摘要： Disclosed is a method for automatically centering an ophthalmic lens, including steps of: —positioning the ophthalmic lens on a holder; —acquiring at least one image of the ophthalmic lens received on the holder by means of a camera; and —processing the image to find the position of an optical center of the ophthalmic lens by means of a processing unit. According to the invention, the ophthalmic lens including several distinct centering markings distributed along a geometrical figure, the step of processing includes: —determining, for at least three of the centering markings, the position of at least one characterization point of each centering mark; and —deducing therefrom the position of the optical center of the ophthalmic lens.

摘要： A process, phoropter, and an optometry system, the process being for correction of the shift of the optical power of an active lens in a phoropter due to a temperature change over time, the active lens including a container filled with a liquid and having a deformable curvature membrane under the action of an actuator controlled by an optical power control command, the shift being that the active lens provides an actual optical power that is different from the expected optical power corresponding to the optical power control command. A temperature sensor is arranged in and/or on the phoropter to measure the temperature in the phoropter.

摘要： Embodiments of the disclosure relate to the use of dyes that impart localized regions of reduced transmittance across specific wavelength ranges. The inclusion of transmittance-attenuating dyes into a lens provides enhanced color contrast by tuning the spectrum of visible light transmission through the lens.

摘要： The invention relates to a method for characterizing a visual system of a subject using measures of the sensitivity to contrast, the visual system comprising visual signal processing elements each having an impact on the sensitivity to contrast, wherein a visual test where visual patterns having different spatiotemporal frequencies and with varying luminance levels and with varying levels of visual degradation of the visual patterns are shown to a subject to measure the sensitivity to contrast of said subject, is performed, wherein a predetermined response model of a visual system is preestablished on the basis of a determination of the visual signal processing element that predominantly limits the sensitivity to contrast for each value of luminance and spatiotemporal frequency, said predetermined response model relating the visual signal processing elements predominantly limiting the sensitivity to contrast to the luminances and to the spatiotemporal frequencies, wherein at least one of the visual signal processing elements is selected in order to be investigated, wherein at least one visual test is performed on the visual system of the subject, said visual test being optimized according to said at least one selected visual signal processing element, during the optimized visual test, the variations of the luminance levels and of spatiotemporal frequencies being limited within a range of luminance and a range of spatiotemporal frequency where the predetermined response model locates the visual signal processing element as predominant in limiting the sensitivity to contrast.
