主权项 1. An ophthalmic lens comprising a design that includes correction factors for near and far vision based on wavefront data and pupil size wherein said the use of the lens slows or stops the progression of myopia, the ophthalmic lens comprising: a convex surface with a central optic zone surrounded by a peripheral zone further surrounded by an edge zone; and a concave surface which rests on the wearer's eye, wherein the lens power at any location in the optical zone is described by the sum of the apical distance averaged wavefront derived power plus a correction which is derived from a single, partial multiple or multiple of the difference between the distance and near average wavefront derived power at each location (x) and the difference between the apical near and distance wavefront derived powers, the optical lens power being useful in controlling or slowing the progression of myopia, the lens power being described by PowProf=RPD(0)+k(x)((RPD(x)+(RPN(0)−RPD(0)))−RPN(x)),wherein RPD(x) is the average wavefront derived distance refractive power measured at distance at a ray height x, RPN(x) is an average wavefront derived near refractive power measured at near at a ray height x, k(x) is any suitable mathematical function including at least one of a constant multiplier with a range of between 0.25 to 4, or varies with x as with an inverse Stiles Crawford effect, RPD(0) is the average wavefront derived distance apical refractive power, and RPN(0) is the average wavefront derived near apical refractive power measured at near at a ray height x.
