    We've known the power of meta-material structures for decades but are just now becoming able to create visible spectrum practical devices.

    Excellent! I am eager to get my next pair of glasses without the lenses being thicker than 5mm.
    Where should I send the prescription?

    At the bottom of the article it notes that they previously worked with infrared, so that might be were that figure comes from. You can always count on a reporter to get the facts wrong.
