Artificial lens mimics the human eye

Researchers have created a new artificial lens, made up of thousands of nanoscale polymer layers, that's almost identical to the lens in a human eye.

Team produces weird optical phenomena - and rewrites the rules of refraction

Researchers at the Harvard School of Engineering and Applied Sciences (SEAS) have induced light rays to behave in a way that defies the laws of reflection and refraction, while producing some weird fun-house images on the way.
