For our course “Introduction in Microelectronics” MSc student Lucas van Dijk wrote an inspiring essay about how you can either restore vision for the blind or create enhanced vision for people that see normally.
The essay can be found here.
The abstract reads: “The current state of visual prostheses progresses rapidly. In this essay three approaches to a visual prosthesis are discussed: an epiretinal implant, a visual prosthesis which stimulates the optic nerve, and a visual prosthesis which stimulates the lateral geniculate nucleus. While the epiretinal implants are currently the most advanced visual prostheses available, I think
a visual prosthesis stimulating the lateral geniculate nucleus has the greatest potential, especially when you also keep applications for people with healthy vision.”
