A spectacle lens image sensing processing apparatus comprises a mark detector (53) for detecting a micro engraved mark by sensing an image of a convex surface of a lens (A) to be examined and performing image processing, a lens power measuring device (54); and switching means (55) to switch between mark detection and power measurement. Said mark detector includes a lens holder (37) a first light source (31), a half mirror (34), an image sensing unit (48), and a condenser lens (38), an imaging lens (39), and a reflection screen (40). Said power measuring device including a lens mount base (57), a second light source (58), a light-sending lens (59), a collimator lens (60), and a target (61) interposed between said light-sending lens and said collimator lens to be movable in an optical axis direction, and an objective lens (65) and a transmission screen (66).
