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.
Progressive lenses have become very popular these days as they offer a more natural field of vision than bifocal and trifocal lens types do. By definition, progressive lenses can also be categorized as a variety of aspheric lens due to the gradient nature of the lens.
