Provided is a technique by which it is possible to reduce the thickness of a polarized lens for spectacles that has a rotationally symmetric aspherical surface formed on an object-side surface thereof, in the same manner as for a normal lens. Provided is a polarized lens for spectacles, including: a first lens substrate having an object-side surface on which a convex surface that is a rotationally symmetric aspherical surface is formed; a second lens substrate having an eyeball-side surface; and a polarized film disposed between the first lens substrate and the second lens substrate and having a convex shape toward the object-side surface, wherein an in-plane distribution of a distance W between the object-side surface and the polarized film has concentricity.

A method of manufacturing a button-enabled housing assembly includes pre-forming a composite button component or insert having an elastically flexible button membrane that is mounted on a rigid frame, and thereafter molding a housing over the button insert. The composite button insert is formed in a co-molding operation and can include a rigid island in the flexible button membrane for supporting a cosmetic keycap.

To ease and improve the production of objects, a method is described for producing an object (60) comprising a structural core (10) and an outer coating of polymeric material (52), comprising the steps of (i) coating with polymeric material (50) a lamina (10), wherein the lamina comprises a surface exhibiting macroscopic discontinuities (32) configured so that the polymeric material grips to them in order to form a multilayered piece; (ii) removing parts from the multilayer piece to obtain a contour corresponding to the object, the contour comprising an edge (B) along which a margin of the lamina remains uncovered by the polymeric material.

A hand held tool (10, 60, 70) for use by an optician in bending the temples (120) of a pair of eyeglasses includes an elongated handle portion (12, 62, 72) capable of being held in the palm of the optician's hand. A mandrel including a convexly formed anvil (14, 64, 74) with a nonslip upper surface (67, 77a) extends from a first end of the handle portion. A concavely formed thumb recess (16, 66, 76) is located adjacent the first end of the handle portion and is located opposite the anvil (14, 64, 74). The optician's thumb (100) fits within the recess when the handle portion is being held. The free end (110) of an eyeglass temple is placed over the mandrel (14, 64, 74) and is bent over the mandrel by the optician.

Systems and methods are disclosed for generating an eyewear frame and lens geometry that is customized to a user's anatomy and optimized for optical performance. One method includes receiving a configurable parametric model of a user-specific eyewear product comprising a frame portion and a lens portion, wherein geometric parameters of the configurable parametric model are based geometric features of a user's anatomy; receiving media data of a user, the media data including the user's response to visual cues; detecting the position of the user's eyes from the received media data; determining optical information of the user based on the detected position of the user's eyes; and generating an updated configurable parametric model by modifying the received configurable parametric model based on the determined optical information.
