摘要: Optically superior eyeglasses comprising a frame and pair of lenses which are attached to the positionable over respective ones wearer's eyes. Each defines an optical center comprises convex front surface having first radius curvature concave back second is less than so as impart negative power lens. The sized configured such that when positioned upon head, supported thereby in manner wherein normal line sight each eyes crosses one at selected wrap angle location nasal thereof induce base-in prism effect.
