Scientists Have Developed A Bionic Eye That Could Give Sight To Blind People
According to BGR, a team of scientists from the US and Hong Kong has built a “bionic eye” that mimics a human eye in shape and function.
- The new prototype could one day be used to restore vision in blind individuals.
- The synthetic eye, referred to as a “biomimetic eye” by the research team, has sensors that mimic the photoreceptors found in a human eye. It consists of a “hemispherical artificial retina and an array of sensors that capture and relay a live image,” wrote BGR.
- The eye’s ability to render images is not fully developed, and in its current state “it produces a low-resolution image that is capable of rendering letters of the alphabet but more complicated images will require a higher density of sensors,” BGR continued.
However, the project has many challenges due to the complexity of the human eye.
- The way that eyes communicate with the brain means that implanting it is not going to be simple, and BGR wrote that “getting a device to interface with the human brain is a huge hurdle.”
- In addition, it was difficult for the researchers to fit the technology into a spherical shape, and testing the device on a living creature will present its own complications.
The researchers are already setting up both animal and human trials, but there is still a lot of work to be done.
