Soon, you will be able to get a pair of 'smart' contact lenses as a team of scientists is creating a stretchable nano-scale device to manipulate light.
Long sightedness/Hyperopia Causes Symptoms Diagnosis Treatment FAQs
Long sightedness also known as hyperopia or farsightedness is a common vision problem. Long-sighted people have difficulty seeing near objects than distant objects.

‘Manipulation of light using stretchable nano-scale devices could be used in the future to make smart contact lenses or flexible ultra thin smartphone cameras.’
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.
Researcher Withawat Withayachumnankul said, "Manipulation of light using these artificial crystals uses precise engineering. With advanced techniques to control the properties of surfaces, they can dynamically control their filter properties, which allow them to potentially create devices for high data-rate optical communication or smart contact lenses. The current challenge is that dielectric resonators only work for specific colors, but with our flexible surface we can adjust the operation range simply by stretching it."
Lead author Philipp Gutruf said, "With this technology, we now have the ability to develop light weight wearable optical components which also allow for the creation of futuristic devices such as smart contact lenses or flexible ultra thin smartphone cameras."
