PROBLEM TO BE SOLVED: To make a worker recognize the difference in the kinds of lenses between a spectacle lens for right eye and that for left eye by comprising a display means for recognizably displaying the groups of the spectral lenses on the basis of the result of judgement. SOLUTION: A group to which a finished spectacle lens for right eye belongs and a group to which an unfinished spectacle lens for left eye belongs, are displayed on a liquid crystal display part 3. When the group of the finished lens is different from the group of the unfinished spectacle lens, the monitor mode is transferred to the display of the lens edge simulation image plane. The fact that the group of the finished spectacle lens is plastic lens, is displayed by a graphic symbol with a code RZ1, and the fact that the group of the unfinished lens is a minus lens, is displayed by the graphic symbol with a code RZ2, whereby a worker can recognize that the group of the finished lens is different from that of the unfinished lens.
