Engineers create an artificial eye that restores vision to the blind!

This good news for the blind must have surprised you, as well as us.

Researchers at the University of Minnesota have designed a prototype of a biological eye that can restore vision to blind patients and give them high-definition vision, especially for visually impaired people. The researchers used a specially designed 3D printer to build a prototype of experimental biological eyes.

The start of the experiment

The engineers printed a base of silver particles inside a spherical dome of glass and then used semi-finished polymeric materials to print controls (photodiodes) and devices that convert light into electrical signals, which are located on top of the silver base.

The whole process took an hour, then the team obtained an experimental biological polymer eye that could convert light into electricity with an efficiency of 25%.

The blind patient will not feel it as large because it will be in the eye socket.

So the researchers and developers of this eye are trying to figure out a way to print on a smooth hemispherical material, and they also want to add more photoreceptors to increase its efficiency.

The opinion of the team developing this prosthetic eye

The inventor of the prosthetic eye indicated that this model is an important step in the right path towards making biological eyes suitable for human use.

Where it appeared to researchers that semiconductors printed with 3D printing technology are very effective even those used in devices produced in small manufacturing laboratories.

Researchers in these high-tech laboratories used sophisticated equipment for very small engineering scales to arrive at this result.

3D printing prospects

A 3D printer can do very fine things like this prosthetic eye.

Therefore, many researchers have begun to work on their own inventions and use semiconductors regardless of whether they have access to these advanced laboratories or not, and recently a method for printing semiconductors on a curved surface has been revealed, which strengthens hope for this promising technology.

A better view for all blind people

Creator McCallin decided to make a biological eye because his mother suffers from vision loss and cannot see into one of her eyes.

However, this innovation will benefit many people who have eyesight and vision problems, and the mother of the innovator will not be the only one to benefit from this device, but on the contrary, because biological eyes can ultimately improve anyone's vision.

It must be noted that the damaged natural eyes must be removed from their place to implant biological eyes in their place so that the affected person can look through them.

The engineers developing this technology will need to exert effort to find out how they can convert electrical signals from the eyes into a signal that the brain can interpret, and this may take time.
