Embodiment Construction

[0047] like figure 1 The illustrated embodiment of the method for mounting a lens holder onto an uncut lens for an eyeglass lens comprises steps S1 to S8. These steps are basically accompanied by; moving the uncut lens, determining the position of the uncut lens and measuring the position of the uncut lens with the moving table; taking measurements, forming an image and performing image processing with the lens measuring instrument; and, using the lock The device performs a blocking operation. Therefore, first, an apparatus for mounting a lens holder to a spectacle lens constituted by the above-mentioned apparatus and a computer will be described, and then a method for mounting a lens holder to an uncut lens used as a spectacle lens will be described.

[0048] exist figure 2 Among them, the locking device 2, the mobile workbench 3 and the lens measuring instrument 4 are connected with the computer 6 in such a way that information can be exchanged with the computer 6 and nec...

Abstract

The present invention relates to an apparatus for and a process of attaching a lens holder to an uncut lens for a spectacle lens which enables efficient attachment of the lens holder at a position without the processing interference when the lens holder is attached to a progressive multifocal lens or a multifocal lens. The lens holder can be attached to the uncut lens at a position set outside of a range of processing interference. The range of the processing interference is the range where the processing interference takes place, i.e., a range where a portion of the shape of a lens buildup area of the lens holder is outside the shape of the spectacle frame and the uncut lens cannot be processed.

Description

technical field [0001] The invention relates to a method for mounting a lens holder on an uncut lens of an eyeglass lens, said lens holder being a jig which is previously mounted on the uncut lens and which is ground on the edge of the uncut lens The process is used as the rotation center axis of the uncut lens, and the present invention also relates to the apparatus used in the above method. Background technique [0002] Spectacles are formed by machining an uncut lens (usually a so-called round lens having a circular shape) into a shape matching the shape of a frame and fitting the cut lens into the frame. In order to form glasses, a design is necessary. Determined by using prescription data on the eyes of the person to wear the glasses (diopter, cylindrical power, distance between the right and left eyes, and other similar data) and data on the shape of the frame chosen by the person to wear the glasses The location of the optical center is achieved by these steps. Sai...
