摘要: An ophthalmic technician is present with a patient in an exam room to operate eye examination equipment and transmit patient information to remote location. At that remote location, a skilled technician is present to provide the necessary optical care, and may operate the phoropter from the remote location. Using video and/or teleconferencing equipment and a phoropter located in the patient examination room along with management software, the system works to determine the final optical prescription for the patient. That information, coupled with findings from other devices which are integrated with the management software, and that the patient uses locally, are reviewed by a remote-based optometrist or ophthalmologist.

摘要: Eye prescriptions may be determined by providing a simple, easy to use, portable device with a specially configured targeting light source that aligns the eye, mitigates accommodation, and provides accurate results. Unlike stationary, closed view autorefractors, this device typically is portable, self-usable, relatively inexpensive, enabling more widespread use across the world.

摘要: A device is for screening a person for CI and may include a binocular viewer, a display adjacent the binocular viewer, and a processor and associated memory cooperating with the display. The processor may be configured to display on the display a first visual stimulus and a second visual stimulus, cause, in alternating fashion, convergent movement and divergent movement in the first visual stimulus and the second visual stimulus along a visual stimulus path, determine respective centroid positions of the second eye and the first eye during the convergent and divergent movement of the first visual stimulus and the second visual stimulus, and calculate an IPD, and compare the IPD with the visual stimulus path to obtain a dynamic IPD, the dynamic IPD serving as an indicator for whether the person has CI.

摘要: In exemplary implementations of this invention, a bi-ocular apparatus presents visual stimuli to one eye of a human subject in order to relax that eye, while measuring refractive aberration of the subject's other eye. Alternately, a monocular device presents stimuli to relax an eye while testing the same eye. The apparatus induces eye relaxation by displaying virtual objects at varying apparent distances from the subject. For example, the apparatus may do so by (i) changing distance between a backlit film and a lens; (ii) using extra lenses; (iii) using an adaptive lens that changes power; (v) selecting distinct positions in a progressive or multi-focal length lens; (vi) selecting distinct optical depths by fiber optical illumination; (vii) displaying a 3D virtual image at any given apparent depth; or (viii) display both a warped version of the real world and a test image at the same time.

摘要: Systems for determining an individual's current focal distance by measuring parameters associated with binocular vision focusing using one or two contact lenses are provided. In an aspect, a system includes a first contact lens and a second contact lens respectively configured to be worn over first and second eyes of an individual. The first contact lens and the second contact lens respectively include first and second circuits configured to respectively generate first data related to the first eye and second data related to the second eye for determining the current focal distance.

摘要: Methods, devices, and systems are disclosed for determining refractive corrections of human eyes to reduce and eliminate image distortion associated with eyeglasses. In some embodiments, an objective refraction module is configured to measure refractive errors of an eye objectively, without subjective feedback from a tested subject. A computation module is configured to generate a plurality of objective prescriptions. A phoropter module is configured to perform a subjective refraction for determining a plurality of subjective spherical powers based on the plurality of objective prescriptions. An output module is configured to generate a plurality of prescriptions for eyeglasses, the plurality of prescriptions comprising (a) a first prescription having a first subjective spherical power fs1, a first objective cylinder power Fc1, and a first objective cylinder angle Fa1, and (b) a second prescription having a second subjective spherical power fs2, a second objective cylinder power Fc2, and a second objective cylinder angle Fa2.

摘要: This document discloses both a method for visual field examination that makes it possible to perform eye sensitivity examinations and an instrument that is configured to perform said method for visual field examination. The method is based on absolute conditions, i.e. absolute differences in the differential luminous thresholds between symmetrical points with respect to the vertical meridian or the horizontal meridian are used; in this way, unlike with already-known methods, it is possible to study the symmetry and/or the harmony of the subjects themselves, without having to compare them to a reference population with all that this entails.

摘要: A system and method for using a virtual reality or an augmented reality environment for the measurement and/or improvement of human vestibulo-ocular performance can be implemented by combining a video camera based eye orientation sensor, a head orientation sensor, a display, and an electronic circuit that connects the eye sensor, head sensor, and display. The system and method can be operated in the range of frequencies between 0.01 Hertz and 15 Hertz. The system and method can use a Fourier transform to compute a gain and a phase. The system and method can be used for measuring vestibulo-ocular reflex, dynamic visual acuity, dynamic visual stability, kinetic visual acuity, retinal image stability, or foveal fixation stability in a non-clinical setting. The system and method can be completely portable, head-worn, and self-contained.
