A lens meter is provided which includes a light source portion (20) with a first light source (21) for generating a lens-characteristic measuring light beam (P2) and a second light source (23) for generating a position specifying light beam (P1). A patterning plate (28) with lens-characteristic measuring patterns (28c) and position specifying patterns (28b) is disposed in an optical path (31) of the lens-characteristic measuring light beam (P2) and position specifying light beam (P1) generated by the light source portion (20). The measuring light beam (P2) is projected onto a subject lens (30) set in the optical path (31) so that the images (28c') of the lens-characteristic measuring pattern (28c) are received. The received images (28c') are analyzed, and the lens-characteristic mapping display of the subject lens (30) is performed. In this lens meter, the first and second light sources (21, 23) are separate from each other.
