285 million people around the world live with irreversible vision loss.
However, dozens of research groups are working on bionic eye technologies
that might one day restore vision to people who are blind.
Restoring a functional level of vision to people living with vision loss has been a dream of medicine for centuries. Although we are still far from restoration of high-resolution vision, bionic eye technologies are overcoming crucial bottlenecks and are slowly moving from the laboratory into the clinic.
In combination with cell implants, gene therapy, and optogenetics, a wide variety of sight restotation technologies should be available in the near future.
