Method for determining optimum thickness of ophthalmic lens |
摘要 |
A method for determining the optimum thickness of an ophthalmic lens comprises the steps of applying data indicative of the kind of a lens suitable for a spectacle wearer and the contents of a prescription as inputs to a computer, executing necessary computation by the computer according to a predetermined program on the basis of the various input data thereby drawing a map of an equi-thickness line group of the ophthalmic lens on the basis of the result of computation, and placing a spectacle frame at a predetermined position on the map of the equi-thickness line group to find out the outermost equi-thickness line within the extent of the frame.
