Abstract
Systems and methods for creating ophthalmic lens creation instructions are disclosed. The method includes obtaining an ophthalmic prescription and preparing lens creation instructions based on the ophthalmic prescription including determining a baseline lens design. The lens creation instructions are augmented to reduce myopia. The augmented lens creation instructions are created by determining a central region and a peripheral region in the baseline lens, computing a distortion pattern of bumps randomly located in the peripheral region of the lens such that the bumps have random sizes and random strengths, wherein the location, size and strength are created using probability distribution functions, and then computing a final back surface of the lens including incorporating the distortion pattern of bumps into the baseline lens. A lens created by this method is described herein. The method may be implemented on a computing device.
