Production information such as an edging mark 31 indicating a region of a lens remaining after edging and reference position marks 32 are depicted in a region, to be cut off by the edging, of a surface of a lens 10 for spectacles. Any production information does not remain on the finished lens 10 after the edging. A lens processing system 100 includes a reference position detecting apparatus (120 and 130) for detecting a reference position of a spectacle lens, and a marking apparatus (170, 160, 150 and 110) for depicting production information of the lens on a specific surface of the spectacle lens on the basis of the reference position information obtained by the reference position detecting apparatus (120 and 130).
