A patent filed in April 2015 by Google aims to revolutionise human beings’ sight by developing liquid contact lenses that are designed to be injected directly into a lens capsule of the eye.  The goal of these contact lenses is to improve the eyesight of people who are suffering from decreased focus and degradation of images.

The patent states: “An intra-ocular device includes an electronic lens that can be controlled to control the overall optical power of the device. The device can be installed within a flexible polymeric material shaped to conform to the inside surface of a lens capsule of an eye”.
