Love it, indeed
Really good solution

This is a new option

Quote of the day

People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from sunlight.

Bionic Eyes Are Coming, and They’ll Make Us Superhuman

RATE THIS! +25
Posted in Science on 14th Nov, 2016 12:36 PM by AlexMuller

With an estimated 285 million people with visual impairment, treatments have long been in development. The panacea of restoring sight to the blind is the stuff of sci-fi: the bionic eye. A retinal prosthesis, works by bridging the gap between light entering the eye and the optic nerve, which is what communicates images to the brain.

 
So far, the only US FDA-approved device is the Argus II, from a company called Second Sight. It works using a camera integrated to a pair of eyeglasses, and an implant on the surface of the eye that taps into the optical nerve. Currently, Argus II users are capable of perceiving only shadows and outlines of figures.
 
Another up-and-coming development is Melbourne’s diamond-electrode bionic eyes that may be able to perceive facial expressions and read large prints. Scientists behind the tech are are arranging for clinical testing.
 
These bionic eye technologies don’t restore vision to a perfect level and are far from ideal, but there’s continued development that may soon get us there.
 
When we finally invent tech that restores perfect sight, what then? Beyond healing blindness, bionic eyes could potentially make us superhuman.
 
Light comes in different wavelengths and humans can only see the visible spectrum made of colored light. If a bionic eye could let us see the entire electromagnetic spectrum , from radio waves to gamma waves, we’d be able to “see” heat, identify types of gases by sight, and even look through walls.
 
We may be able to zoom in and out of our field of vision (tech that already exists), record what we see, and automatically sync it to the net with our Wi-Fi-ready eyes. It’s all speculation, but nobody can deny that innovative technology is turning science fiction into reality.
 
Bionic open up an array of applications in several fields: studying microbes could be done without equipment, soldiers can detect mines in a field, manual airport security could beef up surveillance, the possibilities are endless.
 
It may be several decades before we get bionic eyes that perfectly restore visual acuity. Until then, scientists will be keeping a sharp eye out for every development.
