Visually-impaired people are in for some great news as Google has just published its patent for an electronic or bionic eye that can permanently correct your vision without the use of glasses or contact lenses.
Business Insider reports that the lens insertion procedure is rather intrusive and complicated. The process involves surgically removing the affected person's lens from the lens capsule of his or her eye and then injecting a fluid into it.
The fluid purportedly acts like glue that enables the surgeon to attach an intra-ocular device to the lens capsule while also creating an electronic bridge between the wearer's lens capsule and the device. This bridge is the key to the creation of bionic eye aka electronic contact lens.
The device is embedded with a sensor that lets its wearer see both distant and nearby objects or images with full clarity. The biggest advantage of implanting a bionic eye is its ability to correct vision permanently after a single surgery.
Here's is a brief extract from the patent detailing how the device works:
The electronic lens could be controlled to have a first optical power during the first period to provide images of far objects (e.g., objects more than approximately 20 centimeters away from the eye) in focus on the retina of the eye, and the electronic lens could be controlled to have a second optical power greater than the first optical power during the second period to provide images of near objects (e.g., objects approximately 9 centimeters away from the eye) in focus on the retina of the eye.
Despite the existence of such a patent, Google has not revealed if or when the electronic eye would see the light of day.
