1. A method for reducing progression of myopia in a human child having, or suspected of having, myopia, the method comprising:
identifying the human child having, or suspected of having, myopia; and
treating the human child with spectacles comprising at least one myopia control spectacle lens, wherein the myopia control spectacle lens comprises (i) a clear aperture, and (ii) a surrounding annular region, both (i) and (ii) substantially centered on a lens axis, the clear aperture corresponding to the central region and the annular region corresponding to the peripheral region and comprising a plurality of spaced apart scattering centers sized and shaped to scatter incident light, and
wherein said myopia control spectacle lens provides normal visual acuity to the human child when viewed through a central region of the lens and reduced visual acuity for the when viewed through a peripheral region of the lens, and wherein said myopia control spectacle lens reduces myopia progression in the human child by 0.4 D or more after three years of treatment compared to a control group.
