Aspheric Multifocal Contact Lenses
These multifocal contact lens designs work more like progressive eyeglass lenses, where the different prescriptive powers are blended across the lens. Unlike eyeglasses, however, aspheric contact lenses are simultaneous vision lenses, so your visual system learns to select the proper prescription for the moment.
This is the only type of multifocal contact lens that can be described as "progressive." It has a concentric ring design, (a circle within a circle) and it has become the most popular type of multifocal contact lens.
