Abstract:
A method for processing a spectacle lens, comprising:measuring a lens and processing the lens, wherein the measuring step comprises collecting optical information including calculating a calculated position of an optical reference point by using a lens meter for measuring optical properties of the lens, the optical properties including a prism value, and the processing step comprises using the optical information collected in the measuring step as a portion of data for effecting lens processing, wherein the measuring step further comprises: measuring the optical properties, including the prism value, of the lens to generate measured data by measuring the optical properties at a point selected on the lens, wherein the selected point is a point of measurement; calculating a calculated optical reference point position, including a calculated position of an optical center, on the lens using the measured data generated by measuring; marking the lens by placing a mark on the lens at the point of measurement or at a point located at a position relative to the point of measurement, and generating mark data representing the position of the mark; processing the mark data representing the position of the mark to determine a relative relationship between the position of the mark and the calculated position of the optical reference point, thereby generating first data representing the relationship between the position of the mark and the calculated position of the optical reference point; and saving the first data to a memory medium, or recording the first data to a recording medium, or transmitting the first data to a lens processing apparatus, so that the first data is subsequently available for effecting the lens processing.
