The invention is based on a sun protection device, in particular sunglasses, with at least one optical sun protection filter comprising at least one liquid-crystal cell, and with at least one sensor unit, which is configured for capturing a solar irradiation. It is proposed that at least one sensor cover, which covers a sensor surface of the at least one sensor unit at least partly and which is, at least partly, at least substantially opaque with respect to an irradiation of a visible light spectrum.

A sheet for manufacturing articles, particularly frames for glasses and the like, including at least one technical layer made of a thermoplastic material interposed between a first aesthetic layer and a second aesthetic layer, both made of a material such as fabric. A method for producing a sheet for manufacturing articles includes the steps of providing at least one technical layer made of a material such as thermoplastic polymers and at least two aesthetic layers made of a material such as fabric and associating the technical layer with the aesthetic layers. The layers are mutually compressed and then heated to obtain the sheet.

Disclosed is eyeglasses equipment (1) including a frame (10), and at least one ophthalmic lens (20) mounted into the frame. The equipment includes a colored interface (30) that is placed between the frame and the lens.

A method produces a spectacle arm that has an arm body (1) made of plastics material and a metal support inlay (3), in which method the arm body (1) is manufactured additively with a receiving recess for the support inlay (3) and then the support inlay (3) is introduced into the receiving recess of the arm body (1). The arm body (1) is manufactured additively with a longitudinal groove (2) as the receiving recess, which extends at least along a portion of the arm body, and the longitudinal groove (2) with the introduced support inlay (3) is injected with plastics material.

A method for manufacturing one-piece corrective eyewear. The method includes a first step wherein an item with essentially flat blank shape is formed by a 3D-printing process. The item encompasses two lens portions, a bridge portion, and two temple portions; or the two lens portions and the bridge portion. The method includes a second step wherein the item is deformed into a wearable shape. During the first step a frame portion surrounding the lens portions is formed as part of the blank shape.

A method of eyewear manufacture including: adhering frame material onto a surface of a corrective lens, the frame material extending along at least 10% of an edge circumference of the lens; and attaching the lens to a second lens.

Process for making a temple for an eyeglass frame, which comprises: a step of arranging an elongated body made of plastic material; a first heating step, in which the elongated body is heated up to its softening temperature; a step of housing the elongated body in a shaped concavity of a mold; a second step of heating a metallic core; a step of inserting the metallic core in the elongated body. In addition, the housing step is preceded by a step of positioning an ornamental element in a seat provided within the shaped concavity of the mold, in which the ornamental element is retained by means of shape coupling,
