SAN ANTONIO–(BUSINESS WIRE)–February 7, 2022–
The Rosenberg School of Optometry at the University of the Incarnate Word (UIWRSO) is proud to announce the publication of a groundbreaking new study which has found that special EnChroma glasses, designed with technically advanced spectral notch filters, improve color vision for those with the most common color types. visual impairment. It should be noted that the colorblind test subjects experienced an immediate improvement, which persisted in the long term even after the subjects stopped wearing the glasses.

Normal color vision, based on three cones sensitive to red, green and blue light, is essential for critical color discrimination in several professions and for learning in school. Yet 8% of men and 0.5% of women have inherited color vision deficiency, or about 13 million in the United States and 350 million worldwide.
In the study, thirteen color-blind subjects received the special color-correcting lenses developed by EnChroma and wore them daily for 11 to 14 days. Cone contrast sensitivity and color naming were then assessed by presenting subjects with colored letters visible only to red, green, or blue cones. With the glasses, subjects showed immediate improvement. After 12 days, the improvement in color vision was maintained even without wearing glasses.
Most importantly, building on previous research, the study found immediate and long-term improvement in color threshold (lowest detectable color contrast) as well as above-threshold measurements (easily visible to color blind), including color naming and visual brain waves (VEP) with the stimulus visible only to the red, green or blue sensitive cones. The immediate and long-term selective (cone-specific) enhancement of VEPs with EnChroma lenses suggests that they enable stimulation of brain areas critical for color vision. Since color blind people cannot properly receive signals from specific color cones, the results indicate that EnChroma glasses activate the neural mechanisms necessary to see colors better and improve and expand color vision for those with color impairments. red-green color vision.
“Our results indicate that EnChroma lenses may improve color vision and quality of life in some individuals with color vision deficiency,” says Dr. Jeff Rabin, Professor and Associate Dean of Graduate Studies, Research and evaluation at UIWRSO. “For example, a 66-year-old man with severe protanomal deficiency (red cone) was overjoyed to see better the tomatoes in his garden, a full rainbow, as well as the colors of the cars (in especially the reds and blues) that ‘pop’ when he drives. On a recent six month visit, a 3-5x improvement in daytime and outdoor color vision was recorded. We look forward to continuing this exciting research.
People with standard color vision see over a million hues and shades, while red-green color blind people see only about 10%. For those with color vision deficiency, colors appear muted, sometimes confusing, and some colors are difficult to differentiate.
The study was conducted by Dr. Jeff Rabin, Frances Silva, Natalie Trevino, Harper Gillentine, Liqing Li, Loary Inclan, Gary Anderson, Erica Lee, and Harrison Vo.
