Can a person's eye color change with mood or age?

Eye color is determined by the amount and type of pigments in the iris, which is the part of the eye that gives it color. The color of the iris is determined by genetics and is usually fixed from birth. However, some people may experience slight changes in their eye color over time due to various factors, but changes in eye color due to mood are a myth.

As we age, it is possible for our eye color to change. Most commonly, people experience a darkening of their eye color as they age, but some people may also experience a lightening of their eye color. This is due to changes in the amount of melanin in the iris. Melanin is a pigment that is responsible for the color of our hair, skin, and eyes. As we age, the amount of melanin in our body decreases, which can cause our eye color to change.

However, changes in eye color due to mood are not possible. While some people may feel that their eye color changes depending on their mood, this is simply a perception and not a physical reality. The color of the iris is determined by the amount and type of pigments present, and this does not change based on a person's emotional state.
