Key Takeaways
- Ishihara test sensitivity 95% for protan/deutan genetics screening
- Farnsworth-Munsell 100 Hue test discriminates anomaly severity with 90% accuracy
- Anomaloscope gold standard, matches Rayleigh equation in 99% congenital cases
- X-linked inheritance causes 99% of color blindness cases to be male
- The OPN1LW gene on X chromosome is mutated in protan defects
- OPN1MW gene mutations cause deuteranomaly in 98% of cases
- Color blindness reduces contrast sensitivity by 15% in traffic lights
- 40% of color blind individuals struggle with fruit/vegetable identification
- Pilots with mild defects have 25% higher error in signal recognition
- Approximately 8% of men and 0.5% of women worldwide suffer from red-green color blindness
- In the United States, color blindness affects about 1 in 12 men (8.3%) and 1 in 200 women (0.5%)
- Caucasian males have a higher prevalence of color blindness at 10.4% compared to 4.3% in African males
- Gene therapy trials restore 20-30% cone function in primates
- EnChroma glasses improve discrimination by 55% for deuteranopes

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
