本发明涉及一种双面复合新优学聚氨酯镜片的制造方法,镜片的内外表面面型均采用同心圆结构设计,在不同直径的圆环层状结构内部有两个屈光度,面上屈光度基于矫正视力屈光不正用的处方的屈光度,在凸面上分布着多个彼此独立的凸起圆顶,凸起圆顶屈光度比平面屈光度有+0.25-+2.50D的加光,在凹面上分布着多个彼此独立的凸起圆顶,凸起圆顶屈光度比平面屈光度有+0.25-+2.50D的加光,凸面和凹面上凸起圆顶是一一对应的。镜片表面的同心圆个数在3-10个之间。圆环的直径在0.5mm到40mm之间。本发明的采用双面同心圆结构,凸起圆顶的屈光度加光范围为+0.25-+2.50D为离焦镜片在佩戴上提供更好的舒适度。

The invention relates to a manufacturing method of a double-faced composite new-excellent polyurethane lens. Each of an inner surface type and an outer surface type of the lens adopts a concentric circle structure design, two diopters are existent in the circular layer structures with different diameters, the surface diopter is based on the diopter of the prescription not used in the vision refraction correction, multiple mutually independent convex round tops are distributed on the convex side, and the diopter of the convex round top has +0.25 to +2.50D light adding in comparison with the diopter of the plane; multiple mutually independent convex round tops are distributed on a concave side, the diopter of the convex round top has +0.25 to +2.50D light adding in comparison with the diopter of the plane, the convex round tops on the convex side and the concave sides are corresponding one-to-one. The number of the concentric circle of the lens surface is between 3-10, the diameter of the circular ring is between 0.5mm to 40mm. By adopting the double-faced concentric circle structure, the diopter light-adding range of the convex round top is +0.25 to +2.50D, and better comfort levelis provided for the wearing of the defocused lens.
