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.

Disclosed is a binocular optoelectronic device wearable by a user for measuring a light sensitivity threshold of the user, including: a diffuser configured to face eyes of the user; at least one light source for emitting light toward the diffuser. The diffuser includes predetermined parameters allowing to provide a quasi-homogeneous light diffusion to at least one eye of the user from light emitted by the at least one light source.

In some embodiments, initial feedback indicating threshold characteristics (under which a user sees initial stimuli presented on a user interface) may be provided to a prediction model, and a set of predicted characteristics (for a set of locations of the user interface) and a set of confidence scores associated with the set of locations may be obtained via the prediction model. Based on the set of confidence scores, one or more locations may be selected to be tested during a visual test presentation. As an example, the locations may be selected over one or more other locations of the set of locations based on the set of confidence scores. Based on predicted characteristics associated with the selected locations, stimuli may be presented at the selected locations during the visual test presentation. Visual defect information for the user may be generated based on feedback from the visual test presentation.
