Abstract
An off-axis optical display system is provided. The system comprises an eyeglass lens assembly having a first lens section having a first surface, at least a portion of the first surface having a first curvature, and a second lens section having a second surface, at least a portion of the second surface having a second curvature. An interface is located between the first surface and the second surface. The interface comprises an optical layer and conforms to the first curvature of the first surface and the second curvature of the second surface. An image source is located off-axis with respect to the interface to transmit light along an optical path that reflects off the optical reflective surface of the interface toward an eye of a user. A portion of the optical path may be through air, and refraction is provided at the interface between air and the first lens. An aberration correction element is also provided.
