An eyeglass lens processing system includes: a plurality of processing devices including first and second processing devices, each of the first and second processing devices including a lens processing unit configured to process an eyeglass lens and a processing control unit configured to control the lens processing unit; a memory unit configured to store first processing information based on which the first processing device performs a first process on the eyeglass lens; and a processing setting unit that includes a setting unit configured to set, for each of the first and second processing devices, correction data based on which the first processing information is to be corrected to acquire second processing information. One of the first and second processing devices performs a second process on the eyeglass lens based on the second processing information.
