The accuracy of the axial degree of a lens in an eyeglass production is improved. In an eyeglass frame measuring apparatus, first and second frame data on the eyeglass frame consisting of first and second frames are entered. The entered first frame data are inverted to obtain a third frame data. On the basis of the third frame data and the entered second frame data, an amount of deviation of the second frame data with respect to the third frame data in a rotation direction is obtained. An eyeglass lens is processed on the basis of the rotation deviation amount and the third frame data. <IMAGE> |
