New Display Technology Could Free People from Wearing Eyeglasses

Using a laptop or watching TV can be more enjoyable without wearing glasses.

There's a new display technology that corrects vision problems. It uses algorithms to change an image based on an individual's glasses perception.

The algorithm also changes the light from each individual pixel that let rays of light reach the retina and re-create sharp images.

According to researchers, the idea of display technology is to foresee how the eyes naturally deform whatever is on the screen and then adjust it for clearer image. It works with a clear plastic light filter packed with thousands of tiny holes that is attached to the front of a display like personal computer.

Brian Barsky, computer science professor and affiliate professor of optometry and vision science at University of California and co-author the paper, said that display technology is undoing what the optics in the eyes are about to do.

Developing this display technology is taking place in collaboration with researchers at the Massachusetts Institute of Technology and Microsoft.

Researchers say it also aims to help people with serious vision problems due to physical defects that can't be cured with glasses and contact lenses. One of the physical eye defects researchers want to correct is the spherical aberration that refracts light differently in the lens.

This is not the first attempt to create a method of correcting vision, however. This new display technology produces a higher-contrast and sharper images.

The team of researchers led by Barsky will present the research paper at the annual International Conference and Exhibition on Computer Graphics and Interactive Techniques (Siggraph) in Canada in August.

They are now working on the prototype to be tested by people viweing different types of screens.

Researchers expect the display technology to be ready in the next few years.
