Researchers at MIT and the University of California at Berkeley have unveiled an ingenious new display technology that eliminates the need to wear prescription glasses to properly view the images projected on these special screens.
The technology uses a clear plastic screen overlay perforated with thousands of tiny holes 75 micrometers each and spaced 390 micrometers apart in tandem with an algorithm based on the user’s prescription glasses.
The algorithm adjusts the light from each individual pixel, so when it passes through the perforated screen the light reaches the eye as a clear image.
This technology corrects nearsightedness, farsightedness, and astigmatism. After performing additional experiments, researchers also discovered that their algorithm was able to help individuals whose visual impairment cannot otherwise be improved using glasses.
One of the goals of this technology is to develop displays that can be viewed simultaneously by multiple users with different prescriptions. Also, as vision correction displays are an offshoot of glass-less 3D screens, new user interfaces and next generation virtual reality are avenues of research development that will be followed.
Best of all, visual correction displays will help hundreds of millions of people use their tablets, smartphones and computers in a refreshing new way, without glasses.
