Get sleepy at work? Need to stay awake and get things done? Well, there's another way to help you burn the midnight oil (or just stave off that post-lunch afternoon drowsiness) with the Masunaga Wink Glasses, now available again and finally here for overseas shipping. These clever specs can detect when you haven't blinked in five seconds and fog up one of the lens.
This simple function will then "jolt" the eyes and make them focus, thus waking you up before you drop off fully. Men blink once every three seconds; women once every four seconds. So any longer than this and you are slowing down, which generally means you are getting sleepy. Don't let yourself fall asleep at your desk again! This set of glasses and frames is compact and lightweight, and powered by a USB and/or battery that can go for eight hours
