Do you need glasses when working with your computer, or use the cell phone? Forget it. U.S. scientists have developed a technique where synfelet corrected directly on the screen.

Närsynhet, astigmatism, presbyopia or farsightedness. All are the vision problems that can be corrected directly in the computer. Say researchers from the U.S. MIT Media Lab. The researchers have 3d technology to help to create images that reach each eye in a form that makes them instantly becomes sharp for our brain. The condition is partly a filter that sits in front of the screen, and an algorithm where the refractive error is inserted.

The filter consists of vertical rows of tiny lenses alternatively hole. Through them reach different pictures right and left eye. The brain then puts together the image to a single image. The technique is similar to that used to create 3D images without glasses. The difference is that here reached each eye of images corrected for refractive error.

-We put basically the glasses on the screen instead of on the nose, says Gordon Wetzstein, a researcher at the MIT Media Lab and one of the creators of technology .

With this method, the researchers also say they have corrected vision problems that can not be corrected with glasses.

So far, work adjustment only to one user at a time. But Ramesh surprises at the MIT Media Lab points out in a press release that if the screen has a large enough resolution you can make it work for multiple simultaneous users. The tests have been done so far with a prototype for mobile phones. In addition to regular computers and reading frames, the researchers point to the possibility to customize everything from watches to GPS screen in the car. The group has also developed a technique that measures synfelet of the person looking directly at the screen.

The technique presented in the next week at Siggraph, an international trade fair for computer graphics and interactive techniques in Vancouver, Canada.
