ABSTRACT:
A specialty eyewear device including an optical frame that carries a pair of highly reflective surfaces that permit a wearer to experience an angular offset between the direct line of vision and the effective line of vision. No refraction occurs in the performance of the device, and no image reversal takes place. Modifications of the invention allow for certain angular adjustments in the device which can both change the actual angular offset which occurs between direct and effective line of vision, and permits angular rotation of a given angular offset.
