Other Causes Eye Color Change. If your eyes check out fine, then the cause of the color change is probably due to age. Aging is the most common cause of a change in eye color, gradually, after reaching adolescence. Most will lighten with age, but hazel (light brown or yellowish brown) or blue can darken.
There are also some unusual eye colors such as red and violet. Brown, green and blue eye color comes from a pigment called melanin. Brown eyes have a lot of melanin in the iris, green eyes have less, and blue eyes have little or no pigment. Two genes, bey2 and gey, work together to make brown, green, or blue eyes. Each gene has two versions or alleles.
