Engadgeteers spend a lot of their day staring at a screen, so it's no surprise that nearly all of us are blind without glasses or contact lenses. But wouldn't it be great if we could give our eyes a break and just stare at the screen without the aid of corrective lenses? That's the idea behind an experimental display that automatically adjusts itself to compensate for your lack of ocular prowess, enabling you to sit back and relax without eyewear. It works by placing a light-filtering screen in front of a regular LCD display that breaks down the picture in such a way that, when it reaches your eye, the light rays are reconstructed as a sharp image. The prototype and lots more details about the method will be shown off at SIGGRAPH next month, after which, its creators, a team from Berkeley, MIT and Microsoft, plan to develop a version that'll work in the home and, further down the line, with more than one person at a time.
