An eyeglass lens grinding apparatus for grinding a periphery of a lens. Lens rotating shafts holds and rotates the lens. A lens rotating device rotates the lens rotating shafts. The lens rotating device includes a motor and a transmission member that transmits rotational force of the motor to the lens rotating shafts. An abrasive wheel rotating shaft rotates at least one lens grinding abrasive wheel. An abrasive wheel rotating device rotates the abrasive wheel rotating shaft. The abrasive wheel rotating device includes a motor and a transmission member that transmits rotational force of the motor to the abrasive wheel rotating shaft. A moving device relatively moves the lens rotating shafts with respect to the abrasive wheel rotating shaft to thereby vary an axis-to-axis distance between the each of the lens rotating shafts and the abrasive wheel rotating shaft. The moving device includes a moving motor. An axis-to-axis distance detecting device detects an angle of rotation of the moving motor, to thereby obtain the axis-to-axis distance varied by the moving device. A controller controls processing based on a result of detection by the axis-to-axis distance detecting device.
