PROBLEM TO BE SOLVED: To provide a lens performance inspection device capable of inspecting a performance of a lens to be inspected at a target image height in a short time, without being affected by noises caused by a displacement quantity detecting marker. SOLUTION: The lens performance inspection device 1 is equipped with: a light irradiation section 13 which irradiates an inspection chart 12 with light; a light blocking member 16 which is disposed between the lens to be inspected 11 and the light irradiation section 13, transmits projection light from an inspection pattern P, and blocks projection light from the displacement quantity detecting marker M; and a moving mechanism 17 which moves the light blocking member 16 from a light blocking position where the projection light from the displacement quantity detecting marker M is blocked, to its retraction position relative to the blocking position.
