发明名称 CONTACT LENSES HAVING SMOOTHLY JOINED OPTICAL SURFACES.
摘要 <p>Apparatus, products, and methods are described that relate to blending various disparate optical surfaces in a smooth and continuous manner. In cross section, the two disparate surfaces are represented as meridional profiles. A blend zone profile is described by a single third-order polynomial. In the case of rotationally symmetric optics, one cross-section suffices for the description of the entire surface. In the case of non-rotationally symmetric optics, an increased number of cross-sections are necessary to produce the desired three-dimensional surface, thus meridional profiles are calculated at selected azimuthal locations to describe the full surface.</p>
