Benefits of technology
The patent describes a lens that has been designed to improve optical performance in frames and goggles. The lens has separate projecting portions that are positioned during formation and can be pre-formed with filters and other accessories. The shape of the projecting portions allows for the formation of progressive lenses or even custom shapes for users. The lens is also well-adapted for protective eyewear and sport goggles. The lens can be formed by co-molding separate projecting portions with a first lens portion, resulting in a significantly improved visual experience and function compared to a single unitary lens.
Problems solved by technology
It was unexpectedly found during experimentation with forming the lens device herein with the raised portions forming corrective lenses, that linear intersections of the perimeter of the raised portion, rather than minimizing optical refractions and light transmissions, actually caused such.

Embodiment Construction
[0051]Now referring to drawings of FIGS. 1-14, where similar structures are described with like numerals, there is seen in FIG. 1 a view of the unitary device 10 and method herein, showing the first surface 12 of a first lens portion 14 which has one, or as shown, a plurality of raised portions 16 extending from the first surface 12. The raised portions 16 have a shape defined by a perimeter sidewall17 extending from first side 19 which is ground for user lens requirements, to an intersection 18 with the first surface 12 in the formed unitary structure of the device 10. Also shown are the preferred curve or radius R2 at the intersection 18 of the sidewall 17 and the first surface 12 of the first lens portion 14 in the preferred radius noted above.
[0052]Extending from one side edge of the first lens portion 14 is shown a removable tooling member 20. It has been found in experimentation, that the tooling member 20 can be engaged with a grinding machine used to grind the individual pro...

Abstract
A unitary lens structure and method yielding a lens for eyewear formed to a unitary structure of a first lens portion and projecting portion adapted for grinding to a prescription lens. The unitary lens can include filtering material or layers only in the projecting portion or in both the projecting portion and first lens portion. Such structure is provided through forming the projecting portions to cured optical material first, and then positioning them in a mold for the first lens portion to be formed in the unitary structure upon curing of heated material forming the first lens portion.
Description
[0001]This application claims priority to U.S. Provisional Patent Application, Ser. No. 62 / 344,787, filed on Jun. 2, 2016, which is incorporated herein in its entirety by this reference thereto.BACKGROUND OF THE INVENTION1. Field of the Invention[0002]The present invention relates generally to corrective lenses employed in eyewear such as eyeglasses, protective eyewear, and goggles. More particularly, the disclosed eyewear device and method for forming such, relates to a first lens portion of optically correct material which is formed as a unitary structure with one or a plurality of rearward positioned projections formed of optically correct material, and wherein the perimeter edge of the first lens portion is configured for engagement in an eyewear frame or goggle or other lens frame, and where each projection is either pre-ground or may be subsequently ground to form a prescription lens.2. Prior Art[0003]Individuals with eyesight problems have turned to corrective eyewear for hun...
