Simultaneous Multifocal

Front Surface Aspheric Design

The Asphero-F is a simultaneous-vision multifocal design that combines a spherical back surface with a low-eccentricity aspheric front curve. 

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.
