Eye color is determined by the amount and type of pigments in the front part of the iris, as well as by the way the iris scatters light.
While some people are born with a specific eye color, others may experience changes in eye color throughout their lives. In this article, we will explore the factors that can cause changes in eye color and what it means.
Melanin and Eye Color
Eye color is mainly determined by the amount and type of melanin, the pigment that gives color to our skin, hair, and eyes. The more melanin in the iris, the darker the eye color. Melanin can be found in two forms: eumelanin, which gives a brown-to-black color, and pheomelanin, which gives a yellow-to-red color. The amount of melanin in the iris is determined by genetics, but other factors can also play a role.
How Eye Color Changes with Age
As we age, the amount of melanin in the iris can change. In some people, the iris may become thinner, allowing more light to scatter and giving the eyes a lighter appearance. This can happen gradually over time, and the change may be barely noticeable. However, some people may experience a noticeable change in eye color, particularly if their eyes were very dark, to begin with.
Additionally, some people may find that their eyes appear to change color due to certain medical conditions or medications, like inflammation of the iris or certain types of eye drops, which can cause discoloration.
What Does It Mean?
A change in eye color is not always a cause for concern. In most cases, it is simply a normal part of aging or a result of changes in the amount of melanin in the iris. However, if you experience a sudden or dramatic change in eye color, it is important to consult with an eye doctor, as this could be a sign of a more serious underlying condition.
Conclusion
Eye color is determined by the amount and type of pigments in the front part of the iris, as well as by the way the iris scatters light. While some people are born with a specific eye color, others may experience changes in eye color throughout their lives. This change can be due to many factors, including age, medical condition, or medications. It is important to consult with an eye doctor if you experience a sudden or dramatic change in eye color.
