In an age where reading something from a screen on a phone or a computer is a normal part of our daily lives, the wearing of glasses or contact lenses often makes doing so a chore with eye-strain problems and the necessity to carry around spectacles or lenses wherever you go. In this vein, researchers at the University of California at Berkeley have created a prototype vision-correcting, printed pinhole matrix that they claim fits directly to a screen and negates the need for eyeglasses or remedial lenses and may one day offer improved visual acuity to those with eye problems much worse than simple farsightedness.
