Abstract
A contact lens for use in preventing or slowing the development or progression of myopia, and methods of manufacturing and using such a lens. The optic zone of the lens comprises a central region having a curvature providing a base power. The optic zone comprises an annular region circumferentially surrounding the central region. The annular region comprises a treatment zone having a characteristic that reduces the contrast of an image of an object that is formed by light passing through the central region and the treatment zone compared to an image of an object that would be formed by light passing through only the central region. The characteristic that causes the contrast reduction varies with meridian around the annular region. A peripheral zone surrounding the annular region has a constant thickness profile in every meridian or a variation in thickness configured to promote rotation of the lens.
