Colour Vision Changes across Lifespan: Insights from FM100 and CAD Tests

Area of Science:

• Ophthalmology
• Vision Science

Background:

• Investigated color vision changes across a wide age range (19-70 years).
• Included participants with and without red-green color vision disorders.

Purpose of the Study:

• To evaluate the impact of aging on color vision.
• To assess the diagnostic accuracy of different color vision tests.

Main Methods:

• Utilized anomaloscope, HRR, FM100 hue, and CAD tests for color vision assessment.
• Analyzed chromatic sensitivity of red-green and blue-yellow opponent channels.
• Examined age-related changes in color vision test performance.

Main Results:

• No age-related correlation found for red-green channel sensitivity.
• Confirmed decreased blue-yellow channel sensitivity with age using FM100 and CAD tests.
• FM100 hue test demonstrated 81.25% sensitivity and 95.38% specificity for moderate to severe deficits; CAD test showed 100% sensitivity and specificity but misclassified some deutan deficits.

Conclusions:

• The FM100 hue test is effective for identifying moderate to severe red-green color vision deficiencies.
• Mild color vision deficiencies may not be detected by the FM100 hue test.
• Aging affects blue-yellow color perception more than red-green perception.
