Bionic Eye Essay

Abstract-India is now home to the world’s largest number of

blind people. In 37 million people across the globe 15 million

blind people are from India. 75% of these are cases of

avoidable blindness. On the other hand, while India needs 2.5

lakh donated eyes every year, the country 's 109 eye banks in

which 5 located in Delhi manage to collect a maximum of just

25,000 eyes, 30% of which can 't be used. Meanwhile, shortage

of donated eyes is becoming a huge problem. In 15 million

blind people in India, three million that is 26% of whom are

children who suffer due to corneal disorders. But only 10,000

corneal transplants are being done every year because of

shortage of donated eye. The bionic eye aims to restore basic

visual

II.THE BIONIC EYE

It is an artificial eye which provokes visual sensations in the

brain by directly stimulating different parts of the optic nerve.

Retinal implants can partially restore the vision of people

with particular blindness caused by diseases such as macular

degeneration or retinitis pigmentosa. Bionic eye consist of

electronic systems which consist of image sensors, processors,

receivers, radio transmitters and retinal chips. There are also

other experimental implants that can stimulate the ganglia

cells on the retina or the visual cortex of the brain itself.

It comprises a computer chip which is kept in the back of the

individual 's eye, linked up using mini video camera built into

glasses that they wear Images captured by the camera are

beamed to the chip, which translates them into impulses that

the brain can interpret. Although the images produced by the

artificial eye were far from perfect, they could be clear

enough to allow someone who is otherwise blind to recognize

faces. The breakthrough is likely to benefit patients with the

most common cause of blindness, macular degeneration,

which affects 500,000 people. This occurs when there
