Clip-On and Fitover Solutions for Color Vision Deficiency

Chadwick Enliven

The Lens Technology

Chemistrie Color was developed by color scientists to specifically enhance the colors most challenging to patients with red-green or blue-yellow color vision deficiency.

Instead of relying on heavy red or pink tinted lenses, Chemistrie Color provides patients with the truest possible discernment of color and enhances genuine color vision. Each severity level works for protan, deutan, or tritan color vision deficiency without requiring separate lens colors.

Chemistrie Color can fit over an Rx but is not available as an Rx lens.

Seeing Color in a New Light

Using the latest in color vision technology, Chemistrie Color lenses help your patients see color like never before. Use our simulation tool below to compare normal vision with different color vision deficiencies.

Lens Color Options

Lenses are available in three color options depending on your patients’ needs and the severity of their color deficiency.

A – Indoor

Indoor lenses are the lightest solution and are suited primarily for indoor use.

B – Outdoor Moderate

Outdoor Moderate lenses are medium-colored and suited for indoor use for patients with light sensitivity and for outdoor use.

C – Outdoor Severe

Outdoor severe is the darkest lens option available and is suited for outdoor use for patients with light sensitivity.

Lens Fit Types

Chemistrie Color lenses are available as custom-made Chemistrie clip-ons or ready-made fitovers.


Clips-ons use Chemistrie technology to attach custom-made clip-ons using micro magnets embedded in the primary Rx lens.

Clip-ons can be made to fit almost any frame your patient wants.

Some benefits of clip-ons include:

  • Base curve matched: available in 2, 4 and 6 base curves custom-fit to patient RXs
  • Lightweight: made from ultra-thin polycarbonate lens material
  • Anti-Reflective Coating: reduces unwanted glare

Our ready-made fitovers are a handy way to help your patients address their color vision deficiencies. Available in the same color options as clip-ons, fitovers offer the best combination of value and convenience.
