Why do eyes darken when angry?
Can your eyes change color? – Contrary to popular opinion, your eyes do not change color based on your emotions. The iris is a muscle that expands and contracts to control the size of your pupil. It gets bigger in dim lighting and gets smaller in bright lighting.
- It also shrinks when you are focusing on close tasks, such as reading a book.
- Certain emotions can also change the pupil size, such as anger, grief or happiness.
- This can cause the pigments in the iris compress or spread apart, slightly changing the appearance of your eye color.
- Also because the pupil is black, your eyes appear darker.
There are times when your eye color might darken slightly, such as puberty, pregnancy, and aging for 10%-15% of Caucasians with light-colored eyes.

THE CLAIM – Eye color can change as we age. THE FACTS – It can bend light, bring the world into focus, and next to the human brain may be our most complicated organ. But for many people the most intriguing feature of the human eye is simply its color. Can it really change for no apparent reason? In most people, the answer is no.
Eye color fully matures in infancy and remains the same for life. But in a small percentage of adults, eye color can naturally become either noticeably darker or lighter with age. What determines eye color is the pigment melanin. Eyes that have a lot of it in the connective tissue at the front of the iris, called the stroma, are darker, while those that have less tend to be lighter.
The levels of melanin generally remain the same throughout life, but a few things can change them permanently. The first is a handful of ocular diseases like pigmentary glaucoma. Another is a condition called heterochromia, or multicolored eyes, which affects about 1 percent of the population and is often caused by traumatic injuries.
An example of this can be seen in the rock star David Bowie, who attributes his contrasting eye colors, hazel and light blue, to a blow to the face as a child. The third cause appears to be genetics. A study in 1997, for example, looked at thousands of twins and found that 10 percent to 15 percent of the subjects had gradual changes in eye color throughout adolescence and adulthood, which occurred at nearly identical rates in identical twins.
THE BOTTOM LINE – Eyes can change color in some people because of genetics or injury. ANAHAD O’CONNOR Really? [email protected] : The Claim: Eye Color Can Change as We Age (Published 2005)
