Can bionic eyes cure blindness?

TEHRAN (Tasnim) – A team of researchers has built a bionic device that they say can restore vision to the blind through a brain implant. It has been more than 10 years in the making, but scientists are preparing to implant a ‘bionic eye’ in a human subject.

How successful is the bionic eye?

The successful development of a bionic eye has the potential to change lives in a very real, very hands-on way. Restoring even basic sight to those with impaired vision may allow them to become more mobile and independent, and return to them some of the quality of life they lost when their vision disappeared.

Is there such a thing as a bionic eye?

A bionic eye, otherwise known as a visual prosthesis, is an experimental device that’s intended to help restore sight for people who are visually impaired.

How does electrode panel for bionic eye work?

The electrode panel gives out pulses which reaches the optic nerve to the brain, also in case of a damaged optic nerve the signals can be easily sent with the use of other specialized devices. Just when the brain gets the signals, the brain starts processing accordingly letting the blind person see.

Where are the sensors in the bionic eye?

Those sensors reside within a membrane made of aluminum and tungsten which is shaped into a half sphere for the purpose of mimicking a human retina. The retina is the eye’s innermost layer of tissue, which translates images into electrical neural impulses to the brain in order to create visual perception.

Are there any limitations to bionic eye implants?

Limitations Of Bionic Eyes. Although the Argus II system enables people to discern light, movement and shapes, it does not yet restore sight to the extent some might hope. This limitation is largely due to the fact that the current implant has only 60 electrodes.
