摘要： A pair of progressive ophthalmic lenses (1, 2) meets special conditions for improving binocular vision of a wearer, while avoiding discomfort for peripheral vision. A first one of the conditions relates to height values of far vision fields, intermediate vision fields and/or proximate vision fields, for indicating that the fields are different enough in height between both lenses. A second one of the conditions sets a maximum value for the relative difference in mean refractive power gradient between both lenses.

摘要： Providing to an eye a customizable ophthalmic lens comprising a transparent set of electroactive cells (24) juxtaposed to a lens surface for providing an optical phase-shift distribution function. The method includes providing (402) a reference phase-shift distribution function adapted to provide a given dioptric function DF(α, β); determining (404) the actual gaze direction (αa, βa); choosing (406) a reference gaze direction (αR, βR); calculating (408) an actual point Pa at the intersection between the actual gaze direction and the transparent set of electroactive cells, and a reference point PR at the intersection between the reference gaze direction and the transparent set of electroactive cells; calculating (410) a modified phase-shift distribution function by shifting the reference phase-shift distribution function according to a vector {right arrow over (PRPa)}; and activating (412) the electroactive cells according to the modified phase-shift distribution function.

摘要： The present invention relates to a group of novel electrochromic materials. More specifically, it relates to electrochromic materials based on either single or two-core viologen systems and the use of these viologen systems as a variable transmittance medium for the manufacture of an optical article, such as an ophthalmic lens.

摘要： Systems and methods for providing identification factors for an individual wearer. Some or all of the identification factors when within a predetermined value provide a prescription and corrective ophthalmic lenses for a selected individual wearer, the corrective ophthalmic lens having at least one correction that is to the nearest 0.20 diopter, or is in a range between about the nearest 0.01 diopter and about the nearest 0.20 diopter. The prescription and corrective ophthalmic lenses are obtained by at least first analysis performed with a first instrument, a second analysis performed with a second instrument, and a third analysis performed with a third instrument, in which each instrument is different, and each analysis is different.

摘要： The invention relates to an ophthalmic lens comprising: a substrate having a given refractive index; and a coating that minimizes ultraviolet reflections, said coating having a given refractive index and being deposited on a rear face of the substrate. According to the invention, the thickness of the ultraviolet-reflection-minimizing coating is between I μm and approximately 200 μm and the refractive index of the ultraviolet-reflection-minimizing coating is at least 0.15 units less than the refractive index of the substrate. The invention also relates to a method for the production of such a lens.

摘要： A method includes: providing lens blank data relating to the first, second and peripheral blank surfaces of the lens blank; providing optical lens data relating to the first, second and peripheral optical surfaces of the optical lens; virtually positioning the optical lens in the lens blank in a position so that at least one of the first optical surface or the second optical surface is included within the lens blank; evaluating a manufacturing prism cost function, the machining prism cost function corresponding to a weighed sum of the first manufacturing prism to be used when blocking the lens blank on the second surface to machine the first optical surface and of the second manufacturing prism to be used when blocking the lens blank on the first optical surface to machine the second optical surface. The positioning and evaluation steps are repeated so as to minimize the manufacturing prism cost function.
