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.

Focused on the fovea

The fovea is where clear vision occurs.

  • To enhance vision with the NaturalVue® Multifocal lens, adding minus moves the focal point closer to the fovea
  • With Neurofocus Optics® and EDOF technology, a RANGE of clear vision can be delivered simultaneously

The key to delivering the best vision is to move the focal point along the visual axis closer to the fovea

The Neurofocus Optics® difference

This unique technology creates pinhole optics which results in an extended depth of focus, delivering a wider range of clear vision along the visual axis.
