Fully Compensated Design, Backside Digital Free-Form Progressive

Description:

Universal Blended Aspheric design. Backside free-form processing with a spherical front surface, combine to provide patient-specific optical correction, with clear wide vision in all visual fields, and low distortion.

Target Patient:

FF-3-FX Progressive Lenses feature a blended soft design which is ideal for both emerging presbyopes and Experienced wearers. Choose the FF-3-FX for smaller frame sizes and more difficult Rxs, such as compensated fitting parameters for the “as worn” position. Compensates (measured power) in the intermediate and near zones based on pantoscopic tilt, vertex distance, and eye rotation.
