摘要：A lens meter having a measuring optical system comprises a device for measuring an optical characteristics continuously, a device for introducing the lens to the desired positional relation for a measuring optical axis in the measuring optical system on the basis of the measured data, a device for generating the alignment ending signal when the alignment is achieved to the predetermined standard level, a device for judging whether the measured data is stable within a predetermined permissible range of the variation, and a device for storing the measured data of the lens based on the judgment result. This apparatus further comprises a device for designating which the left or right lens should be measured, a device for generating the signal for reading-and-storing the measured data, a device for storing the measurement result, a device for detecting whether the lens exists on the measuring optical axis, and a device for judging the changing-over of the left or right of the lens. This apparatus further comprises a device for changing-over a mode to measure an additive diopter in the progressive multi focus lens, a device for inputting which the lens is for left or right, a device for detecting a displacement of a measuring position, a device for conducting to a right and left reference axis of the lens, a device for conducting a measuring position closed to the near viewing section from the far viewing section, and a device for displacing the measuring position closed to the near viewing section to the predetermined nose position. <IMAGE>
