Enhances your vision quality by minimizing an optical imperfection* commonly found in eyes.1

Aberration Neutralizing System™

For illustrative purposes only 

The surfaces of your eyes are not perfectly spherical. There are natural imperfections in the curvature of each eye’s cornea and lens that can reduce your vision quality.2,3 Your eye care professional calls this spherical aberration.

These naturally occurring imperfections can cause incoming light rays to focus at multiple points. This can create a blurred image, especially in low light conditions, because the eye’s optical system doesn’t have a single point of focus.

Thanks to the Aberration Neutralizing System™, the lens’s front surface design is customized for your prescription to help neutralize the impact of spherical aberration in the eye. As a result, incoming light rays converge for better focus and sharp vision.

Benefits:

Visual acuity

Designed for a single point of focus and sharp vision
