Mark.. is this for real? I wear contacts, but if there's the tiniest speck on one of my lenses it looks like a giant annoying balloon to my eye, so how would this work?
The contact lenses are more an early development thing, rather than having any real use. I think it only has 1 pixel which is wirelessly powered. But creating a full display at that size should be possible - nanotechnology is incredible and we are lucky to live in the age of its mass commercialisation
