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.

So-called computer vision syndrome can cause a range of temporary symptoms from headache to dry eyes to double vision.

Designed by industrial designer Kazuo Kawasaki, the Wink glasses look normal enough, but they weigh slightly more than regular eyeglasses. The lenses are covered with liquid crystal sheets, and there's a small battery in the left arm.

When the glasses are in fogging mode, activated by a small button on the right arm, the battery's weak electrical current in the liquid crystal sheets gets cut off, momentarily fogging them and inducing a reflexive blink.

The Wink Glasses 2013 simplifies an earlier model that had an internal blink sensor which would trigger the fog; it had to be calibrated for individual users.

The latest iteration sells for about $150 in Japan, and can be fitted with prescription lenses for extra. IT companies and ophthalmologists have been ordering them, according to The Asashi Shimbun newspaper.
