Abstract
A progressive spectacle lens design has clear focal properties in the entire lens, and progressive variation in focal properties from the center of the lens down into a reading area. All current conventional progressive lenses have areas of distortion to the side of the reading area. The present invention provides undistorted optical viewing throughout the entire lens, although the focal length varies.
