Efficacy of ChromaGen lenses in enhancing color perception in color vision deficiency: a critical evaluation
Abstract
Aims: Despite advancements in color vision correction, evidence supporting the efficacy of ChromaGen haploscopic filter systems in improving color perception remains limited. This study primarily investigates the performance of ChromaGen lenses (CL).
Methods: The study included 27 volunteers diagnosed with color vision deficiency (CVD). An anomaloscope was used to detect color vision defects. Participants underwent color vision tests (Ishihara and Panel D15) both with and without CL. The results were statistically analyzed.
Results: All participants were male, aged 21 to 57. Among them, 12 (44%) had protan defect (10 protanopes, 2 protanomalies) and 15 (56%) had deutan defect (12 deuteranopes, 3 deuteranomalies). Without CL, protan defect participants read 2.0±1.0 pages on the Ishihara test, while deutan defect participants read 3.0±1.9 pages. With CL, protan defect participants read 4.5±2.2 pages and deutan defect participants read 14.2±0.9 pages, showing statistically significant improvement (p<0.05). The difference between protan and deutan groups was also statistically significant (p<0.05). In the Panel D15 test, without the use of CL 81% of individuals with protanopia and deuteranopia made significant errors, whereas participants with protanomaly and deuteranomaly performed well. No significant improvement was noted with CL in the Panel D15 results. Twenty-three participants preferred magenta and four preferred pink CL. Fifteen participants expressed interest in using CL solely to pass the Ishihara test.
Conclusion: This study concludes that commercially available ChromaGen filters do not provide clinically significant evidence of improved subjective color perception. Therefore, recommending these devices to the CVD population for color perception may not be highly beneficial. However ChromaGen lenses may be used by some CVD patients to pass the Ishihara test.
