The battle for your face is on!
On Thursday night, Google announced that it is working on  a “smart contact lens,” which is meant to be worn by diabetics and  which would use small sensors to measure the wearer’s glucose levels.
Google’s Contact — or “EyeGoogle,”  as I’m calling it — isn’t the Silicon Valley giant’s first foray into  wearable face-computing: Google Glass, the company’s head-mounted  smartphone assistant, is slated for a wide release in 2014; nor is  Google the only technology company working hard to get you to stick a  computer in front of your eyes in the coming years.
Here are the most important companies working on wearable facial  computers. If any of these companies have their way, we’ll all have  little screens plastered on our noggins by New Year’s 2015. These are  the ones you should keep an eye out for.
1. Google
In the past year, Google has certainly established itself as the  company people most associate with whimsical, futuristic face computers,  with its forthcoming Google Glass and still-several-years-away smart contact lens. 
Important to note: Though glasses and contact lenses perform similar  functions in normal life, Google Glass and Google Contact Lens do not.  Google Glass is what you might consider a more traditional wearable  computer (if such a thing exists): It simply performs several of your  smartphone’s functions on a small screen in front of your eye — showing  you text messages, the time and weather, walking directions — so that  you don’t have to pull your phone out of your pocket. Google’s contact  lenses, meanwhile, has a more specialized function: Intended for  diabetics, it measures your body’s glucose level in the eye so that you  wouldn’t have to prick yourself for a blood sample several times per  day.
With contact lenses and eyeglasses covered, it’s only a matter of  time before Google introduces computerized binoculars, opera glasses and  monocles. Stay tuned
2. Oculus VR
For decades now, playing video games at home has usually meant  staring at a screen — either several feet away from your eyes, with  video game consoles, or about a foot away from your eyes, with computer  games.
The Oculus Rift,  created by a startup called Oculus VR, is a buzzy new system that  brings the screen right up against your face. Still in prototype mode,  the Rift itself is a sort of visor that completely blocks out your  vision, except for a high-definition screen in front of your eyes that  hooks up to a computer game. Your point-of-view is your game character’s  point-of-view; and the system also tracks your head movements, so that  wherever you look, that’s where your character in the game looks, too.
