Progress Towards Artifical Eyes

I'm going to go out on a limb and predict, from progress in the past few years, that regenerative medicine for age-related blindness will be practical and effective before artificial eyes arrive on the scene. Which is not to say that the present state of bionic vision is bad: extremely limited vision is far, far better than no vision, and this technology will only get better with time. From COSMOS Magazine: "Early tests of a 'bionic eye' developed by Australian researchers have successfully stimulated limited visual sensation in people suffering a rare form of genetic blindness. ... the prototype bionic eye was a low-risk device for patients because it sat on the eye's surface and did not require invasive surgery. He said it was an exciting development for people suffering conditions such as retinitis pigmentosa, an irreversible genetic condition where the retina's cells gradually die but the optic nerve survives."
