Claim:
An eyeglass lens processing apparatus for processing an eyeglass lens, the apparatus comprising: a lens chuck that holds the lens; a regular-grooving tool; a first moving unit that relatively moves the lens held by the lens chuck with respect to the regular-grooving tool; a grooving data input unit that inputs grooving data, the grooving data including a width and depth of the groove to be formed in the lens; a controller that controls the first moving unit to perform regular-grooving on the lens on the basis of the input grooving data; a fine-grooving tool; a second moving unit that relatively moves the lens held by the lens chuck with respect to the fine-grooving tool; and a selector that selects whether or not fine-grooving is to be performed, wherein when performance of the fine-grooving is selected, the controller performs the regular-grooving on the lens so that a bottom and side surfaces of the groove have a margin for the fine-grooving, and controls the second moving unit to perform the fine-grooving on the lens on the basis of the input grooving data.
