What is ChromaGen®


ChromaGen® is a patented lens technology for the treatment of reading problems. It is non-invasive and does not involve surgery or chemicals and therefore has none of the traditional risks associated with medical devices and procedures.

Words Move on The Page

Dr. David Harris, who developed the ChromaGen Lenses has concluded that, "Reading problems are the single most detrimental condition that has a negative impact on the learning process. ChromaGen Lenses can provide a benefit for the majority of students that struggle with reading. The key is to identify those students that see words that move on the page or struggle with headaches, nausea, and fatigue. These are the people that we help."


Do you see words moving on the page?

Individuals that struggle with reading problems or dyslexia often describe words that appear to move when reading. They state that 1) words are blurry or come in and out of focus, 2) words move up and down or from side to side, 3) words appear to “float” on the page, 4) words “scrunch together” or “pull apart,” 5) they see double words or double sentences or 6) the spaces in between the lines “move” or “float. “ They often say that they simply do not want to read; it is just too frustrating. Users of ChromaGen Lenses report that all of these word movement symptoms simply stop and they no longer get headaches, nausea or fatigue.

Why are the words moving when I read?

The light-sensitive receptors in your eyes interpret light and convert the image projected onto the retina into a signal that is sent along the visual pathway (neurological pathway) to the brain. The light traveling into your eyes along the optic nerve to the brain is not balanced. This causes words to move.

The left side of the brain processes light information from the right eye and the right side of the brain processes light information from the left eye. As each eye processes light differently, the signals sent from each eye reach their respective locations in your brain at a different time.

In addition to your eyes processing light differently, light that is transmitted to the brain also travels at different speeds and is processed at different speeds. This causes the eyes and the brain to be out of sync with each other. This is why words appear to be blurry, out of focus, or move in some way. People also describe the spaces in between the lines appear to move or float.

Different Colored Lens for Each Eye

A lens can also be referred to as a filter. A filter is a substance or device that prevents certain elements from passing through it while also allowing certain elements to pass through it. Each of the 16 ChromaGen Lenses has a precise color, saturation, and brightness value imbued into it.

As every color has a different wavelength and every ChromaGen lens is a different color, the speed of the neurological transmission from the eye to the brain changes with every different ChromaGen Lens. Everyone will need to be evaluated at a ChromaGen Certified Eye Doctor to determine which one of the 16 ChromaGen Lenses will be the most optimal for each of their eyes.

Simply put, the proper application and use of precisely tinted ChromaGen Lenses integrated into a contact lens or eyeglass modality slows down the wavelength of light and provides the proper luminance to effectively balance the visual system enabling users of ChromaGen Lenses to read with ease.

The Solution: ChromaGen Lenses


When the ChromaGen lenses are prescribed for each eye, the light is slowed down to the "right" speed for each eye. The result is that both eyes are then working together as a team to send the proper signal to the brain. The signal that is sent from the eyes along the neurological pathways to the brain is now balanced causing the brain to process the information more efficiently or more accurately. The net result is that the text is clear and the words stop moving.

When wearing ChromaGen Lenses, people report that all the symptoms of words moving simply stop. When a person is prescribed ChromaGen lenses, the result will be instantaneous. They will immediately see the difference of clear text and words no longer appearing to move on the page. ChromaGen users also report a significant reduction in headaches, nausea, and fatigue.

Reading is dependent on the precise synchronization of the Parvocellular (P-cell) and the Magnocellular (M-cell) pathways within the central nervous system and specifically the LGN (lateral geniculate nucleus). The reading process, with regard to the neural system, has its origination in the retinal ganglion cells and traverses via the LGN, to the visual cortex, striate, and extrastriate areas. Individuals with a reading disability have delays in the M-cell's pathway development or function. The introduction of a precise long wavelength ChromaGen lens provides the optimal reduction of wavelength and luminance to properly rebalance the M-cell system with the P-cell system.

Once you have evaluated ChromaGen and want to determine if you will benefit from ChromaGen Lenses, you can take the ChromaGen Survey.

  • * The survey is very accurate at pre-qualifying a candidate for ChromaGen Lenses.
  • * At the conclusion of the survey, you will get an immediate response via email.
  • * The email will indicate if ChromaGen will help with your Reading Problems or Dyslexia.
  • * The survey will take 3-4 minutes to complete.
