a controller configured to change one of the first and second processing tool units to be used for processing the eyeglass lens to the other of the first and second processing tool units by controlling driving of the shaft angle changing portion to change the shaft angle of the lens chuck shaft;
wherein the controller performs a predetermined processing process by controlling the shaft angle changing portion to adjust the shaft angle of the axis of the lens chuck shaft with respect to the first processing tool unit and the second processing tool unit when processing the eyeglass lens;
the eyeglass lens processing apparatus further comprising a driver configured to linearly move both the first processing tool unit and the second processing tool unit along the reference axis relative to the shaft angle changing portion,wherein the at least two spindles of at least one of the first and the second processing tool units includes at least three spindles which are linearly arranged such that a common vertical axis intersects each of the at least three spindles.
