Abstract:
Systems and methods for creating and/or manufacturing progressive lenses (e.g., bifocal, multifocal, and so on) having ocular side (e.g., back side or surface) lens segments, are described. For example, the systems and methods may apply round lens segments to ocular sides or surfaces of progressive lenses, providing the lenses with specializing vision lens segments and/or power enhancement lens segments, which may combine with front surface power additions provided by the multifocal lens segments applied to the front surfaces of the lenses.
