, the glasses will fog up so that you can't see who you're shooting. As soon as you blink they clear up. Technology! What will we think of next? Maybe an aid to remind us to breathe or swallow?

On a positive note, the cost of the glasses will make the price of that Xbox 360 seem justified.
