A microfluidic strain sensing device for monitoring intraocular pressure. The device has a contact lens and a closed microfluidic network embedded with the contact lens. The network has a volume that is sensitive to an applied strain. The network distinguishes: (i) a gas reservoir containing a gas, (ii) a liquid reservoir containing a liquid that changes volume when the strain is applied, and (iii) a sensing channel able to hold the liquid within the sensing channel. The sensing channel connects the gas reservoir on one end and connects the liquid reservoir on another end. The sensing channel establishes a liquid-gas equilibrium pressure interface and equilibrium within the sensing channel, which would fluidically change as a response to radius of curvature variations on a cornea, or as a response to mechanical stretching and release of the cornea. The liquid-gas equilibrium pressure interface and equilibrium are used for measuring the intraocular pressure.

Closed microfluidic network for strain sensing embedded in a contact lens to monitor intraocular pressure

A contact lens with a sensor region are described. The contact allows for normal vision and a concentric ring around the vision area of the lens includes one or more sensors for detecting changes in the interocular pressure of the eye. The data may be scanned using a camera, or in some embodiments, the data may be transmitted using a micro antenna in the sensing region. The data may be analyzed using a software application on a cell phone or other computing device.

Method and device for wearable contact lenses for remote optical monitoring of intraocular pressure

A wearable eyewear device, methods of use and systems are described that allow a person wearing the eyewear device to accurately measure the intraocular pressure of their eye, and dispense a medication to the eye when needed.
