Bionic Eye: No Battery Required

It is common knowledge that bionic eyes receive power from batteries. The existing technology and setup when it comes to bionic eyes dictate the use of wires and battery. However, scientists at Stanford University have invented a new subretinal implant that provides power through infra red beams and electrically stimulates neurons.

Various age related problems such as macular degeneration and retinal pigmentosa cause the death of cells which detect light in the eye. Ultimately, this leads to blindness.

In modern days, retinal implants have given the ability to some patients to see again. However, the chip that is installed behind the retina requires power from a battery that’s installed behind the ear, and wires that connect the two. The implant invented by scientists at Stanford has eliminated the need to have this complex wiring arrangement. The new setup requires the user to wear a pair of glasses that is fitted with a camera. The camera records everything and sends infrared beams to the chip behind the retina. This in turn creates electrical signals which is then passed on to the nerves, ultimately allowing the person to detect motion, perceive light, and identify basic shapes.

Since the chip is very thin, and the setup is totally wireless, the surgery required is very simple. This implant has not been tested on humans yet. However, it has been successfully tested on rats.

  1. They should produce more Bionic Eye and make it available worldwide. I would like to see some of this in eye center Philippines so that people with eye conditions who can’t afford expensive eye transplant will be able to see again using that product.

  2. It would be great if this will be affordable. This is a really great invention because it doesn’t need batteries so it will not be a burden to the user.

  3. I hope that more scientists can create more products that don’t require any battery. I am just happy that there is now a Bionic Eye because lots of people who have eye problems are really spending too much money for surgery.

  4. I'm sure that the Bionic Eye will be very expensive once it is out in the market. But the truth of the matter is that, even if it is expensive, people with eye problems will still be buying it.

  5. Thank you for your comment. The Argus II, which has been approved by the FDA, costs $150,000 but the manufacturer hopes that the cost would be covered by insurance soon!
