Technical Examples

It has been difficult to manufacture an inside surface progressive-power lens which is as thin as an outside surface progressive-power lens due to a limited configuration of an object-side refractive surface of the inside surface progressive-power lens. However, a thin progressive-power lens with less blur and distortion can be provided at a reduced cost by forming its object-side refractive surface from an aspherical surface which is symmetric with respect to a rotational axis and has a smaller curvature at a distance reference point than that at a near reference point, and by forming an eyeball-side refractive surface from a combination of a progressive surface, an astigmatic refraction surface and an "as-worn" corrective aspherical surface.
