Understanding Your Color Blind Test Results

Learn what your Ishihara test score means, how to interpret the results, and what steps to take next. Our guide helps you understand your color vision status.

Interpreting Your Score

The standard Ishihara test consists of 12-38 plates. Our online screening uses 12 plates to assess your red-green color vision. Here's what your score indicates:

✓ Normal Color Vision (10-12 Correct)

Scoring 10 or more plates correctly suggests normal red-green color vision. You can distinguish the colored numbers from the background dots as expected.

What this means: Your cone cells appear to be functioning normally for red-green color perception. However, this online test does not screen for blue-yellow color deficiencies.

⚠ Possible Mild Deficiency (7-9 Correct)

Scoring 7-9 plates correctly may indicate a mild color vision deficiency, such as deuteranomaly or protanomaly. These are the most common forms of color blindness.

What this means: You may have some difficulty distinguishing certain shades of red, orange, yellow, and green. However, factors like monitor calibration and lighting could affect results.

Recommendation: Consider scheduling an appointment with an eye care professional for comprehensive testing under controlled conditions.

⚠ Likely Color Vision Deficiency (0-6 Correct)

Scoring 6 or fewer plates correctly strongly suggests a red-green color vision deficiency. This could be protanopia, deuteranopia, or their milder forms.

What this means: You likely have difficulty distinguishing between certain colors, particularly in the red-green spectrum. This affects approximately 8% of males and 0.5% of females.

Recommendation: We strongly recommend consulting an eye care professional for a definitive diagnosis and to determine the specific type and severity of your color vision deficiency.
