Japanese have created blinking glasses
A wink can convey all kinds of meanings. But what if you're looking at someone and their eyeglasses wink back at you?
Wink Glasses 2013 spectacles aren't designed for flirting or sharing inside jokes. But they do "wink" by fogging up for a split second.
Made by Masunaga Optical of Japan, they're designed to force computer users who suffer from dry eyes to blink at regular intervals.
The Wink becomes opaque for 0.1 or 0.2 second every 10 seconds, and is targeted at people who develop eye strain by staring at computer screens all day, which would seem to be a good chunk of humanity.
