SEIKO Supercede II lenses use a universal blended design that provides wide distance vision and an extra wide reading area. It is a good choice for emerging presbyopes, as well as experienced wearers, and is ideally suited for all add power prescriptions and for those with visually demanding lifestyles.
Advanced aspheric compensation (AAC) in the intermediate and near visual zones optimizes the optical performance in the as-worn position. AAC alters the surface power to deliver the prescribed power when the lens is positioned in front of the eye. It also reduces aberrations caused by varying vertex distance and compensates for pantoscopic tilt as the eyes converge from the fitting point to the reading area. This "measured power" is printed on the job envelope for easier verification.
