This prototype display could render reading glasses obsolete

Internet users 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.
