Google patents contact lens that switches focus to fight nearsightedness

Patent drawing
Patent drawing from the official filing.

This filing describes a contact lens made of breathable material that contains electronic parts and light-changing elements. It uses a small circuit to switch the lens's focus on and off, sending specific visual signals to the side of the eye to slow down the physical elongation that causes nearsightedness.

Why it mattersIt offers a potential new way to manage a common eye condition using wearable technology rather than just standard corrective lenses.

In the filing’s own words

A lens device that can be placed on a patient's eye for treating and/or preventing myopia. The lens device includes a body comprising a gas-permeable material that can at least partially encompass one or more adaptive optical elements and an electrical circuit and/or actuator. The adaptive optical elements can switch between an optical state and at least another state when the electrical circuit and/or actuator cases the switch based on a control signal. The adaptive optical elements switch between the optical state at a time and the at least the other optical state at another time for a time period to present visual stimuli to a peripheral retina to slow axial growth of the eye in order to treat and/or prevent myopia.

What exactly they claim (claim 1)

1. A lens device configured to be placed on a patient's eye for treating and/or preventing myopia, the lens device comprises: a body comprising a gas-permeable material; one or more adaptive optical elements embedded in the gas-permeable material and each of the one or more adaptive optical elements configured to switch between an optical state and at least another optical state; and an electrical circuit and/or actuator configured to cause one or more adaptive optical elements to switch between the optical state and the at least the other optical state based on a control signal, wherein the one or more adaptive optical elements switch between the optical state at a time and the at least the other optical state at another time for a time period to present visual stimuli to a peripheral retina to slow axial growth of the eye.
