Those of us who need glasses to see a TV or laptop screen clearly could ditch the eyewear thanks to a display technology that corrects vision problems.
The technology uses algorithms to alter an image based on a person’s glasses prescription together with a light filter set in front of the display. The algorithm alters the light from each individual pixel so that, when fed through a tiny hole in the plastic filter, rays of light reach the retina in a way that re-creates a sharp image. Researchers say the idea is to anticipate how your eyes will naturally distort whatever’s onscreen—something glasses or contacts typically correct—and adjust it beforehand so that what you see appears clear.
