Carl Zeiss Vision (CZV) has developed their newest progressive lens called GT2 3D Asiana. The lens design is an enhanced progressive for the Asian face. The craniometry, or the underlying bone structure of the head and face, has a marked difference between Caucasian and Asian populations. Often, the cheek structure of the Asian face has a flatter profile and the bridge of the nose is less pronounced. These two factors combined reduce the amount of Pantoscopic Tilt and the degree of Bow Angle found in Asian wearers. Contact your CZV rep for details.
