A Japanese eyewear maker Masunaga Optical employee displays the blinking "Wink Glasses", which are supposed to help prevent dry-eye when the users concentrate on video gaming or on the Internet. The Wink Glasses, powered by button batteries or USB, have a small sensor to watch how often the user blinks and to make the lens fog when the user keeps his eye open for five seconds without blinking.(Xinhua/AFP Photo)
