Amazing!! Stimulation Of The Optic Nerve Has Been A New Aid For The Blinds!
Researches say that the scientists have been finding ways to provide visual signals to the blinds by directly stimulating the optic nerve. Scientists from EPFL in Switzerland and Scuola Superiore Sant'Anna in Italy are developing technology for the blind that bypasses the eyeball entirely and sends messages to the brain. They do this by stimulating the optic nerve with a new type of intraneural electrode called OpticSELINE. Successfully tested in rabbits, they report their results in Nature Biomedical Engineering.
Blindness affects an estimated 39 million people in the world. Many factors can induce blindness, like genetics, retinal detachment, trauma, stroke in the visual cortex, glaucoma, cataract, inflammation or infection. Some blindness is temporary and can be treated medically. How do you help someone who is permanently blind?
Well, there is a solution to it! We can bring about change and provide visually impaired people!
Retinal implants, a prosthetic device for helping the blind, suffer from exclusion criteria. For example,
