The present invention relates to an apparatus and a method for processing eyeglass lenses. According to an embodiment of the present invention, the apparatus and the method for processing eyeglass lenses are capable of measuring the displacement in a thickness direction from at least three points on the surface of the lens along the random radial direction of the eyeglass lens; measuring the displacement in a thickness direction from multiple points on the surface of the lens along the circumferential direction of the eyeglass lens; calculating the displacement in a thickness direction with respect to multiple points corresponding to the shape of an eyeglass frame by using the measured displacement in a thickness direction; and processing the eyeglass lens based on the same. Coordinates of the central point on the surface of the lens are calculated by using a relative value with at least three points based on the displacement in a thickness direction measured from at least three points in the random radial direction, and the radius of curvature is calculated with respect to multiple circumferential angles by using the displacement in a thickness direction from the measured multiple points along the circumferential direction and the calculated coordinates of the central point on the surface of the lens. Moreover, the displacement in a thickness direction with respect to a point on the surface of the lens of the corresponding circumferential angle can be calculated based on the coordinates of the central point on the surface of the lens, and the radius of curvature based on multiple circumferential angles. Therefore, the position of the surface of the lens to be processed can be simply and quickly measured. |
