Finally, a Contact Lens That Actually Beams Lasers From Your Eyes

Scientists have created an ultrathin, flexible film that can emit laser light — and successfully tested it on a contact lens, demonstrating the possibility of laser eye-beams.

Before you rush out and buy a Cyclops-style visor, it’s not even close to powerful enough to cause damage. Instead, the researchers say, the technology has potential for use as wearable security tags, or even as a type of laser barcode.

The membranes containing the material are less than a thousandth of a millimetre thick, and flexible, which means they can easily be stuck to, or embedded into, polymer banknotes, or the soft plastics used for flexible contact lenses.
