A molding device includes mold shells and a gasket for manufacturing by molding an ophthalmic lens configured to be worn by a wearer, the mold shells each having a molding face and a peripheral side and the gasket including a closed loop portion sandwiched between the molding faces and remotely to the peripheral sides, thus forming a molding cavity of the ophthalmic lens inside the closed loop portion of the gasket, the gasket including a plurality of elongated positioning members each projecting externally from the closed loop portion and each being fastened on a said peripheral side of at least one of the mold shells, the elongated positioning members each having a respective length which is determined in function of an optical axis characteristic of the wearer.

There are provided a lens, a method of fabricating the lens, and a light scanning unit. The lens includes a lens portion having an effective optical surface, and a gate-side flange portion between the lens portion and a gate-side end of the lens. If the lens is disposed between two polarizers configured to polarize light linearly in perpendicular directions and is illuminated in an optical axis direction, interference fringes are generated on the lens, and peripheral interference fringes of the interference fringes extend continuously from the gate-side end and are longer than the gate-side flange portion.

The present invention provides methods for forming an ophthalmic lens that can include a media insert and/or electronic components. In particular, the present disclosure provides for adhesion promoting functionalization steps for a biocompatible coating to bind a hydrogel material to a plastic surface or electronic component prior to the polymerization of the hydrogel. In some aspects, the media insert can be used to contain energy sources and/or functional electronic components which may be, for example, in a stacked integrated component configuration to permit a generally arcuate shape that can conform to the anterior surface of an eye.

A method for producing an optical element includes providing a first partial body which is transparent for the predetermined wavelength range and including on its upper side a structured section, applying a coating which is optically effective for the predetermined wavelength range onto the structured section in order to form the optically effective structure, and applying a cover layer which is transparent for the predetermined wavelength range onto the upper side of the first partial body by means of casting of thermoplastic material and/or duroplastic material.

Disclosed herein is an injection molding method for making optical thermoplastic lenses using 3D—printed functional wafers. The method employs a variable injection molding cavity temperature that is heated to at least wafer Tg—10° C.

A method for manufacturing an optical article, such as an ophthalmic lens, with both photochromic and ultraviolet protecting properties, and to an optical article with said properties.

A method for dyeing a transparent article made of a polymeric substrate with gradient tint comprising: a) a first step of photodegrading the polymeric substrate (1) of the transparent article, by irradiation (3) of at least one first surface of the article to UV radiations to produce a gradiently photodegraded surface layer of the polymeric substrate, and b) a second step of dyeing said first face of the article with a dyeing agent so as to diffuse said dyeing agent into the gradiently photodegraded surface layer of the polymeric substrate.

Ophthalmic lenses are described herein. An example ophthalmic lens may comprise a first surface. The example ophthalmic lens may comprise a second surface disposed opposite the first surface and defining a volume of lens material therebetween. The ophthalmic lens may exhibit a first cylinder power. A difference of the volume of lens material of the ophthalmic lens and a volume of lens material of a comparative lens may be minimized. The comparative lens may consist essentially of the same lens material as the ophthalmic lens and exhibit a second cylinder power different from the first cylinder power.

Disclosed herein is a process to modify a pair of eyeglasses having a first color to produce a pair of modified eyeglasses having at least the portion of the frame comprising a second color. A kit to modify a pair of eyeglasses is also disclosed.

A protective film-attached functional sheet includes a protective film bonded to a functional sheet including aromatic polycarbonate sheets and a functional layer sandwiched between the aromatic polycarbonate sheets, the functional layer being a polyvinyl alcohol polarizing film layer, a photochromic layer, or a combination. The protective film is a polyolefin resin film that includes at least two layers: a base layer formed of a polypropylene having a melting point equal to or higher than a glass transition temperature of the aromatic polycarbonate and an adhesive layer on one surface of the base layer and being a resin composition containing a polyolefin rubber and a polyolefin having a melting point lower than the glass transition temperature but equal to or higher than 15° C. lower than the glass transition temperature; or at least three layers: the aforementioned two layers and an intermediate layer between the base layer and the adhesive layer.
