Title:
PERIPHERALLY DEFOCUSED FRAME GLASSES LENS HAVING FUNCTIONAL AREAS OF ASYMMETRIC CORRECTIONS
Document Type and Number:
WIPO Patent Application WO/2016/000440
Kind Code:
A1
Abstract:
A peripherally defocused frame glasses lens having functional areas of asymmetric corrections. The lens is a frame glasses lens or a press-on lens, and is provided with a central optical region (2), a nasal side functional region (3), and a temporal side functional region (4). The central optical region (2) is prepared with a plano lens (6) or a concave lens (7). The nasal side functional region (3) and the temporal side functional region (4) are respectively provided at the nasal side and the temporal side of the central optical region (2), and are prepared with a single region refractive lens, a tri-region refractive lens, or a progressive refractive lens with different positive degrees. The nasal side functional region (3) is greater than the temporal side functional region (4) by +0.10D to +1.50D, and is prepared with a plano lens (6), a concave lens (7), or a convex lens (8).
