In contemporary frames, we have new challenges. First, smaller frames tend to be “flatter”. in larger frames, lenses often bulge out the front especially in plus powers. To make lenses bulge less and fit today’s flatter frames consider aspheric lenses.


Aspheric lenses that have been flattened to look better, see better, too. They have front surfaces that are “not-spherical;” they flatten towards the periphery in plus prescriptions and steepen towards the periphery in minus.

This change of curvature is calculated to correct for the peripheral blur that would be created when a flatter base curve is used that is not best form. Benefits for the wearer are the lens looks better in the frame and is less magnifying. Less magnification makes both the wearer’s eyes and the world that they see more natural in size.
