摘要： A method to determine a binocular alignment includes measuring a disassociated phoria of a patient at a first simulated distance by presenting fusible images including targets with a first parallax corresponding to the first simulated distance, using a headset stereo display at a screen distance; presenting non-fusible images by presenting the target for a first eye with the first parallax and presenting a disassociated targetless image for a second eye, and measuring the disassociated phoria in response to the presenting of non-fusible images, using an eye tracker of the headset; and determining a vergence of the patient at the first simulated distance by presenting fusible images for the first and second eyes with the first parallax, corrected with the measured disassociated phoria; measuring an associated phoria in response to the presenting of fusible images; and determining the vergence as a combination of the disassociated phoria and the associated phoria.

摘要： A system to determine a binocular alignment, comprises a first optical unit, including a first display, to display images for a first eye, actuatable along a longitudinal direction according to a simulated distance and an optical power of the first eye, and a first eye tracker assembly, to track a gaze direction of the first eye, adjustable in a horizontal lateral direction to accommodate a pupillary distance of the first eye; and a second optical unit, including a second display, to display images for a second eye, actuatable along the longitudinal direction according to a simulated distance and an optical power of the second eye, and a second eye tracker assembly, to track a gaze direction of the second eye, adjustable in the horizontal lateral direction to accommodate a pupillary distance of the second eye; and a computer, to determine the binocular alignment based on the gaze directions.
