Color Overlays vs. Color Filtered Lenses

Today we’re going to share with you what color overlays are, what color-filtered lenses are, how they are different, and why the color-filtered lenses from ChromaGen are a better option.

What are Color Overlays and How Do They Work?

Color overlays work by changing the wavelength of the light in order to make the print clearer for the reader. These overlays were developed for people with reading problems or dyslexia. Overlays are not contact lenses, they are plastic sheets that the reader simply places over the page.  These overlays have also been used by adults and children on computer screens to reduce eyestrain by strengthening the print on the screen.

Color overlays use the same color for both eyes, which means that if the reader were to have a different strength in each eye, these overlays wouldn’t be so effective. Overlays also use a combination of colors, which produces a muted and muddled color to get their effect.   Overlays are plastic, so they have waves and distortions in the material, which can make it possible for some readers to not get a clear view at all.

What are Color Filtered Lenses and Why are They Better?

Color-filtered lenses, which are color-tinted lenses, were originally developed to help those that are color blind.  However, it was discovered that these lenses were also an effective solution for individuals that were struggling with reading.  A second generation of these lenses was developed solely to help those struggling with reading problems and dyslexia. The print becomes clearer and it helps those with reading problems or dyslexia to read faster and more effectively.  ChromaGen Lenses stop words from moving and for those that struggle with reading problems and dyslexia a common response from users is, “this is the first time I have seen words that stand still and don’t move on the page!”  Words are no longer blurry, headaches, stomachaches and fatigue are gone and our patients now look forward to reading.  But, what makes them work better then colored overlays?

Color-filtered lenses were developed with struggling readers in mind, and because of this, ChromaGen employs haploscopic testing and prescribing. This is done for two main reasons. Both eyes are not always the same, thus it’s important to make sure that both eyes are open during the entire prescribing process and each eye is prescribed individually to ensure that the optimum color is prescribed for each eye.

ChromaGen uses precise hue, saturation, and brightness values to achieve optimum results. Last but not least, plastic color overlays have distortion; while the ChromaGen colored filtered lenses are made from the highest quality optical grade materials with no distortions.

The difference between the two is significant, making ChromaGen the most effective and stable choice, producing more consistent results for struggling readers.

How does one train as a Chromogen screener and how much does it cost?
