I know, you play Call of Duty SO COMPETITIVELY that you can't even blink. But since that mentality leads to eyestrain (which leads to fewer kills), Japan's Masunaga Optical Manufacturing has invented Wink Glasses.
The glasses implement a sensor that constantly tracks how often you blink. Go just five seconds without blinking your eyes and, BAM,
the lens fogs over your right eye until you blink again.
