Tiny tech firm challenges Google to come clean on smart contact lens technologies

Google has been challenged by a small Californian tech company to update the world on its smart contact lens technology to prove its actually has the technologies it trumpeted a year ago.

EPGL, a specialist in microelectronic mechanical systems (MEMS), has patents pending in smart contact lenses including mass manufacturing of integrated electronics, autofocus and smart lens case technologies.  EPGL has yet to say what it believes to be the most potentially valuable patents but it claims to have invented solutions that will enable microelectronics to be placed into Silicone Hydrogel contact lenses without dramatically changing the manufacturing process.  This, it said, is critical for the smart contact lens to truly be marketable to the masses with comfort and efficacy.
