read about bionic vision yesterday.. it is much closer to my aim i.e to have a fully submersive, partially submersive and augmented reality vision... basically bionic vision is acheived by building the electronic circuitry and place miniature LEDs on the surface of a contact lens. it is a highly miniature device that is devised using nano fabrication techniques like self - assembly.

it is a sophisticated device alright, but first i would proceed with my vrd device.. but i know someday, in course f my project i'll have to work with bionic vision.
this new concept is very exciting..!
