Scientists restore partial sight in blind man

Botond Roska, from the Institute of Molecular and Clinical Ophthalmology Basel, said that the patient was initially frustrated as he could not perceive objects even after months of training with the goggles.

"And then spontaneously, be started to get very excited, reporting that he was able to see and getting very excited about this achievement," said Roska, who co-authored the study published in the journal Nature Research Journals.

This is a very important detail, for many reasons (mostly related to funding) many research protocols and clinical trials are very limited in time, which mean that therapies that could have lead to very positive developments are abandoned after a short time because of lack of results. Fortunately in this case they could continue even after a very disappointing beginning and the patient got a huge benefit from it.

Really exciting research that will hopefully benefit many people in the future, but probably not cheap either, sadly.

Would be interesting to see how it would work for somebody born blind, but I would guess not at all without the kind of neuron development required from an early age.

This is cheering news. Both blindness and deafness can be devastating. I don't know which would be worse, when you are blind you have lost "things" but deafness causes you to lose "people."
