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.

Method of making wide field spherical lenses and protective eyewear

Optical lens element with a prescription zone, suitable for use in wraparound or protective type eyewear. The element may also include a peripheral vision zone, with no prismatic jump between the zones. Design methods for the prescription zone include temporally rotating a prescription section about a vertical axis through the optical center thereof, and/or decentring the optical axis of said prescription section relative to the geometric axis thereof, and providing partial surface correction for astigmatic and/or mean power errors. For prescription powers in the range &#x2212;6.0 to +6.0 diopters with 0 to 3 cyl, the optical lens element may be designed such that its front surface can be mounted in a frame of constant curvature of at least 5.0 diopters, with its back surface providing good clearance from temples and eyelashes. Applications include ophthalmic sunglass lenses.

Single vision lenses

An optical lens element of wrap-around or shield type wherein the aperture of the lens outline or edge of at least one surface of the optical lens element is of generally ovaline shape and located on the surface of a sphere whose radius of curvature corresponds to 11 D or above, a toroid where the horizontal radius or curvature corresponds to 11 D or above, or a surface where the radius of curvature changes across at least one section of the lens aperture.

Lenses and spectacles bearing lenses

Wide field spherical lenses and protective eyewear

The disclosure relates to spectacle frames including frames adapted to engage ovaline edges of lens elements having a toroidal or changing base curvature. In a preferred embodiment the frame shape corresponds to the edge of front surfaces of a pair of lens elements having a high curvature which is common to various prescriptions.

Spectacles frames for shaped lens elements

Shaped ophthalmic lenses

Disclosed are novel molding methods for injection molding thermoplastic lens elements and particularly adapted for the manufacture of steeply curved and/or thin-centered lenses.
