I have no doubts that the eye colors of infants can change during the first several months of life. I've got my own proof in my sibling's (and my own) baby pictures. But what about years later, like adolescence or even adulthood? I know people who say their eye colors change depending on mood, I know people who say their eye colors change during different times of the year, I know people who swear that they can change the color of their eyes at will. Sometimes when I look into a person's eyes I see regularly, I swear they look different sometimes. Are my eyes deceiving me? I'm of the opinion that the clothes a person is wearing, the lighting of the environment, and the colors of the surrounding environenment have an effect on what we see when we focus on something. I may be wrong, but it's a speculation of mine. Also: Can certain drugs effect the color of the eyes? What's your opinion?
