People with the most common form of sight loss could regain their vision with a new contact lens that has an in-built telescope.
The lens, which could help 500,000 British sufferers of age-related macular degeneration (AMD), increases peripheral vision three-fold. It could be available in two years and is safer and cheaper than surgery, Swiss scientists say.
The lens works in conjunction with glasses and is activated by winking. The user winks with their right eye which triggers the lens to zoom in. They wink with their left to turn off the telescope.
AMD is the biggest cause of sight loss in Britain with sufferers losing their ability to see in the centre of their field of vision, making it difficult to read and recognise faces.
