This disclosure includes methods and systems for producing ophthalmic lenses. Some methods include identifying a plurality of zones within a spatial representation of a lens blank, selecting, for each of the zones, one or more parameters for producing the lens, and producing the lens by removing material from the lens blank according to the one or more parameters of each of the zones.

Implementations of a system for the manufacture of eyeglasses is disclosed. The system includes a lens-mounting block, a lens blank coupled to the lens-mounting block, a lens coupled to the lens blank, and an edger. The edger follows a perimeter of the lens-mounting block to edge a perimeter of the lens. The lens blank detaches from the lens-mounting block after the lens is edged.

Disclosed is an apparatus and method for processing eyeglass lens which determines the completion of the eyeglass lens processing by using a hall sensor. The eyeglass lens processing apparatus comprises: a grinding wheel mounted frame (22) mounted with a grinding wheel (20) for grinding a lens, and whose position is changed according to a predetermined grinding depth of the lens; a carriage (12) for moving the lens to contact with the grinding wheel (20), and which contacts with the grinding wheel mounted frame (22) when the lens which contacts with the grinding wheel (20) is grinded to the predetermined grinding depth; and a hall sensor detector (30) for detecting a contact of the grinding wheel mounted frame (22) and the carriage (12), wherein the hall sensor detector (30) includes a magnet (32) and a hall sensor (34) for detecting an intensity of a magnetic field generated by the magnet (32), the magnet (32) is equipped on either one of the carriage (12) and the grinding wheel mounted frame (22), and the hall sensor (34) is equipped on the other one of the carriage (12) and the grinding wheel mounted frame (22), in case an output signal of the hall sensor (34) is A when the grinding wheel mounted frame (22) and the carriage (12) are in contacts with each other, if the output signal of the hall sensor (34) is smaller or larger than A by a tolerance, it is determined that the grinding wheel mounted frame (22) and the carriage (12) are in a separated state.

The disclosure discloses a grinding method using a grinding device, and a grinding device. The disclosure provides a grinding method using a grinding device, where the method includes: moving a grinding wheel toward a sample stage, and recording a position of the grinding wheel when the bottom of a grinding groove comes into contact with a piece to be ground as a standard position; moving the grinding wheel toward a position detector, and recording a position of the grinding wheel when a position of the bottom of the grinding groove coincides with a detecting center of the position detector as a first reference position; moving the grinding wheel back to the standard position, and grinding the piece to be ground, according to a preset grinding amount using the grinding wheel; and adjusting the position of the grinding wheel.

Disclosed is a method for generating settings for machining an optical lens, including: a) acquiring a file characterizing the shape to which the optical lens must be machined in order to allow it to be mounted in a spectacle frame; b) decomposing the shape into a plurality of distinct objects, including an exterior envelope inside of which all the other objects are located; c) determining a machining order of the other objects; and d) generating the machining settings depending on the machining order.

An eyeglass frame shape measurement device measures a shape of an eyeglass frame. The eyeglass frame shape measurement device includes a light projecting optical system that has a light source and emits measurement light from the light source toward a groove of a rim of an eyeglass frame, a light receiving optical system that has a detector and causes the detector to receive reflected light of the measurement light emitted toward the groove in the rim of the eyeglass frame by the light projecting optical system and reflected by the groove of the rim of the eyeglass frame, an acquisition section that acquires a cross-sectional shape of the groove of the rim of the eyeglass frame on the basis of the reflected light received by the detector, and a luminance control section that controls a luminance level of the reflected light to be received by the detector.
