Sight loss reversed by 'nanoflowers'?

People who may use assisted living due to sight loss could be helped to see again thanks to a new technology.

Richard Taylor, of the University of Oregon, is attempting to grow 'nanoflowers' which could help those with macular degeneration to regain their sight.

The nano-sized particles, or fractals, self assemble during a natural process. These could then be implanted into the eyes of blind patients, according to the article in Physics World.

It is thought the device would collect the light captured by the retina and transfer it to the neurons for relay to the optic nerve, which would process vision.

Mr Taylor said: "We're right at the start of this amazing voyage.

"The ultimate thrill for me will be to go to a blind person and say, we're developing a chip that one day will help you see again."

Meanwhile, those looking to keep their eyes healthy should make sure they are eating plenty of green vegetables, oily fish, eggs and pistachio nuts, according to one expert.

University of Miami Miller School of Medicine researcher Sheah Rarback told the Miami Herald that these foods, which contain plant molecules lutein and zeaxanthin, could improve vision.
