Abstract

A spectacle lens supply method for a system which includes a terminal installed at a lens orderer side and at least a computing device installed at a lens processor side and connected to the terminal via a communication line, for supplying spectacle lenses. In the lens supply method, the terminal transmits processing condition data including at least one of lens information, frame information, prescription values, layout information and processing information to the computing device, and the computing device calculates a desired lens shape including a bevel figure based on the received processing condition data, creates accept/reject information as to whether a lens process including beveling is possible or not, based on the result of the calculation, and transmits the accept/reject information to the terminal, which information is displayed at the terminal to permit the lens orderer to learn whether the lens process including beveling is possible or not.
