Abstract
Aspheric corneal contact lenses are used to treat myopia by controlled corneal molding. In one embodiment of the method, the lens includes an asymmetric central zone which provides multiple focusing capability to correct both near and far vision. A tear zone is located concentrically around the central zone. The tear zone is integral with the central zone and has a radius of curvature which is smaller than the central zone. The lens also includes a peripheral zone located concentrically around the tear zone wherein the peripheral zone has a radius of curvature equal to or greater than the central zone.
