PROBLEM TO BE SOLVED: To enable a more suitable setting of the height of a rear V-block of a spectacle lens.SOLUTION: A V-block forming data setter that sets V-block forming data for making a spectacle lens processing device having a rear V-block processing tool that forms a rear V-block on the rear face side of a spectacle lens circumference form a V-block in the spectacle lens circumference includes: first V-block height acquisition means that acquires the first V-block height of the rear V-block every radius vector angle of a spectacle lens; and second V-block height setting means that sets the second V-block height that is a local modification of the height of the rear V-block with respect to the first V-block height acquired by the first V-block height acquisition means and sets a modification range of radius vector angles and the second V-block height of the modification range.SELECTED DRAWING: Figure 8 |
