摘要： A method and a device are described for determining the optical center point of the lenses of spectacles to be manufactured for a spectacle wearer, whose head is imaged from the front using a digital camera (10), wherein the location of the pupils (16) and the interpupillary distance (20, 21) are determined with the aid of an image evaluation program to define the optical center point of the lenses. To provide advantageous conditions, it is proposed that the face of the spectacle wearer is imaged having a measurement frame (1) held on the head via a nose rest (4) and earpieces (3) and having a view oriented on a fixation point (13) fixedly associated with the camera (10), a front region of the measurement frame (1) has two lateral marking points (7) and a middle marking point (8) placed frontally in front of these lateral marking points (7), the angles of the viewing lines (15) in relation to the image plane are determined with the aid of the image evaluation program from the mutual distances and locations, which are measured in the facial image, of the pixels of the three marking points (7, 8) and the pupils (16), before the measurement points (19), which are corrected with respect to parallel viewing lines (17), are ascertained to determine the interpupillary distances (20, 21) in relation to the nose rest (4).

摘要： A method of fabricating a lens element for an adjustable power lens of the kind comprising two lens elements that are slidable relative to one other in a direction transverse the optical axis of the lens and have respective lens surfaces that are shaped to act together to form a corrective lens, the power of which varies according to the relative disposition of the two lens elements, the method comprising the steps of forming a lens puck having two opposite faces, which are shaped to form opposite lens surfaces of one of the lens elements of the adjustable power lens, the puck having at least one alignment feature, and thereafter edging the puck to a desired eye shape with reference to the alignment feature.

摘要： 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.

摘要： An eyewear device has a lens retention mechanism that establishes electrical contact between onboard electronics and a lens ring by a resiliently compressible electrical contact member, such as a spring washer, located within a housing defined by a body of the eyewear device. The retention mechanism can further include a lock screw that is selectively engageable with the lens ring to allow disposal between retention and release of a lens by the lens ring, the lock ring being captured in the housing such as to resist removal of the lock screw from the housing when the lens ring is released for lens removal.

摘要： On a first aspect, the spectacle lens is selected as including a transparent support in which is coded an identifier readable by an external reading tool for retrieving the identifier. A distant server is contacted using the identifier and data related to the spectacle lens is so gathered. On a second aspect, data related to the spectacle lens is provided to a predetermined database. Upon receiving a request issued from a requester, the database is accessed and at least some of the data is retrieved, the request including at least part of the identifier, and the retrieved data is sent to the requester.
