Color perception naturally changes as we age, primarily due to physical changes in our eyes. These changes include:
- Yellowing of the lens, which affects how we perceive blues and purples
- Decreased pupil size, reducing the amount of light entering the eye
- Fewer cone cells functioning efficiently
- Reduced sensitivity to contrast
By age 60, most people need three times more light to see as well as they did at age 20. Color discrimination also becomes more difficult, particularly in the blue-green spectrum. However, these changes are gradual and can be partially compensated for with proper lighting and regular eye check-ups. Some age-related color perception changes can also signal more serious conditions, so it’s important to monitor any sudden changes.
