Abstract
Embodiments of the present invention relate to curved eyewear having an electrically switchable spectral transmittance lens. The lens is curved in orientation, which aids in reducing eyelash contact while increasing a peripheral field of view for a wearer of the curved eyewear. The electrically switchable spectral transmittance lens, in an embodiment, includes a plurality of zones that may be switched in-phase or out-of-phase with each other depending on an activity being performed. Another embodiment utilizes a shatter-resistant material for constructing the lens. Further embodiments utilize a frame member that includes a curved channel for forming the curved orientation of the lens and for maintaining the lens in a desired position relative to a wearer.
