F(y) is a coordinate of a function point of the basal portion of the first area, along the local normal direction using the bottom joining point with the basal portion of the second area as the origin of the coordinates along the local normal direction, the function point having y as coordinate along a local direction perpendicular to the local normal direction;
n is the refractive index of the material of the lens;
k is a constant.
