In certain embodiments, double-vision-related vision defects determinations or modifications may be facilitated. In some embodiments, a stimulus may be to be presented at a first time at a position on a first display for a deviating eye of a user (e.g., without a stimulus being presented on a second display of for a reference eye of the user) to cause the deviating eye to fixate on the position on the first display. A deviation measurement for the deviating eye may be determined based on an amount of movement of the deviating eye occurring upon the presentation on the first display for the deviating eye at the first time. In some embodiments, a modification profile associated with the user may be determined based on the deviation measurement, where the modification profile includes one or more modification parameters to be applied to modify an image for the user.

A retinal imaging system is provided. The system comprises: a fundus camera having a focusing mechanism; an imaging module configured for imaging user's face and eyes and providing image date indicative of a relative orientation between an optical axis of the fundus camera and a line of sight of user's eye at user's eye target position; a position and alignment system configured and operable to utilize the image data indicative of said relative orientation for positioning the fundus camera at an operative position such that the optical axis substantially coincides with the line of sight of user's eye, to enable focusing the fundus camera on the retina; a sensing system comprising one or more sensors, configured and operable for monitoring a user's face position with respect to a predetermined registration position and generating corresponding sensing data; and a safety controller configured and operable to be responsive to the sensing data, and upon identifying that the user's face position with respect to the predetermined registration position

The present disclosure provides systems and methods for diagnosing disease. In some aspects, an imaging system is provided that includes a light source configured to illuminate a retina of the eye with light, one or more imaging devices configured to receive light returned from the retina to generate one or more spatial-spectral images of the retina, and a computing device configured to receive the one or more spatial-spectral images of the retina, evaluate the one or more spatial-spectral images, and identify one or more biomarkers indicative of a neurogenerative pathology.

An ophthalmic apparatus includes an illumination optical system that generates slit-shaped illumination light using a first light source; an optical scanner that deflects the illumination light to a fundus of a subject's eye; an imaging optical system that captures light from the fundus using a rolling shutter method; an acquisition unit that acquires a fundus image of the subject's eye using light from a second light source; a flare determination unit that determines whether or not flare occurs by analyzing the fundus image; a controller that performs flare optimization control by controlling at least one of the first light source, the illumination optical system, the optical scanner, the imaging optical system, and the image sensor based on a first determination result obtained by the flare determination unit; and an image forming unit that forms an image of the fundus when the flare does not occur.

A self service refraction instrument includes an adjustable optical assembly coupled within an instrument housing between an eyepiece and a viewing target display. A defocus correcting component includes a pair of adjustably spaced apart spherical lens elements. An astigmatism correcting component includes a pair of cylindrical lens elements that are synchronously rotatable in opposite directions for adjusting cylinder power and in a same direction for adjusting axis angle. A decision module informed by visual acuity scores for an autorefraction Rx or an old prescription Rx of a test subject, the test subject's communicated choices among presented options of corrective optics prescriptions and a refraction rules database that decides to next test sphere, axis or cylinder, at a specific step size of increments, or to test visual acuity, or to end a test.
