What is a good Color Blindness Test score?
| Level | Score Range |
|---|---|
| Normal Vision | 12/12 |
| Mild Deficiency | 10–11/12 |
| Moderate | 7–9/12 |
| Significant | < 7/12 |
Color vision deficiency affects L-cone (protanopia), M-cone (deuteranopia), or S-cone (tritanopia) function. Ishihara plates were developed in 1917 and remain the clinical standard. Complete color blindness (achromatopsia) is extremely rare (~1 in 33,000).
What does the Color Blindness Test test measure?
The Color Blindness test uses Ishihara-style pseudoisochromatic plates to screen for color vision deficiencies. Numbers or patterns are embedded in dots of varying hue and saturation. People with red-green deficiency (deuteranopia or protanopia, affecting ~8% of males) cannot distinguish the hidden number. This is a screening tool, not a clinical diagnosis.
How to improve your Color Blindness Test score
- → Take the test with good ambient lighting - dim or colored light skews results.
- → Don't squint or modify your screen colors (no Night Shift / blue light filters).
- → For confirmed deficiency, EnChroma glasses and accessibility tools can improve daily function.
- → Color blindness is X-linked recessive - it affects ~8% of males and ~0.5% of females.
