A vision screening device for administering vision screening tests, and in particular a color vision screening test, to a patient is described herein. The vision screening device may include associated methods and systems configured to perform the operations of the vision screening tests. The device may include a first radiation source configured to generate color stimuli, a second radiation source separate from the first radiation source configured to emit near-infrared radiation, and a sensor configured to capture the near-infrared radiation emitted by the second radiation source, and reflected by an eye of a patient. The device may also be configured to cause color stimulus to be displayed to the patient, and determine measurement(s) of the eye of the patient in response to the color stimulus. The device may be further configured to analyze the measurements to generate a recommendation and/or diagnosis associated with the vision of the patient. The device may also be configured to display the recommendation and/or the measurements, along with additional screening data, to an operator conducting the vision test.

An eye-tracking device includes an optical device that includes a light source with an optical cavity and a light sensor. The light source is positioned to output coherent light toward an eye of a user and receive at least a portion of the coherent light back from the eye of the user as feedback light. The feedback light enters the optical cavity and causes modulation of an intensity of the coherent light. The light sensor is optically coupled with the light source for detecting the modulated intensity of the coherent light and generating one or more signals based on the detected intensity of the coherent light. The eye-tracking device also includes one or more processors that are coupled to the optical device for determining, from the one or more signals, movement information of the eye. A method of detecting movement of an eye using the eye-tracking device is also disclosed.

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 updating a protocol for a Virtual Reality (VR) medical test via a user device having a processor, the VR medical test being performed on a subject via a VR device worn by the subject, wherein the method is performed by the processor and the method comprises: displaying GUI elements associated with the protocol on the user device, the GUI elements having user adjustable settings for modifying a functioning of the VR medical test; receiving a selection input from the user device corresponding to a selection of the GUI elements; receiving a setting input from the user device that corresponds to the selected GUI elements; modifying the user adjustable setting for each of the selected GUI elements according to the corresponding setting input; and updating the protocol based on the user adjustable setting for each of the selected GUI elements and operations associated with the VR device.

A visual field testing apparatus may comprise a display; a line of sight detection unit that detects a line of sight of a user; a visual recognition determination unit that carries out determination as to whether or not the user has visually recognized the target; a target display unit that causes a gazing target and a measurement target to be sequentially displayed at the display; and a visual field testing unit that carries out visual field testing by causing visual recognition determination to be carried out with respect to the measurement target by the visual recognition determination unit as the gazing target and the measurement target are sequentially displayed by the target display unit. The visual field testing unit may have a central scotoma possessor testing mode in which the gazing target is displayed at the display 13 for the eye opposite the eye being tested.

Embodiments of the invention are directed towards systems, methods and computer program products for providing improved eye tests. Such tests improve upon current eye tests, such as visual field tests, by incorporating virtual reality, software mediated guidance to the patient or practitioner such that more accurate results of the eye tests are obtained. Furthermore, through the use of one or more trained machine learning or predictive analytic systems, multiple signals obtained from sensors of a testing apparatus are evaluated to ensure that the eye test results are less error-prone and provide a more consistent evaluation of a user's vision status. As it will be appreciated, such error reduction and user guidance systems represent technological improvements in eye tests and utilize non-routine and non-conventional approaches to the improvement and reliability of eye tests.

A portable ocular screening device for tracking macular degeneration having a portable body including a graduated focusing mechanism including an inner chamber. The apparatus also includes a monocular eyepiece disposed on the graduated focusing mechanism and a display screen and a processor disposed within the inner chamber. Additionally, a method of monitoring macular degeneration includes providing a monocular screening device having a display screen disposed within a body of the screening device. The method further includes displaying an image and also providing a prompt in response to the display of the image. Subsequently, the method includes receiving a response via an input device, the response indicative of a user's perception of the image and evaluating the response to determine if the response indicates a user accurately perceived the first image.

System for integrally measuring clinical parameters of the visual function including a display unit (20) for representing a scene with a 3D object having variable characteristics such as virtual position and virtual volume of the 3D object within the scene; movement sensors (60) for detecting the user head position and distance from the display unit (20); tracking sensors (10) for detecting the user pupils position and pupillary distance; an interface (30) for the user interaction on the scene; processing means (42,44) for analysing the user response based on the data coming from sensors (60,10) and the interface (30), with the characteristics variations of the 3D object; and based on the estimation of a plurality of clinical parameters of the visual function related to binocularity, accommodation, ocular motility and visual perception.

The invention relates to an examination device (1), a method for an automated examination of at least one eye (4, 4′) of a person, a computer program product and the various uses of the examination device (1).

Systems and methods for vision test and uses thereof are disclosed. A method may be implemented on a mobile device having at least a processor, a camera and a display screen. The method may include capturing at least one image of a user using the camera of the mobile device; interactively guiding the user to a predetermined distance from the display screen of the mobile device based on the at least one image; presenting material on the display screen upon a determination that the user is at the predetermined distance from the display screen; and receiving input from the user in response to the material presented on the display screen. The material presented on the display screen may be for assessing at least one characteristic of the user's vision. Mobile devices and non-transitory machine-readable mediums having machine-executable instructions embodied thereon for assessing a user's vision also are disclosed.
