The loss of sight can be caused by a multitude of reasons. In many cases, sight deteriorates when we grow older and the muscles in our eyes become a little weaker, bat it can also be due to diabetes, cataract, and of course, accidents or injuries. So far, prosthetic eyes have developed in terms of material and lifelike design, but new technological development is the best attempt ever made to mimic the human eye.
So how did they do it?
This new prosthetic eyeball was born through the collaborative efforts of engineers from the US and Hong Kong. They used the human retina as a model and tried to create something that would best resemble it, right down to its dome-like structure of it. Their work process started with the creation of high-density photoreceptors which were then set in the pores of aluminum oxide. Then, they had to create the nerves for the new eye. For that, they created micro-wires from liquid metal that was poured into rubber tubes and installed the whole system in the artificial eyeball. Looking at the eye from the outside will have you thinking it is human, but the inside of it is completely bionic! This new technology is able to restore up to %80 percent of the sight of a person in need of a prosthetic eye.
