An augmented reality AR system and method for a retail experience include a waveguide apparatus that includes a planar waveguide and at least one optical diffraction element The AR retail system and method recognizes user location in a retail establishment, retrieves data corresponding to the retail establishment and generates virtual content relating to the retail establishment based on the retrieved data. The AR retail system and method creates a virtual user interface in a user's field of view. Virtual content is displayed on the virtual user interface while the user is engaged in retail activity and may be based on user input. The AR retail system and method may provide entertainment, facilitate the shopping experience, offer virtual coupons, render games based on locations throughout a store or based on a shopping list, provide information about food choices such as calorie counts, and identify metadata associated with items.

A spatially compact, lightweight positioning system for guiding an operator in positioning an ophthalmic instrument relative to an eye of a test subject has first and second light sources and an area detector spaced apart from a measurement axis of the instrument and from each other for providing positioning images which may be evaluated relative to stored calibration image information to determine current position of the instrument relative to the eye. The first and second light sources may fit within a lateral distance less than or equal to 25 mm. First and second illumination axes associated with the light sources may reside in a horizontal plane containing the measurement axis, and an observation axis of the area detector may reside in a vertical plane containing the measurement axis. The light sources and the area detector may be intersected by a plane which is normal to the measurement axis.

A wearable display device is disclosed and includes a main body, a heat dissipation processing module and an inflatable actuation module. The main body includes a front cover, a lateral cover, an inflatable airbag, a circuit board and a microprocessor. The heat dissipation processing module is configured to perform heat exchange with the microprocessor, and includes a first actuator, a heat pipe and a cooling chip. The inflatable actuation module includes a base, a ventilation channel, a second actuator and a valve component. When the second actuator and the valve component are driven, the valve component is opened and the second actuator is enabled, the gas is transported and inflates the inflatable airbag through the ventilation channel, so that the main body is stably fitted and positioned on the head of the wearer.

Configurations are disclosed for a health system to be used in various healthcare applications, e.g., for patient diagnostics, monitoring, and/or therapy. The health system may comprise a light generation module to transmit light or an image to a user, one or more sensors to detect a physiological parameter of the user's body, including their eyes, and processing circuitry to analyze an input received in response to the presented images to determine one or more health conditions or defects.

A method of, and apparatus for, aligning an ophthalmic instrument relative to an eye is disclosed, and can include aligning an esthesiometer with a patient's eye. Other aspects of the method and apparatus of the present invention are further described herein.

An implantable ocular drain includes a body and a compliant portion. The body includes a first end configured to seat in an anterior chamber of an eye. The first end includes an inlet for ingress of aqueous humor into the implantable ocular drain. The body further includes a second end configured to seat in a tear film of the eye. The second end includes an outlet to release a flow of the aqueous humor into the tear film. The body further defines a tortuosity and a fluid conduit. The body includes a lumen having a lumen length and a lumen cross sectional area. The lumen length and the lumen cross sectional area and the tortuosity are configured to control an intraocular pressure (IOP) of the eye by controlling the flow of the aqueous humor through the lumen. The compliant portion is at the second end.

A system and method for measuring biomechanical properties of tissues without external excitation are capable of measuring and quantifying these parameters of tissues in situ and in vivo. The system and method preferably utilize a phase-sensitive optical coherence tomography (OCT) system for measuring the displacement caused by the intrinsic heartbeat. The method allows noninvasive and nondestructive quantification of tissue mechanical properties. Preferably, the method is used to detect tissue stiffness and to evaluate its stiffness due to intrinsic pulsatile motion from the heartbeat. This noninvasive method can evaluate the biomechanical properties of the tissues in vivo for detecting the onset and progression of degenerative or other diseases and evaluating the efficacy of therapies.

System, devices and methods for monitoring pupillary response(s) are presented; the system comprises a light-blocking enclosure for receiving a first eye and a second eye of an individual, a light source for emitting visible light inside the enclosure and illuminating said first eye and/or second eye according to a predetermined illumination schedule, an image capturing unit for receiving visible light reflected from the first eye and/or the second eye while each eye being illuminated by said light source, and for capturing a plurality of images at a specific rate of the first eye and/or the second eye, a control unit for controlling operation of the light source and the image capturing unit and for receiving first data indicative of the plurality of images, a processing unit for processing the first data to determine second data indicative of size of pupil(s) of the first and/or second eye(s) in each of said plurality of images and processing the second data to enable determining an ophthalmological condition of the individual and generating an output signal indicative thereof, and an output interface for receiving the output signal from the control unit and presenting the output to the individual.
