  • Patent number: 6768581
    Abstract: A coated optical lens includes a lens element and a coating on the surface of the lens element. The coating exhibits a substantially balanced reflectance from the center to a radius proximate the edge of the lens element. The term “substantially balanced reflectance” means that where the thickness of the coating varies across the surface of the lens, the lightness, hue and chroma of the reflectance vary in a balanced manner such that variations in visual appearance are either imperceptible or generally acceptable to an observer. For example, variations in chromatic attributes, such as hue, from the center to the edge of the lens may be balanced by a reduction in lightness from the center to the edge. Preferably, the lens element includes a surface of high curvature upon which the balanced reflectance coating is deposited.
