    摘要： A system for determining a personalized value of an optical feature of a corrective ophthalmic lens which is intended to be worn in front of an eye of an individual for correcting his vision, the system including: a trial optical corrective device adapted to be place in front of an eye of an individual, the trial optical corrective device providing a correction to an individual complying with an initial value of an optical feature; an eyewear adapted to be placed in front of the trial optical corrective device worn by the individual and adapted to immerse the individual in a virtual environment, the eyewear being designed to present, in the virtual environment, a visual task to the individual adapted to determine an adjustment value; a processing unit programmed calculate a personalized value of the optical feature based at least on the initial value and the adjustment value.

    摘要： An ophthalmic spectacle lens having transmittance properties that block UV and violet light and partially block certain cyan wavelengths to enhance contrast between blue versus green and partially block certain yellow wavelengths to enhance contrast between green versus red, and keep in accordance with the tristimulus values. Adding wavelength-selective organic dyes provides the entire functional attributes of the current invention or improves the contrast-enhancing attributes provided by a glass wafer having functional rare-earth oxides, either of which improve multi-band spectrum that is balanced in blocking UV light, and adding contrast between the primary colors to optimize color-enhancing functions. When using organic dyes for all functional attributes it is possible to integrate these dyes into plastic ophthalmic materials. Some lenses are polarized. Unlike other color-enhancing sunglass lenses, this invention may help protect the eyes from over-exposure to some high-energy visible blue light, which may lead to age-related macular degeneration (AMD).

    摘要： A toric lens includes a first surface, a second surface, two first sector zones, and two second sector zones. The first surface and the second surface are opposite to each other. Each of the first sector zones has a first curvature on the first surface along a radial direction of the toric lens, and the first curvature is constant along an arc direction of the toric lens. The two second sector zones are alternately arranged with the two first sector zones. Each of the second sector zones has a second curvature on the first surface along the radial direction, and the second curvature is constant along the arc direction. The first curvature is steeper than the second curvature.
