Abstract
An eyeglass device configured for use with a smart eyewear near-to-eye display includes a pair of lenses having a prism which directs an eye's gaze of the wearer to a first power region to focus an image displayed by the near-to-eye display of the smart eyewear and a second power region to focus an image outside or beyond the near-to-eye display of the smart eyewear; and a method for optimizing the visual acuity of a wearer of smart eyewear when observing an image generated by a near-to-eye display and an image outside or beyond the near-to-eye displayed image.
