An optical plastic product has an optical multilayer film formed on one or both surfaces of a base made of plastic, directly or via an intermediate film, wherein the optical multilayer film includes a tensile-stress high-refractive-index layer having tensile stress as internal stress and made of a high refractive index material, and a low refractive index layer made of a low refractive index material, and the tensile-stress high-refractive-index layer is disposed with a physical film thickness of not greater than 10 nm, in a first layer as counted from the base side in the optical multilayer film.

A pair of ophthalmic lenses adapted for a wearer whose prescriptions for the left and right eye are different by at least 0.25D in cylinder, the rear surfaces of both ophthalmic lenses having a substantially identical shape.

A spectacle lens for at least one eye of a user, a method for producing a spectacle lens, and a computer program product having executable instructions for performing the method for producing the spectacle lens are disclosed. The spectacle lens has a permanent marking which is or contains a diffractive structure, wherein a diffractive pattern generated by illumination of the diffractive structure is configured to be invisible upon a first kind of illumination and configured to be visible only upon a second kind of illumination. The permanent markings on the spectacle lens are, on one hand, invisible to the user or to a spectator looking at the user wearing the spectacle lens without utilizing specially selected optical aids but, on the other hand, enables continued control of the spectacle lens in front of the eye of the user by an optician or a specifically designated optical sensor.

A semi-finished lens includes an object-side surface and an eyeball-side surface and is to be an eyeglass lens completed by processing the eyeball-side surface. The object-side surface of the semi-finished lens includes an optical region and a non-optical region.

An ophthalmic lens system for reducing the risk of progression of a myopic eye by selectively maintaining, inducing or creating asymmetry of the peripheral retinal profile for the eye. A method for reducing the risk of progression of myopia comprising determining the magnitude of asymmetry of the on-axis/off-axis refractive error profile or eye length profile of the eye and providing an ophthalmic lens system that corrects for and provides acceptable on-axis vision and simultaneously controls the position of the off-axis refractive error profile or eye length profile such that resultant profile of the eye is asymmetric.

A method of making an optical article having a gradient tint and a gradient polarization. The method includes providing an optical element including a coating having at least one alignment zone. A dye composition is contacted with the coating. The dye composition includes at least one of: a dichroic dye, a photochromic-dichroic dye, or a combination thereof to diffuse at least a portion of the dye composition into the coating at a predetermined concentration gradient along at least a portion of the coating to provide the gradient tint and the gradient polarization. A kit for making an optical article having a gradient tint and a gradient polarization. An optical article prepared from a method for making an optical article having a gradient tint and a gradient polarization.

A computer implemented method of determining a numerical representation of a spectacle lens is provided, in which a numerically represented working spectacle lens is optimized by ray tracing using pencils of rays along different viewing directions of an eye to obtain an optimized numerical representation. The principal rays of the pencils of rays each pass different ray passing points forming points of a vertex surface. The principal rays extend along a viewing direction related to the respective ray passing point. The locations of the ray passing points are determined by surface points of a non-spherical apex surface representing the locations of the apex of the cornea when the eye rotates. A fixed distance is added to the apex surface at the respective surface points in a direction that corresponds to the viewing direction of the eye when the apex of the cornea is located at that surface point.

The present invention provides an eyeglass lens and its related techniques, the eyeglass lens including: a base region that causes a luminous flux that has entered from an object-side face to exit from an eyeball-side face, and to enter an eye and converge on a retina; and a plurality of defocus regions that are in contact with the base region and that are each configured such that a luminous flux that passes through at least a part of the corresponding defocus region enters the retina as diverging light, in which a defocus spot angle (DSA) of the luminous flux that causes a light spot having a size mainly for cones is set in a defocus region located near the center of the eyeglass lens, and a defocus spot angle (DSA) of the luminous flux that causes a light spot having a size mainly for rods is set in a defocus region located near the periphery of the eyeglass lens.
