Prototype contact lenses

Made in his Seattle laboratory, Babak Parviz has created new contact lenses which contain electronic circuits planning to add small LED to them and turn them into personal display screens the tinniest possible. Parviz is an assistant professor of electrical engineering at the University of Washington He makes tiny but functional electronic devices and, using nanotechnology and micro fabrication techniques, integrates them on to polymers or glass using a process known as self-assembly.
