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.

Abstract: An improved method for configuring progressive ophthalmic lenses is disclosed. The method includes computing an improved merit function that modulates reduction of peripheral values of the mean sphere according to the prescription sphere. According to the method the amount of reduction of mean sphere of the lens peripheral regions is dependent on the prescription resulting from a modified merit function. As such, the reduction of peripheral mean sphere varies based on the prescription. According to the modified merit function and resulting improved merit function, the greater the hyperopia and/or presbyopia defined in a prescription, the smaller the reduction of the peripheral value of mean sphere. Accordingly, when the peripheral mean sphere reduction is relaxed, a near region is made wider.

Abstract: An improved method for configuring progressive ophthalmic lenses is disclosed. The method includes computing a traditional merit function with two changes. First, the merit function computation is limited by calculating only a preferred distance from the meridian rather than until 0. Second, an additional term is added to the merit function that calculates the mean sphere at a point that is at a reduced range from the maximum unwanted cylinder, rather than the entire range.
