Abstract
A lensmeter capable of measuring near-infrared ray transmittance of an eyeglass lens by adding a near-infrared ray measurement function to the lensmeter. The lensmeter includes a near-infrared ray transmittance measuring unit that includes a light emitting unit including a near-infrared ray light source for irradiating a measured lens with a near-infrared ray; and a light receiving unit including a near-infrared ray sensor for measuring a near-infrared ray transmittance of the measured lens by detecting an intensity of the near-infrared ray passing through the measured lens, and is located at one end of a housing of the lensmeter.
