A patient monitor capable of measuring microcirculation at a tissue site includes a light source, a beam splitter, a photodetector and a patient monitor. Light emitted from the light source is split into a reference arm and a sample arm. The light in the sample arm is directed at a tissue site, such as an eyelid. The reflected light from the tissue site is interfered with the light from the reference arm. The photodetector measures the interference of the light from both the sample arm and the reference arm. The patient monitor uses the measurements from the photodetector to calculate the oxygen saturation at the tissue site and monitor the microcirculation at the tissue site.

Biometric systems capture and combine biometric information from more than one modality, employing digital processing algorithms to process and evaluate captured images having data for a biometric characteristic. Such digital algorithms may include a pupil segmentation algorithm for determining a pupil image in the captured image, an iris segmentation algorithm for determining an iris image in the captured image, an eyelid/eyelash segmentation algorithm for determining an eyelid/eyelash image in the captured image, and an algorithm for measuring the focus on the iris. Some embodiments employ an auto-capture process which employs such algorithms, in part, to evaluate captured images and obtain the best possible images for biometric identification.

A system and method are provided for measuring the thickness of a tear film layer and the heights of tear menisci around upper and lower eyelids of an eye. A plurality of images are acquired between consecutive blinks the eye using optical coherence tomography (OCT). The images depict the tear film layer and tear menisci as distinct from the cornea of the eye. In an embodiment, a plurality of reflectivity profiles from an OCT image are aligned and averaged. The difference between a first peak and a second peak of the average reflectivity profile is measured to determine the thickness of the tear film layer. The heights of the upper meniscus and the lower meniscus can also be measured from the same OCT image. In an embodiment, thickness measurements from the plurality of OCT images are combined. The measurements can be used to diagnose tear disorders, analyze treatments of dry eye and evaluate artificial tears.

In some embodiments, the shield includes active components such as energy diversion devices, heating, cooling, monitoring, and/or sensing. In some embodiments, the shield is configured to protect an eye, mouth, nose or ear while allowing the ultrasound to treat the surrounding tissue. One embodiment of an eye shield is configured to fit under at least one eyelid and over a portion of the eye.

A therapeutic eye and eyelid cover provides heated saturated air to the covered tissue and a transparent front (18, 19) to enable clear vision during use. The cover includes heating means (17) and means (22) for saturating the air enclosed against the face with water vapor, preventing evaporation from the eye and eye lids and enhancing heat transfer to the covered tissue. The transparent front is constructed to prevent condensation and maintain clear vision at all times during use.

A mobile phone which is an example of electronic equipment includes an infrared camera and an infrared LED. The infrared camera is arranged above a display and the infrared LED is arranged below the display. A user, by an eye-controlled input, designates a button image or a predetermined region on a screen. When a line of sight is to be detected, an infrared ray (infrared light) emitted from the infrared LED arranged below the display is irradiated to a lower portion of a pupil. Accordingly, even in a state that the user slightly closes his/her eyelid, the pupil and a reflected light of the infrared light can be imaged.

The present invention is directed to novel compositions and methods effective for maintaining eyelid hygiene, e.g., therapeutic treatment and prophylaxis. The present invention provides methods and compositions that are compliance-enhancing and useful for daily prophylaxis, which involve the easy and safe application of a foam directly to the eyelid in controlled doses effective for maintenance of eyelid hygiene.

Apparatus for monitoring movement of a person's eye, e.g., to monitor drowsiness. The system includes a frame that is worn on a person's head, an array of emitters on the frame for directing light towards the person's eye, and an array of sensors on the frame for detecting light from the array of emitters. The sensors detect light that is reflected off of respective portions of the eye or its eyelid, thereby producing output signals indicating when the respective portions of the eye is covered by the eyelid. The emitters project a reference frame towards the eye, and a camera on the frame monitors movement of the eye relative to the reference frame. This movement may be correlated with the signals from the array of sensors and/or with signals from other sensors on the frame to monitor the person's level of drowsiness.

The present invention is related to a method for designing and making a contact lens which comprises stiffening rib features that provide even distribution of pressure from the lens over the cornea of an eye and/or allows the lens structure to maintain balance of forces for consistent and correct lens orientation on an eye during lens translation or eye lid movement. The invention also provides a soft contact lens comprising stiffening rib features that provides localized directional reinforcements to the lens structure to evenly distribute pressure from the lens over the cornea of an eye and/or to maintain balance of forces for consistent and correct lens orientation on an eye during lens translation or eye lid movement.

The OculoKinetic Device is used to test an individual to evaluate brain functions and to identify the presence of a traumatic brain injury or disease which manifests itself through abnormal ocular responses to stimuli by using the high-speed tracking of an individual's eye movements, pupil size and reactivity, eye lid position and blink parameters and optionally along with other ocular elements, i.e., eyeball pressure, temperature, blood flow, etc. The eye movement stimulus protocol uses a target that moves in any direction of the two-dimensional plane and may use a color display or geometric shapes. In addition, the stimuli can be used in conjunction with cognitive testing, balance assessment, and other non-eye tests.
