Engineers from the University of Washington used manufacturing techniques at microscopic scales to combine a flexible, biologically safe contact lens with an imprinted electronic circuit and lights.
Virtual displays have been proposed for many practical purposes — visual aids to help vision-impaired people, holographic driving control panels and even as a way to surf the Web on the go.
“Looking through a completed lens, you would see what the display is generating superimposed on the world outside,” said Babak Parviz, a UW assistant professor of electrical engineering. “This is a very small step toward that goal, but I think it’s extremely promising.”
