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,
wherein one of the first and second processing devices performs a second grind on the eyeglass lens based on the second processing information.

2. The eyeglass lens processing system according to claim 1 , wherein
the first processing information is used for processing a non-processed eyeglass lens,
the second processing information is used for processing the eyeglass lens which has been ground based on the first processing information;
the one of the first and second processing devices performs the second grind on the eyeglass lens, which has been ground based on the first processing information based on the first processing information, based on the second processing information.

3. The eyeglass lens processing system according to claim 2 , wherein
the first and second processing devices are configured to sequentially grind a right eyeglass lens and a left eyeglass lens for an eyeglass frame based on the first processing information,
