contact lens optics

The science behind our optics is what enables NaturalVue® Enhanced contact lenses to redefine how eye care professionals harness technology to better manage their patients’ vision needs.

The science of natural vision meets the science of NaturalVue®

Unlike single vision or traditional multifocal lenses, NaturalVue® (etafilcon A) Enhanced Multifocal contact lenses feature the Neurofocus Optics® design, which creates an extended depth of focus to deliver a wider range of clear vision. New NaturalVue® Enhanced Multifocal 1 Day™ contact lenses feature the same great design, with no refit required.

Neurofocus Optics® Technology creates an Extended Depth of Focus

Compare how today’s single vision or traditional multifocal contact lenses focus light vs. the extended depth of focus design of Neurofocus Optics® which allows multiple focal points along the visual axis to be clear.

Ray Tracing Modeling Simulates Light Through Lens & Eye

Ray tracing modeling was done to simulate what happens to light as it comes into the eye through various contact lenses designs.

These videos represent ray tracing modeling done by Jim Schwiegerling, former head of optics at University of Arizona, Phoenix. The defocused rays resulting from different lens designs are considered a foe for visual comfort and visual quality, but a great friend for progressing myopes and presbyopes. However, how it is delivered can significantly impact the visual experience.

The unique amount of plus power in NaturalVue® Enhanced Multifocal contact lenses is significant enough to induce peripheral blur. This generates the virtual pinhole aperture to create an Extended Depth of Focus.
