I worked for a company related with Carl Zeiss Meditec, it's division from Carl Zeiss where all the human eye healthcare, treatments, studies and equipments are developed for Carl Zeiss, one of the things everybody was speaking is that there are a lot of opportunities to improve how the sight problems are treated, but there just a little investment on that because the people just want to see a little better and is willing to wear glasses and the amount of blind people is too little to make the market profitable.
I don't think the big fishes are working on it, but maybe some university or some little companies may be working on it already, there is kind of easy to electrically produce color in the optic nerve, so if the problem is with something related to the retine there is a chance, but if the problem is inside the brain I don't think we will see that in our lives.
