Abstract: The disclosed ophthalmic lens includes a posterior surface and an anterior surface having a spherical central optical correction zone, an aspheric intermediate zone, and a peripheral zone. The intermediate and peripheral zones are not used for optical correction. The posterior surface includes a central optical zone, an intermediate zone, and a peripheral zone. The central optical zone of the anterior surface has a larger diameter than the central optical zone of the posterior surface. Similarly, the intermediate zone of the anterior surface has a larger diameter than the intermediate zone of the posterior surface. The inventive construction is particularly beneficial when applied to a rigid contact lens, particularly rigid contact lenses made using a high DK material.
