Wink Glasses is made by Masunaga Optical Manufacturing. This Japanese optical company makes them. Wink Glasses are equipped with sensors that measure how long you have been staring at a screen without blinking.

Once the sensor has been triggered, and it knows that you need to blink, the Wink Glasses fog up the correct lenses. You will lose your vision until you blink. This occurs every five seconds and prevents eye strain. Eye strain is one of the most common health problems in America. 59% have reported symptoms.
