Abstract:
To provide a lens that has an improved optical configuration in order to provide enhanced off-axis optical performance by contributing to reducing, eliminating or minimizing first-order optical distortion.SOLUTION: Embodiments may be used in non-corrective or corrective single or dual lens eyewear, e.g., in combination with a frame to support a lens in a path of a straight ahead line of sight forming a center axis of an eye of a typical wearer. The lens comprises a lens body. The lens body may comprise a surface having a spherical, toric, cylindrical or freeform geometry, and another surface having a freeform geometry. A lens thickness is defined between the surfaces. A prismatic power of the lens is improved, particularly for off-axis viewing angles.SELECTED DRAWING: Figure 6
