摘要：
A lens shape measuring apparatus is provided which comprises lens rotating shafts (16, 17) for rotatably holding an uncut lens, a feeler (63, 219, 220) disposed in contact with a working locus of the front or rear surface of the lens, and a calculation/control circuit (100) for detecting a difference in surface level of the lens from a change in data measured by the feeler (63, 219, 220) and controlling the contact of the feeler with the lens.
