ABSTRACT:
An eyeglass lens processing apparatus includes: a processing tool that processes a periphery of an eyeglass lens; a lens chucking shaft that holds the lens; a rotating unit that rotates the chucking shaft; a first moving unit that relatively moves the chucking shafts with respect to the processing tool; a lens holding arm that is provided with first and second lens holders for holding the lenses; a second moving unit that moves the lens holding arm; and a controller that controls the first and second moving units so that the first lens holder and the chucking shaft are moved to a first transfer position to transfer the lens therebetween, and, following the processing of the lens which is held by the first lens holder, the second lens holder and the chucking shaft are moved to a second transfer position to transfer the lens therebetween.
