Abstract
A vision screening apparatus includes first and second display units, a processor, and instructions which are executable by the processor. The instructions, when executed by the processor, cause the apparatus to 1) carry out a photorefraction test of a subject, 2) estimate the subject's visual acuity based on the photorefraction test, 3) present the subject with a visual acuity check optotype for an interval of time, and 4) monitor for noncompliance with a visual acuity check protocol during at least part of the time interval.
