Abstract: In some embodiments, a wearable device performs a visual test that includes simultaneously presenting a first eye stimulus for a first eye of a user of the device and a second eye stimulus for a second eye of the user, where the first eye stimulus has a display characteristic level greater than a display characteristic level of the second eye stimulus. The display characteristic level of the first eye stimulus and second eye stimulus are sequentially increased until feedback information indicates detection of at least one of the first eye stimulus or the second eye stimulus by the user. In response to the feedback information indicating such detection by the user, the other stimulus is presented at one or more sequentially increasing display characteristic levels until the feedback information indicates detection of the other stimulus. Ocular anomaly information of the user is generated based on the feedback information.
