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

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

The filter consists of vertical rows of tiny lenses alternatively holes. 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 respective eye of images corrected for refractive error.

We basically put 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 the adjustment works only to one user at a time. But Ramesh surprise at the MIT Media Lab points out in a press release that if the screen has a big 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 pointing to researchers the ability 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 next week at SIGGRAPH, an international trade fair for computer graphics and interactive techniques in Vancouver, Canada.
