Developed using AI-driven technology, Chemistrie Color lenses assist with the perception of color in those with color vision deficiency (CVD). Instead of relying on heavy red or pink tinted lenses, Chemistrie Color lenses enhance genuine color vision. Patients experience the truest possible discernment of color.

Red lenses rely on heavy tinting that helps patients distinguish colors but also shifts their entire color spectrum so everything has a red hue. Chemistrie Color lenses are modified in the specific part of the visible light spectrum where patients with CVD are deficient. With Chemistrie Color lenses, patients can see truer color. White remains white and no colors are artificially darkened.


  • A – Indoor: for patients who will use the lens mostly indoors
  • B – Outdoor Moderate: for patients who are light sensitive indoors or want a lighter outdoor tint
  • C – Outdoor Severe: for patients who want an outdoor lens and suffer from light sensitivity


Fitovers are a convenient option for patients who use prescription glasses but don’t need to wear a medical tint full-time. Fitover options may be right for your patients if they:

  • Want colorblind lenses as fast as possible
  • Wear multiple pairs of glasses and need a solution that works with all frames
  • Prefer fitovers to clip-ons
  • Need the most affordable option
  • Can’t or don’t want to send their frames in for clip-ons to be made

If you need assistance finding the right frames, determining if a fitover model is available, or what tint is best for your patient, give us a shout. We’re happy to help you in any way that we can.
