    摘要: The present disclosure relates generally to a system and method for determining the pupillary distance of a person, more particularly determining the person's pupillary distance by using a computerized screen. The system and method do not require the trip or expense of a doctor or store visit, and are optimized for convenience and cost effectiveness. In a general embodiment, the present disclosure provides a method for determining a pupillary distance of a person without physically measuring the pupillary distance with a device. The method includes receiving a front facial image of the person, determining a scale of the image based on an estimated canthal distance, and determining the pupillary distance of the person based, in part, on the determined scale of the image.

    摘要: Method for determining, in a natural posture, at least one geometric/physiognomic parameter associated with the mounting of an ophthalmic lens in a spectacle frame intended to be worn by a wearer. The method includes: (a) capturing at least one substantially frontal image of the wearer's head; (b) determining a measured value of an angle of inclination during the capturing step, which depends on the inclination of the wearer's head about a main axis perpendicular to a sagittal plane of the wearer's head; (c) determining a reference value of the angle of inclination corresponding to a natural posture of the wearer's head; and (d) determining the required geometric/physiognomic parameter on the basis of the substantially frontal image captured and as a function of the difference between the measured value of the angle of inclination determined in step (b) and the reference value of the angle of inclination determined in step (c).

    摘要: The invention relates to a method of determining an ophthalmic lens for a wearer's eye, the method comprising the following steps: measurement, on the wearer in binocular vision, of the three-dimensional coordinates of the centre of rotation (COR) of the wearer's eye; measurement (10) of at least one viewing direction in a natural posture; determination of the desired position of the ophthalmic lens; calculation of the characteristics of the ophthalmic lens using the measured coordinates and the determined position and the measured direction in the natural posture. Measuring the position of the centre of rotation of the eye in binocular vision ensures that the lens obtained is best adapted for the wearer.

    摘要: An apparatus for and methods of determining that the placement and alignment of progressive add lenses (PALs) in a subject's frame are correct. Namely, a PAL verification tool includes a chart and light source, wherein the chart is viewed by the subject and the light source is worn by the subject during a PAL verification process. The PAL verification method may include the steps of positioning the subject with respect to a near fixation point, the subject viewing the near fixation point with one eye and bringing it into best and clearest vision, measuring and recording a first head position with respect to the near fixation point, the subject viewing the near fixation point with the other eye and bringing it into best and clearest vision, measuring and logging a second head position with respect to the near fixation point, and determining the amount and direction of the difference in the first and second head positions and correlating to an amount and direction of PAL misalignment. A measured misalignment exceeding certain tolerances indicates that a subject's PALs aren't properly positioned in their frame. A subject is suitable for correction if this misalignment causes the subject to experience visual or physical discomfort.
