It is hard to imagine losing your sight and then being totally blind for 30 years. Doing even the simplest of tasks, such as matching your socks, becomes a daily problem to tackle.
However, there is now hope for the 25,000 people in the UK who have lost their sight through a degenerative disease called retinitis pigmentosa. A company called Second Sight have been developing bionic eyes which help to restore partial vision. Although the new technology is still undergoing trials, three people in the UK have been fitted with a ‘bionic eye’ at London’s Moorfield’s eye hospital.
