'Algae proteins' partially restore man's sight

'Algae proteins' partially restore man's sight The vision of a completely blind man has been partially restored using light-sensing proteins first found in algae.

The man was treated with a type of therapy called optogenetics, which uses the proteins to control cells at the back of his eye.

He first knew it was working when he realised he could see the painted stripes of a pedestrian crossing. BBC News
