New lenses address symptoms related to colorblindness, dyslexia
LAS VEGAS – A system of colored lenses is available to help relieve symptoms associated with color-blindness and visual reading disorders associated with dyslexia.
Executives from ChromaGen told PRIMARY CARE OPTOMETRY NEWS here at the International Vision Expo and Conference that the technology has been proven to help people of all ages who suffer from color deficiency and symptoms such as blurry, irregular or moving text, loss of focus or shifting words, letters or spaces when reading.
ChromaGen vice president of sales Doran Roberts told PCON that the diagnostic set is made up of 16 filters. The nondominant eye is tested first. Once a filter is identified that reduces or eliminates the visual symptoms, the dominant eye is then addressed.
ChromaGen chief executive officer Ted Edwards said the technology is available in plano lenses, single vision lenses, contacts and clip-ons. “Ninety-eight percent of patients will be helped with this technology,” he said.
Mr. Edwards said patients often experience headaches, nausea and fatigue without the lenses. With the lenses, prescribing doctors are seeing reading speed and accuracy improving along with handwriting and self-esteem.
The ChromaGen system was invented by David Harris, PhD. It is under patent in the US until 2025.
