Abstract: In some examples, a controller of a wearable device causes display by the wearable device of a test image, and adjusts a color property of the displayed test image. In response to an input provided by a user responsive to the displayed test image as the color property is adjusted, the controller determines a distribution of color wavelengths for an eye of the user, and detects a color vision deficiency of the user based on the determined distribution of color wavelengths. The controller provides control information to control a display device of the wearable device to compensate for the color vision deficiency.
