PROBLEM TO BE SOLVED: To measure excellently and accurately optical characteristics of a concave surface height of a spectacle lens, an optical center, a geometrical center, an eye point position, a measurement position of a degree of a remote use, the degree or the like. SOLUTION: At a block position A1, a plurality of the places which is deviated from a center of a convex surface of a lens to be tested S2 is held with an adsorption. The plurality of the places of the convex surface of the lens to be tested S2 which is held with the adsorption by a lens hold transfer device 170 is transferred to a mark detection position B3. At this position, the mark displayed on the convex surface of the lens to be tested S1 is photographed. The position of the mark is calculated by an image processing of this photographed image. Next, the eye point position or the like is calculated from this mark information. Then, the lens to be tested S1 is transferred over a height measurement position B3, the height of the concave surface is measured by the height measurement. Moreover, it is transferred to a degree measurement position B4, the concave surface height of the lens to be tested S2 is adjusted so as to make a degree measurement part become a standard height of the measurement. And the degree is measured by a degree measurement device. COPYRIGHT: (C)2005,JPO&NCIPI
