A lens shape measuring apparatus for measuring a peripheral shape of a spectacle lens, comprising: a lens holding mechanism section for holding the spectacle lens with a holding axis from the side of a lens surface; a first laser displacement meter for measuring a lens peripheral shape by irradiating a laser beam to a periphery of the spectacle lens and receiving a reflected light thereof; and a second laser displacement meter for measuring the lens peripheral shape by irradiating a laser beam to the periphery of spectacle lens and receiving a reflected light thereof, wherein the first laser displacement meter and the second laser displacement meter have a light projecting section for projecting the laser beam and a light receiving section for receiving the reflected light thereof, the light projecting section and the light receiving section in the first laser displacement meter are aligned in a direction perpendicular to an axis line of the holding axis, the light projecting section and the light receiving section in the second laser displacement meter are aligned in a plane containing the axis line of the holding axis or are in a plane in parallel with the axis line of the holding axis, the lens holding mechanism section is adapted to change a lens holding position without changing an axial direction of the holding axis, the first laser displacement meter is adapted to irradiate the laser beam to the periphery of the spectacle lens at each lens holding position, and to measure the lens peripheral shape, and the second laser displacement meter is adapted to measure the lens peripheral shape at the same measurement position as the first laser displacement meter to complement a measured value acquired by the first laser displacement meter. a lens holding mechanism section for holding the spectacle lens with a holding axis from the side of a lens surface; a first laser displacement meter for measuring a lens peripheral shape by irradiating a laser beam to a periphery of the spectacle lens and receiving a reflected light thereof; and a second laser displacement meter for measuring the lens peripheral shape by irradiating a laser beam to the periphery of spectacle lens and receiving a reflected light thereof, wherein the first laser displacement meter and the second laser displacement meter have a light projecting section for projecting the laser beam and a light receiving section for receiving the reflected light thereof, the light projecting section and the light receiving section in the first laser displacement meter are aligned in a direction perpendicular to an axis line of the holding axis, the light projecting section and the light receiving section in the second laser displacement meter are aligned in a plane containing the axis line of the holding axis or are in a plane in parallel with the axis line of the holding axis, the lens holding mechanism section is adapted to change a lens holding position without changing an axial direction of the holding axis, the first laser displacement meter is adapted to irradiate the laser beam to the periphery of the spectacle lens at each lens holding position, and to measure the lens peripheral shape, and the second laser displacement meter is adapted to measure the lens peripheral shape at the same measurement position as the first laser displacement meter to complement a measured value acquired by the first laser displacement meter.
