A shunt valve for removing biofluid from an eye of a user, the valve including a tubular body defining an inlet and a plurality of outlets formed through a wall of the tubular body; a plunger accommodated within the tubular body and fluidically coupled to the inlet; wherein the plunger is movable relative to the plurality of outlets; and an energized material coupled to the plunger and the tubular body; wherein the energized material is compressible to expose a portion of the plurality of outlets dependent on the pressure applied to the energized material.

A device for non-invasive monitoring and measuring of intraocular pressure (IOP) of a subject includes a flexible lens that fits on the eye and changes curvature in response to a change in curvature of the eye. A microchannel disposed in or on the lens has one or more ends that are open to the atmosphere and an indicator solution is disposed in a portion of the 5 microchannel. The microchannel exhibits a change in volume in response to a change in curvature of the lens, which results in a change in position of the indicator solution in the microchannel. The change in position of the indicator solution in the microchannel is indicative of a change in IOP. The change in position of the indicator solution may be detected in digital images of the lens taken with a camera of a mobile electronic device such 0 as a smartphone or a camera worn by the subject.

A portable device, method and system are provided for automated, quantitative assessment of orbital compliance and soft tissue restriction with emphasis on applicability to orbital trauma and fracture management is provided.

A faceguard is configured for measuring a human eye muscle movement response. The faceguard is configured for protecting at least one part of a human face and has an aperture for human vision through the faceguard. The faceguard comprises an eye sensor, a head orientation sensor, and an electronic circuit. The eye sensor comprises a video camera and is configured for measuring eyeball movement, pupil size, and/or eyelid movement. The head orientation sensor senses pitch and/or yaw of a person's head.

The present invention relates to a glucose detecting complex and a contact lens-type sensor comprising the same for detecting glucose in tears. The contact lens-type sensor for detecting glucose according to the present invention includes a complex in which glucose oxidase is coupled to cerium oxide nanoparticles. Such a configuration allows the visualization of changes in glucose concentrations and the quantitative measured of glucose in a simpler and more economical way. In addition, glucose concentrations can be monitored in real time through a non-invasive method by measuring the concentration of glucose in tears rather than in blood in comparison with the conventional blood glucose measurement method. Therefore, the present invention can be widely applied in the technical field for the early diagnosis and prevention of diabetes.

Eye health data analysis using artificial intelligence includes receiving, by a mobile device, biometric data from one or more sensors located on a contact lens substrate on a user's eye. The biometric data includes, at least in part, a moisture level of the user's eye. The mobile device identifies a plurality of environmental parameters associated with the user's location using surrounding internet-of-things devices that are communicatively connected with the contact lens substrate and the mobile device. In response to determining that the moisture level in the user's eye is below a predetermined threshold, the mobile device generates a recommendation including automatically adjusting at least one of the plurality of environmental parameters and displays the generated recommendation to the user using an augmented reality system in the contact lens substrate.
