ABSTRACT:
An eyeglass lens processing apparatus for processing an eyeglass lens includes: a lens chuck that holds the lens; a regular-grooving tool; a first moving unit that moves the lens held by the lens chuck; a grooving data input unit that inputs 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 basis of the grooving data; a fine-grooving tool; a second moving unit that moves the lens held by the lens chuck; and a selector that selects whether fine-grooving is to be performed. When performance of 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 fine-grooving margin, and controls the second moving unit to perform the fine-grooving on the basis of the grooving data.
