Abstract:
1. A method for describing a shape of a lens, the method comprising at a computational device: receiving lens profile data of a lens, fitting to the lens profile data a mathematical function comprising mathematically linear combinations of polynomials, wherein a surface profile of one half of the lens, divided along an optical axis, is described by said mathematical function, outputting a mathematical lens profile description based on the fitting of said mathematical function, wherein outputting a mathematical lens profile description comprises outputting a description of said surface profile of one half of the lens and another half of the lens, symmetric about the optical axis to said surface profile of one half of the lens, said surface profiles intersecting at the optical axis, further comprises computing and outputting at least one of a surface area and a volume of a lens described by the intersecting surface profiles.
