Abstract
A vision screening device displays visual stimuli and captures image(s) of the eye while the visual stimuli is changing over a period of time. The vision screening device uses the images to determine and monitor refractive error, ambient light level(s), pupil size, and gaze angle as the visual stimuli changes over the time period. Based on the refractive error, a determination of hyperopia and/or presbyopia is made. Based on the gaze angle and/or the pupil size, a confidence metric is determined. Based on the confidence metric and/or the determination, a recommendation for the patient is generated and displayed.
