An application which promises to help improve vision by training the brain, may be available for download from computers and iPhones next year.
U.S. firm Ucansi claims that GlassesOff application will give middle-aged people the eyesight of those 10 years younger to them and that it can dramatically reduce the need to wear reading glasses.
According to New Scientist, trials of the GlassesOff software have produced startling results, with people being able to read more than two lines further down an eye chart after training and reducing the time taken to read a newspaper page by more than half.
GlassesOff - an application to combat presbyopia, which is expected to be launched early next year, will initially be a smartphone app, whereas a version for home computers could follow.
People using the application are first shown a grey screen containing a white circle and then a number of images in quick succession at various places on the screen, out of which some are blank, while others contain blurred patterns of lines, known as Gabor patches.
The aim of the exercise is to pick out any of the Gabor patches that fall in the same place as the white circle, with the task getting faster and more difficult as the user gets better at it.
"We're using the brain as glasses. Every single change is in the brain," the Daily mail quoted Uri Polat, co-founder of Ucansi as saying.
