Latest Patents

Isenberg holds a patent for a Progressive Addition Power Ophthalmic Lens. This lens features base and add spherical regions designed to provide refractive power correction. It includes a central corridor characterized by a power curve expressed as a polynomial of at least the 11th degree. The surface contour of the intermediate corridor is defined by an ordered sequence of osculating spheres. Additionally, the curvature of the surface spreads away from the principal meridian according to a spreading function with substantially circular level curves. Visual astigmatism is effectively corrected over a significant portion of the base and add spheres through the superposition of an aspheric function to the sag of the lens surface.
