Goodbye, Glasses: Future Smartphone Screens Could Correct Vision
Say goodbye to glasses. A new high-tech smartphone accessory can bring images on your device’s screen into focus without a trip to the eye doctor.
This “vision-correcting display” is a thin, transparent material that fits on top of the screen of a smartphone or other device. It works in conjunction with a software program to correct the viewer’s focal distance — the range at which the eye can bring objects into focus.
People with visual impairments, such as nearsightedness and farsightedness, have trouble with focal distance, said Gordon Wetzstein, a research scientist at the Massachusetts Institute of Technology’s Media Lab who helped develop the new display technology.
