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.

The present invention relates to a test system for assessing color vision variability of test persons (7). The test system comprises at least two test carriers (1), wherein each of the at least two test carriers (1) is provided with a two-dimensional pattern (4) including a background (2) and a plurality of samples (3). The plurality of samples (3) and the background (2) of each one of the at least two test carriers (1) are made of at least two different dyestuff combinations representing metameric colors. The samples (3) and/or the background (2) show color scaling in at least two directions such that each one of the at least two test carriers (1) is configured to provide that a test person (7) can select a spot (PIS.sub.C) from the two-dimensional pattern (4) where the metameric colors of the samples (3) and the background (2) match best. The system further comprises a test illuminant unit (5) configured to provide light for the color vision variability assessment, the light having a specific spectral power distribution. The system further comprises a processing unit (6) configured to predict a color matching function and/or to determine a congenital and/or acquired color vision deficiency of the test person (7) by calculating a variation of the spot (PIS.sub.C) selected by the test person (7) as compared to a spot (PISS) computed by the processing unit (6) based on data of a predefined standard observer considering the specific spectral power distribution of the light of the test illuminant unit (5).

Embodiments of the present disclosure relate to computer storage, methods, and systems for the optimization of accessible color themes. Systems and methods are disclosed that leverage the use of confusion lines to identify and highlight relationships between colors that may be inaccessible (e.g., indistinguishable) for a person with a vision impairment, such as a color vision deficiency. In some embodiments, a graphical user interface is provided that, based on a selection of colors in a color wheel, visually indicates curves of confusion for each color in the selection of colors. Each curve of confusion visually indicates a confusion of colors for a type of vision impairment, such as a CVD.

A system for ocular assistance is disclosed. The plurality of subsystem includes an ocular condition registration subsystem, configured to register one or more users. The plurality of subsystem includes an ocular calibration subsystem, configured to determine a plurality of ocular settings. The plurality of subsystem includes a device configuration identification subsystem, configured to determine a plurality of device settings for each of one or more device associated with the registered one or more users. The plurality of subsystem includes a screen customization subsystem, configured to determine values corresponding to the plurality of ocular settings based on a pre-stored look up table and determined plurality of device settings. The screen customization subsystem modifies current values corresponding to the plurality of ocular settings to the determined values. The system modifies or rectifies the screen images or texts for suffering users.
