Imagine wearing a contact lens that lets you zoom in on distant objects or surf the web without a computer monitor. Sounds like science fiction, right?
Engineers at the University of Washington have combined a flexible, biologically safe contact lens with an imprinted electronic circuit and lights in what may be the first step to making that science fiction into reality.
The contacts don’t actually do anything yet, but their testing shows that the contacts are safe to wear and they don’t obstruct vision. Eventually, researchers hope to add some sort of display, as well as wireless communication to and from the lens. The whole thing will be powered by a combination of radio-frequency power and solar cells placed on the lens.
