Nano-Scale Device Manipulates Light for Contact Lenses
Phys.org. “The device manipulates light to such an extent that it can filter specific colors while still being transparent and could be used in the future to make smart contact lenses. Using the technology, high-tech lenses could one day filter harmful optical radiation without interfering with vision - or in a more advanced version, transmit data and gather live vital information or even show information like a head-up display. The light manipulation relies on creating tiny artificial crystals termed ‘dielectric resonators,’ which are a fraction of the wavelength of light - 100-200 nanometers, or over 500 times thinner than a human hair.” Read more.
