US Patent 10531795 Vision defect determination via a dynamic eye-characteristic-based fixation point

In certain embodiments, vision defect information may be generated via a dynamic eye-characteristic-based fixation point. In some embodiments, a first stimulus may be displayed at a first location on a user interface based on a fixation point for a visual test presentation. The fixation point for the visual test presentation may be adjusted during the visual test presentation based on eye characteristic information related to a user. As an example, the eye characteristic information may indicate a characteristic of an eye of the user that occurred during the visual test presentation. A second stimulus may be displayed during the visual test presentation at a second interface location on the user interface based on the adjusted fixation point for the visual test presentation. Vision defect information associated with the user may be generated based on feedback information indicating feedback related to the first stimulus and feedback related to the second stimulus.
