    摘要: A computer-readable medium includes computer-executabie instructions that cause a processing unit of a user device to instruct a user to stand a predetermined distance from the user device, acquire an image of the user, and determine a user interpupiliary distance based on the acquired image. The user interpupiliary distance indicates a distance between the user's pupils in terms of pixels. The executable instructions further cause the processing unit to determine a current distance between the user and the user device based on the user interpupiliary distance, a predetermined interpupiliary distance, a width of the acquired image in terms of pixels, and a field of view of the camera. Additionally, the executable instructions cause the processing unit to display the current distance between the user and the user device on a display and display an eye chart when the determined current distance is equal to the predetermined distance.

    摘要: An imaging system captures a plurality of images of the subject's face at each of a series of successive time periods in which a subject is looking in respective directions. Using the images for each time period, the system forms a respective skin model of a skin portion of the subject's face and obtains eye data characterizing an eye of the subject. The system uses the skin models to convert the eye data for the multiple time periods into a common frame of reference, and then uses the eye data to obtain a numerical eye model in the frame of reference indicative at least of the position of the centre of the eye's rotation (CER). Typically, such an eye model is obtained for each of the subject's eyes. The eye model is used in a process for designing an item of eyewear, or in an augmented-reality or virtual-reality system.

    摘要: The present invention concerns a method for manufacturing an intraocular ophthalmic lens intended for a patient, this method comprising the following steps: • measuring biometric data specific to the patient; • choosing a distribution of light to be obtained after correcting the patient's vision; • choosing a type of aberration to be corrected and an extent of aberration correction to be applied; • determining intrinsic parameters of the lens; • from the results of the biometric data measurements, form the type and extent of aberrations to be corrected, from the selected light distribution and from the determined parameters of the lens, calculating geometrical parameters for the lens in such a way that the set formed by the ophthalmic lens and the eye of the patient generates a light distribution specification corresponding to the chosen light distribution and to the chosen aberration corrections. The invention further concerns an ophthalmic lens obtained by said method.

    摘要: A portable retinal imaging device for imaging the fundus of the eye. The device comprises an ocular imaging device containing ocular lensing and filters, a fixation display, a light source, and is configured for coupling to a mobile device containing a camera, display, and application programming for controlling retinal imaging. The light source is configured for generating a sustained low intensity light (e.g., IR wavelength) during preview, followed by a light flash during image capture. The ocular imaging device works in concert with application programming on the mobile device to control subject gaze through using a fixation target when capturing retinal imaging on the mobile device, which are then stitched together using imaging processing into an image having a larger field of view.
