Abstract: A multipart sunglass device includes a frame having an integrated nosepiece. A semitransparent, polycarbonate sunglass lens is mounted to the frame. The frame completely encloses a side surface of the sunglass lens. The sunglass lens extends vertically from a top surface of the frame to a first position corresponding to a location just below the pupil of the eye of a wearer. A transparent, refractive lens is coupled to a bottom surface of the sunglass lens corresponding with the first position. The sunglass lens and the refractive lens are joined at a distinct separation zone, allowing the wearer to view objects having a focal position lower than the first position without any obstruction, filtration or absorption of light, yet view the objects subject to a refractive property of the refractive lens.

Abstract: An apparatus for light filtration is disclosed. The apparatus has a support structure. A lens is coupled to the support structure. The lens includes a first portion for performing light filtration, and a second portion. The second portion performs substantially less light filtration than the first portion or performs no light filtration. A distinct separation zone can be located between the first portion and the second portion. An apparatus for light filtration having an associated viewing area is disclosed. The apparatus includes a support structure, and a lens coupled to the support structure for performing light filtration. A portion of the lens is cut-out to allow for a portion of the viewing area to receive no light filtration. A method of making the same is disclosed.
