Patent ID: 11793403

Abstract:
Methods and systems for assessing and/or treating visual disorders, such as discorder in accommodative ability and/or vergence ability, of a person are provided. Assessment and training exercises can be performed utilizing a computerized system in communication with a head-mountable display (HMD), such as a virtual or augmented reality display, which can display visual targets at various vergence and accommodative demands. Lenses, such as inverted bifocal lenses, may be used in combination with the HMD to mimic natural accommodative demand during viewing or to enable assessment and treatment of accommodation disorders. Corrective factors can be calculated and utilized for generation of visual targets to account for lens characteristics and/or interpupillary distance mismatch. Accommodation and vergence responses can be tracked during display of the visual targets at the various demands, and assessed in comparison to normalized values for assessment of vision disorders or utilized to track progress of user in treatment of a vision disorder.
