EYEGLASS DISPLAY LENS SYSTEM EMPLOYING OFF-AXIS OPTICAL DESIGN

摘要

An off-axis optical display system is provided. The system comprises an eyeglass lens assembly having the first lens section (30) having a first surface (40), at least a portion of the first surface having a first curvatu re (25), and a second lens section (20) having a second surface (40), at least a portion of the second surface having a second curvature. The interface comprises an optical layer and conforms to the first curvature of the first surface and the second curvature of the second surface (25). An image source (50-52) is located off-axis with respect to the interface to transmit light along an optical path (10) that reflects off the optical reflective surface (25) 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 (36). An aberration correction element is also provided ( 31- 32).
