Do certain foods or diets cause eye color to change?

Do certain foods or diets cause eye color to change? The short answer is no; eye color is determined by genetics and typically remains constant throughout a person’s life. However, certain factors, like lighting and emotions, can temporarily alter the appearance of eye color. While diet and nutrition can significantly impact eye health, they do not change the pigment of the iris.

Can Diet Impact Eye Color Permanently?

Understanding Eye Color and Genetics

Eye color is primarily determined by the amount and distribution of melanin in the iris. Genetics play a crucial role, with multiple genes contributing to the final color. The most significant genes are OCA2 and HERC2, which influence melanin production. Since eye color is genetically encoded, it remains stable over a person’s lifetime.

What Can Temporarily Change Eye Color?

While diet cannot change eye color permanently, certain factors can cause temporary changes in appearance:

• Lighting: Different lighting conditions can make eyes appear lighter or darker.
• Clothing and Makeup: Colors worn near the face can reflect in the eyes, altering their perceived color.
• Emotions: Pupil dilation from emotions like excitement or anger can affect how eye color is perceived.
