Sometimes geeks sit in front of computer screens for a really long time, and we forget to do stuff like eat food, drink water, and blink our eyes. That’s why Masunaga, the company that designed Sarah Palin’s glasses, is coming out with a new product called Wink Glasses on August 10th. A sensor attached to the lenses detects blinking movements; if it doesn’t log any activity for five seconds, an ultra-thin liquid crystal sheet pasted onto the lens surface fogs up and doesn’t clear up until you blink again. The sensor is operated by a battery rechargeable via USB &mdash I guess that means that if you don’t charge them, they don’t fog up. The frame and sensor set will cost about $400.
