SEIKO Supernal is an individualized lens design that utilizes patented "Internal progressive + Internal Aspheric design." Supernal modifies the Rx to achieve an optically precise correction in the as-worn position. This compensation factors in eye rotation, vertex distance and frame tilt. The benefit to the wearer is improved clarity and visual comfort throughout the entire lens, with expanded peripheral vision, even in high-cylinder, high-add Rx's.
