Electronic eyes bring light to the blind

A blind man in England once thought he might never be able to see the light again, but now under the help of electronic eyes, his eyesight is being restored.

Peter Lane, 51, is the father of two children. When he was 20, he suffered from retinitis pigmentosa, eyesight began to decline, eventually blinded completely.

In early 2009, Peter Lane underwent a four-hour operation at Manchester Eye Hospital, doctors transplanted a signal receiver into his eye. After two months of recovery, Peter Lane began trying to use electronic eyes. Earlier this month, everything gradually appeared before his eyes.

'I see images that move, slowly adapt. But I saw cars, they looked like cotton blankets, " Peter Lane said.

Peter Lane and the electronic eye.

Peter Lane can distinguish simple words on the projector screen, 'after experiencing a dark time, the feeling of seeing the letters on the screen is amazing.'

This electronic eye is made up of a camera, image processing chip and some other parts. When the electronic eye operates, the camera mounted on the glass will capture the image, then transfer it to the image processing chip on the user into electronic signals. These signals are transmitted by the transmitter to the signal receiver and electrode plate mounted on the retina. The electrodes are responsible for activating the retinal nerve, sending signals to the brain, through which the brain reproduces the images obtained, helping the blind to see things in the world.

'I can still do some normal things when I'm at home, because I already know the location of the objects in the house, but when I go out, this glass has really brought self Believe me, I can do some other things myself, 'said Peter Lane.

Currently, there are only 11 doctors in the world who have mastered the techniques related to this technology. Peter Lane is one of 32 participants in an electronic eye test. Other patients who participated in the trial, such as Peter Lane, had positive results; in which one blind man after 40 years saw the fire, and the other can also distinguish the letters.

Paulo Stangaat, an eye specialist at the hospital, said: 'The patient recovered so quickly that beyond our imagination. Although there is much work to be done, the current results really bring hope to find the light for the blind in the near future '.
