The Japanese company that designed Sarah Palin's thin-rimmed specs has released a new set of glasses to fight "dry eye." The condition affects gamers, readers and others who stare at screens or pages for long stretches of time, causing a lower than average blinking rate.

Masunaga Optical Manufacturing Co.'s new Wink Glasses feature a tiny sensor that monitors the wearer's eye-blink activity. If the users' eyes go more than five seconds without blinking, tiny liquid crystals cause the lenses to become opaque, fogging vision. The wearer is forced to blink, after which the lenses immediately de-frost.

The high-tech glasses protect customers' eyes from fatigue and dehydration. But, they're not cheap, be ready to shell out $430.
