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.

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 screening platform enables comprehensive ocular evaluations. The screening platform includes a harness that is configured to fit a head of a patient and that includes one or more electronic components that are operable to power an interchangeable module, a central processing unit (CPU) with a graphical processing unit (GPU), and the interchangeable module with communication capabilities to external computational devices, multiple display output devices, and several types of input devices from both an operator and a patient at-hand, wherein the interchangeable module is separable from the screening platform.

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.

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.

Embodiments of the present invention analyze readable text in digital content displayed in a user interface for color deficiencies based on a user profile and determine a first color deficiency is present based on the user profile associated with a user viewing the readable text in the digital content. Embodiments of the present invention identify a first color substitution for the first color deficiency based on the user profile, where the user profile includes a color palette with a plurality of variations of a plurality of recognizable colors by the user and the first color substitution is from the plurality of variations of recognizable colors by the user. Embodiments of the present invention display the first color substitution for the first color deficiency as an overlay on the digital content, where the overlay covers at least the first color deficiency.

A vision testing device includes a light-occluding casing for administering vision tests. A viewing station is coupled to the light-occluding casing so a test subject can see a first digital display housed within the light-occluding casing. A second digital display is external to the light-occluding casing and is configured to receive touch-based input. One or more predetermined vision tests are displayed via the first digital display. The second digital display receives input corresponding to the vision test displayed via the first digital display. The second digital display includes response indicators that can be activated via a swiping motion on the second digital display, and a response is recorded as a result of the swiping motion. Each answer corresponding to a swiping motion is stored and output as a result of the vision test.

Systems and methods for determining whether to enable color blind accessibility settings within the course of a user interactive narrative are described herein. Virtual color blindness indication objects containing colors that are visibly distinguishable within a single dichromatic visual spectrum can be utilized in objectives to determine a user's dichromatic visual deficiency type.

Provided is a visual target display device or a visual target presentation method which can test the cone-specific visual function more accurately in a device that displays a visual target, of a chromatic color, for testing the color-related visual function of a subject or a method of presenting the visual target. A visual target of a chromatic color and a background around the visual target are presented in such a way that the brightness of the background is a numerical value between a numerical value 10% less than the brightness of the visual target and a numerical value 10% greater than the brightness of the visual target and a combination of the color of the visual target and the color of the background is a combination of colors which are in a relationship of confusion colors in dichromatism.
