1. A system configured for one or more of assessment or training of one or more vision disorders of a user, the system configured for data communication with a display apparatus, the system comprising:
one or more processor apparatus; and one or more computer-readable storage media having a plurality of computer-executable instructions stored thereon, the plurality of computer-executable instructions configured to, when executed by the one or more processor apparatus, cause the system to perform a plurality of steps comprising:
identifying a specified exercise for display on the display apparatus, the specified exercise being one of a plurality of exercises configured for one or more of assessment or training of at least one of vergence ability or accommodation ability of the user;
identifying data related to one or more lenses for use in combination with the display apparatus;
based at least on the data related to the one or more lenses, calculating one or more correction factors for image display on the display apparatus, wherein the calculating the one or more correction factors for image display on the display apparatus comprises calculating, for an eccentric visual stimulus of the series of visual stimuli, a scaling factor, the scaling factor comprising one of a magnification factor based on a minification power of a minus lens or a minification factor based on a magnification power of a plus lens;
causing display, on the display apparatus and based at least on the specified exercise and the one or more correction factors, a series of visual stimuli to at least one eye of the user, each visual stimulus of the series of visual stimuli configured to have a specified vergence demand and a specified accommodation demand;
tracking one or more of a vergence response or an accommodation response of the user;
comparing the one or more of the vergence response or the accommodation response to one or more standardized values for vergence response or accommodation response; and
determining, based at least on the comparing, a result indicative of whether the one or more of the vergence response or the accommodation response is associated with visual disorder.
