Optical frame glasses
View Patent ↗The present application discloses optical frame glasses, comprising lens. The lens has a circular central area and a plurality of annular focus-increasing compensation areas surrounding the central area, the center of the circular central area coincides with the optical center of the lens, wherein focal powers of the central area and the plurality of focus-increasing compensation areas progressively increase in a radially outward direction. The optical frame glasses in the present application can eliminate high-order aberrations of eyes, thereby limiting the occurrence and development of myopia. In addition, the optical frame glasses of the present application do not touch the eyeballs, the wearing method is simple, no discomfort is caused after worn, the maintenance method is simple, and the manufacturing cost is low.
1. Optical frame glasses comprising a lens, wherein the lens has a circular central area and a plurality of annular focus-increasing compensation areas surrounding the central area, wherein the center of the circular central area coincides with the optical center of the lens, and wherein positive focal powers of the central area and the plurality of focus-increasing compensation areas progressively increase in a radially outward direction;
wherein the lens has five focus-increasing compensation areas of equal width, wherein the diameter of the central area is 2 mm, and wherein the ring width of each of the focus-increasing compensation areas is 2 mm; and
wherein the increasing values of the positive focal powers of the five equal-width focus-increasing compensation areas, which are arranged successively in the radially outward direction, relative to the central area are 0.01D, 0.03D, 0.07D, 0.12D, and 0.18D, respectively.
2. The optical frame glasses according to claim 1 , wherein the central area and the plurality of focus-increasing compensation areas constitute a static field of view of the lens.
