This contact lens is laced with sensors that track your eyeball movement. It communicates your eyeball's tracking info to a receiver connected to your computer, like a wireless mouse.
If you think about it, when you look at your screen, your eye must see something first before you can click on it. In other words, this should be way faster than a real mouse.
Come on, try it: Look on the left of your screen and then on the right of your screen. Your finger is naturally behind in speed. With these cyborg contact lenses, blinking your eye translates into a click. This device was originally made for disabled people, but it is super cool for anyone wanting to be like Tom Cruise in 'Mission Impossible.'
