摘要： A lens meter is provided which comprises a light source for generation of a measuring light beam and a pattern forming plate provided in an optical path of the measuring light beam. The pattern forming plate has a central pattern for measuring lens characteristics of a narrow area on an eyeglass lens and a plurality of peripheral patterns for measuring lens characteristics of a wide area on the eyeglass lens. The pattern forming plate can be switched between a normal measuring mode which receives the image of the central pattern based on the measuring light beam transmitted through the narrow area of the eyeglass lens and also measures the narrow area alone and displays the measured values and a wide-area measuring mode which receives a great number of images of the peripheral patterns based on the measuring light beam transmitted through the wide area of the eyeglass lens and also measures the wide area and performs mapping display.

摘要： A lens meter is provided in which a measurement light beam emitted from a light source (21) is projected onto a lens (L) to be inspected, an amount in travel of the measurement light beam which has passed through the lens (L) is then detected by a TV camera (34), and the refractive characteristics of the lens (L) based on the detection result are computed by an arithmetic and control circuit (35) and are displayed by a display unit (3). In the lens meter, the arithmetic and control circuit (35) computes cylindrical power of a distance portion (40) of the lens (L) in consideration of cylindrical power and a direction of a cylindrical axis from the detection result of the TV camera (34), and then computes cylindrical power in distortion areas (42, 43) except the distance portion (40), a progressive portion (41), and a near portion (41') in consideration of the cylindrical power and the direction of the cylindrical axis. After that, the arithmetic and control circuit (35) subtracts the cylindrical power of the distance portion (40) from the cylindrical power of the distortion areas (42, 43). Based on the obtained subtraction results, the arithmetic and control circuit (35) computes boundary lines (44, 45) between the distance, progressive, and near portions (40, 41, 41') and the distortion areas (42, 43) except these portions, and allows the display unit (3) to display the boundary lines (44, 45).
