ASPHERO - FB

  Simultaneous Multifocal

Bi-Aspheric Design

The Asphero-FB is a simultaneous-vision multifocal design that combines a low- eccentricity base curve with a low-eccentricity front surface.

This design provides progressive add power from the center of the lens to the periphery, offering a valuable alternative to the fitting challenges that can arise with concentric, tangential and crescent-segmented translating designs.

While this lens requires absolute centration to produce the simultaneous-vision effect, it produces good intermediate acuity. As a result, this lens is often preferred by patients whose professions or lifestyles cause them to spend time reading computer screens.  

Diameters:      8.50 mm to 10.0 mm

Base Curve:    6.50 mm to 8.44 mm

Distance:         -20.0 D to +6.00 D

Add Power:     +0.75 to +3.00 D
