A method for manufacturing a spectacle lens includes the steps of providing an integral main lens. The integral main lens has a front surface and a back surface and is at least one selected from a group consisting of a spherical power lens, an astigmatic power lens, and a lens having a main curvature of the front surface in a first meridian and a main curvature of the back surface in the first meridian which are different so as to provide for a spherical power different from zero; and applying at least one additional lens element to at least a part of the front surface and/or at least a part of the back surface, wherein the at least one additional lens element includes at least one layer having a multitude of layer elements, in particular printed layer elements. Further, the invention is directed to a corresponding spectacle lens.

An apparatus is for ascertaining and outputting a type of spectacle lens suitable for a spectacle wearer with a visual characteristics providing device, for providing visual characteristics of the spectacle wearer, a needs providing device, for providing individual needs of the spectacle wearer, a spectacle lens type providing device, for providing a plurality of types of spectacle lenses having predetermined characteristics, a desired characteristics ascertaining device, for ascertaining desired characteristics of a type of spectacle lens using the provided visual characteristics and the provided individual needs of the spectacle wearer, an assigning device, for assigning at least one type of spectacle lens from among the plurality of types of spectacle lenses to the desired characteristics, on the basis of predetermined assignment rules, and a spectacle lens type outputting device, for outputting the at least one assigned type of spectacle lens. A method is for ascertaining and outputting a type of spectacle lens suitable for a spectacle wearer and also a computer program is for carrying out the method.

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 &ldquo;substantially balanced reflectance&rdquo; 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.

The present invention relates to novel ophthalmic lens elements and eyewear having wide field of view, low distortion, improved astigmatism correction where required and enhanced eye protection properties. Series of lens elements have steeply curved spherical reference surfaces. The edged lenses of the series have approximately consistent aperture size, shape and hollow depth across a range of common prescriptions. Novel sunglasses, laser protective eyewear, and lens edgings, coatings and frames are included in the invention.
