PROBLEM TO BE SOLVED: To carry out high accuracy measurement of the three-dimensional surface shape of the inner surfaces of orthokeratology contact lenses. SOLUTION: For measuring the three-dimensional surface shape of the inner surface 2s of a contact lens 2, such as an orthokeratology contact lens, having a shape having both a plurality of combined regions having different curves and at least blended parts of combined parts; and a button type lens 1, having a machined surface machined into a shape having a plurality of regions and non-blended combined parts of the region is used as a holder of the contact lens 2 to be measured. While the boundary of the region of the button-type lens 1 is verified via the contact lens 2, in a state of being held on the machined surface 1s of the button type lens 1, the three-dimensional surface shape of the contact lens is measured.
