An aspheric lens or asphere is a lens whose surface profiles are not portions of a sphere or cylinder. In photography, a lens assembly that includes an aspheric element is often called an aspherical lens. The asphere's more complex surface profile can reduce or eliminate spherical aberration and also reduce other optical aberrations such as astigmatism, compared to a simple lens.
Called also diverging lens. contact l's corrective lenses that fit directly over the cornea of the eye; see also contact lenses. converging lens (convex lens) one curved like the exterior of a hollow sphere; it brings light to a focus. convexoconcave lens one that has one convex and one concave face.
