本发明涉及一种GovernMyo聚氨酯镜片的制造方法,其特征在于,镜片表面面型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‑+5.00D的加光;凸起圆顶的设计为高阶非球面设计。本申请的采用同心圆结构,为镜片离焦设计提供了多种选择的可能性;除了近视患者的眼球的周边近视性离焦,部分光线成像于视网膜之前,从而有效地延缓青少年近视的加深。同心圆结构可以很好解决眼动带来了离焦效果变差的问题。
The invention relates to a method for manufacturing a Govern Myo polyurethane lens. The method is characterized in that: the surface type of the lens adopts a concentric circle structure design, two diopters are arranged in circular ring layered structures with different diameters, the diopter on the surface is based on the diopter of a prescription for correcting ametropia of vision, a plurality of mutually independent convex domes are distributed on the surface, and the diopter of the convex domes has plus light of +0.25-/+ 5.00D compared with the diopter on the surface; the design of the convex domes is a high order aspheric design. The concentric circle structure is adopted, and multiple choices are provided for the defocusing design of the lens; except peripheral myopic defocus of eyeballs of a myopic patient, part of light rays are imaged in front of retinas, so that the progression of myopia of teenagers is effectively delayed. The concentric circle structure can well solve the problem that the defocusing effect is poor due to eye movement.
