Today New iPhone app could delay need for reading glasses

GlassesOff, to be launched on the iPhone next year, could allow people to keep reading as normal beyond the age where they could otherwise have needed glasses, its developers said.
It works by training the mind to translate blurry images into clear ones, to compensate for the deterioration of the eyes which prevents us focusing on nearby objects.
Uri Polat, of Tel Aviv University in Israel and co-founder of Ucansi, the company which designed the software, told the New Scientist magazine: "We're using the brain as glasses."
When we reach our fifties the lenses in our eyes to become less supple, meaning it is harder for them to focus on objects that are close to us.
In the new app, groups of blurry lines known as Gabor patches appear at several points across the screen and the user must identify when one appears in the centre.
