Cup attaching apparatus

A cup attaching apparatus for attaching a cup for eyeglass lens processing to a subject lens to be processed, comprising:

• an imaging optical system, which obtains an image of the lens by illuminating the lens with rays of light shaped to be larger in diameter than the lens;
• a display;
• a display control unit, which displays, on the display, the obtained lens image and an alignment mark of a progressive multifocal lens, superimposed on the obtained lens image;
• a first input unit, which inputs an amount of offset of a far-use eyepoint with respect to a hidden mark of the progressive multifocal lens;
• and
• a second input unit, which inputs layout data for layout of the lens with respect to a target lens shape,
• wherein the display control unit determines a display position of the alignment mark based on the inputted offset amount and layout data, and displays the alignment mark at the determined display position on the display.
