Abstract:
1. A method for determining a bevel curve in a high power minus lens, comprising the steps of: inputting a value of a curve of a convex face of the high power minus lens; and calculating a value of the bevel curve based on the inputted value of the curve of the convex face of the high power minus lens, wherein the value of the bevel curve is calculated as follows, when the value of the curve of the convex face is 2.0 or smaller, then when the value of the curve of the convex face is 2.0˜4.0. then when the value of the curve of the convex face is 4.0˜7.0. then when the value of the curve of the convex face is 7.0 or greater, then wherein K
