    Abstract: An optometric testing device comprising a first shutter and a second shutter placed in front of two eyes of a patient and configured to present an activated state in which a shutter blocks the propagation of light and a deactivated state in which the shutter allows the propagation of light, a communication unit configured to communicate with a display system in order to send and/or receive a synchronization signal, and a control unit configured to command each shutter as a function of the synchronization signal so that the first shutter and the second shutter change state with a first frequency and a second frequency, wherein the control unit is configured to command each shutter so that the first frequency is different from the second frequency and/or so that a duty cycle of activation of the first shutter is different from a duty cycle of activation of the second shutter.

    Abstract: Embodiments of the invention include a method to determine a binocular alignment, the method comprising: measuring a disassociated phoria of a first eye and a second eye of a patient at an apparent distance; and determining an accommodative convergence of the first eye and the second eye at the apparent distance using the measured disassociated phoria. In other embodiments, a system to determine a binocular alignment comprises a stereo display, for a projection of images for a first eye and a second eye; an accommodation optics, to modify the projection of the images according to an apparent distance; an eye tracker, to track an orientation of the first eye and the second eye; and a computer, coupled to the stereo display, the accommodation optics and the eye tracker, to manage a determination of the binocular alignment.

    Abstract: The present disclosure provides a scene camera system including a scene camera that includes a lens and may detect light reflected off an exterior of an eye into the lens and send a signal corresponding to the detected light to a processor. The system further includes a main camera that may detect light reflected off an interior structure of the eye and send a signal corresponding to the detected light to the processor. The system also includes an image processing system including the processor that executes instructions to produce a scene camera digital image of the eye and a main camera digital image of the eye. The system further includes a multiple picture-in-picture display that displays the scene camera digital image of the eye and the main camera digital image of the eye concurrently.

    Abstract: The exemplified systems and methods disclosed herein involve the contemporaneous and concurrent stimulation of both eyes of a patient with dissimilar visual scenes that substantially span an expected or normal visual field of both eyes. During an assessment via the exemplified system and methods, a test eye (i.e., eye being assessed) is presented a visual scene that is rich in contours (e.g., a scene with rich texture patterns) that substantially span an expected or normal visual field of a person while the non-tested eye is presented an impoverished visual scene (e.g., a contour-free or non-distinguishing-contour scene, e.g., with a homogeneous color, with respect to the contour-rich scene). Defects in the visual field can be detected by assessing for breaks or discontinuity in the observation of the contour-rich scene by the person.
