May 20, 2020 · Scientists have developed a synthetic eyeball with a curved retina made of perovskite nanowires that can detect light faster and better than a real eye. The device could be used for vision prostheses and humanoid robotics, but needs more resolution and efficiency.

A bionic eye is not the same thing as a prosthetic eye. Prosthetic eyes (also called "glass eyes" or "artificial eyes") replace the physical structure and appearance of an eye that must be removed due to trauma, pain, disfigurement or disease. Bionic eye implants, on the other hand, work inside the existing eye structures or in the brain. They are ...
In the United States, the FDA has approved just one commercially available bionic eye system. The device, called the Argus II Retinal Prosthesis System, was developed by a California-based company called Second Sight Medical Products. The Argus II has been used to restore some level of visual perception to hundreds of individuals with severe retini...
The Argus II is a two-part system: It includes a small camera that is mounted on a pair of eyeglasses and a tiny array of electrodes that is implanted in the back of the eye, on the retina. Whatever the camera sees is converted into signals that are transmitted wirelessly to the retinal implant. In response, the chip's electrodes stimulate the reti...
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. To see naturally, you'd need about a million. However, some Argus II users can function well enough to read large-...
In May 2020, Second Sight announced it had obtained additional financing to continue development of its new Orion Visual Cortical Prosthesis System. The company describes the new Orion bionic eye device as “an implanted cortical stimulation device intended to provide useful artificial vision to individuals who are blind due to a wide range of cause...
Learn how bionic eye implants work, who can benefit from them and what are their current and future challenges. Bionic eyes are not the same as prosthetic eyes, but they can restore some level of visual perception for people with retinal diseases.
May 25, 2018 · Learn about prosthetic eyes, a common treatment option for people who have lost an eye due to injury, illness, or malformation. Find out how they are made, inserted, and maintained, and what to expect before and after surgery.
May 1, 2024 · Learn how bionic eyes work, who can benefit from them, and what devices are available for vision restoration. Bionic eyes are electronic eyes that stimulate surviving retinal cells to transmit visual signals to the brain.
Mar 10, 2022 · Bionic eye technology has continued to develop and in 2021 researchers at Keck School of Medicine of USC created an advanced computer model to mimic the human retina, according to the Association...
Jun 10, 2020 · Scientists at Hong Kong University of Science and Technology have created the world's first spherical artificial eye with a 3D retina made of perovskite nanowires. The EC-Eye can achieve higher resolution, sensitivity and spectral range than human eyes, and may have applications for robots and prosthetics.
Aug 16, 2017 · Learn how visual prostheses, or bionic eyes, can provide artificial vision to visually impaired people who could previously see. Find out how they work, what recipients actually see, and what are the challenges and prospects for improving image quality.
