Novartis has patented a contact lens capable of automatically focusing on objects

The invention uses sensors that pick up electrical signals from the ciliary muscle of the eye responsible for focusing. The signals are then used to control electro-active optics such as liquid crystals deposited on the contact lens. The optical power of the contact lens is thus adapted according to the viewing intention of the wearer to focus on near objects or far objects. The contact lens can also switch between near and far field vision based on a cue provided by the wearer such as a blinking pattern of the eye.PatentYogi_US9226818
