Why Do My Eyes Change Color?
What Causes Color Variation?
Your eyes can change color or become more intense over time. This is due to a combination of factors such as genetics, age, and environment. The most common cause of eye color change is genetics. As you age, the pigment in your eyes can change. This happens because the melanin level decreases as you get older. This can result in a change of color or an intensification of your existing eye color.
Eye Color and Genetics
Eye color is determined by the amount of melanin in the iris of the eye. The amount of melanin determines the eye color. People with lighter eyes have less melanin, while those with darker eyes have more. The genetics of eye color are complex and not fully understood. It is believed that up to 16 genes can influence eye color.
Environmental Factors that Can Cause Eye Color Change
Environmental factors can also play a role in eye color change. Exposure to ultraviolet radiation from the sun can cause an increase in melanin production, resulting in darker eyes. Changes in the environment, such as a move to a new location, can also cause a change in eye color. This is because different climates can have different levels of melanin production.
Is Eye Color Change Permanent?
In most cases, the change in eye color is not permanent. The change is often caused by a temporary increase in melanin production due to environmental conditions. Once the environmental conditions change, the eye color will usually return to its original color. However, for some people, the change in eye color can be permanent.
Conclusion
Eye color is determined by the amount of melanin in the iris of the eye. Genetics plays a role in determining eye color, and environmental factors can cause eye color change. In most cases, the change in eye color is not permanent, but some people may experience a permanent change. If you are concerned about your eye color, it is best to consult an ophthalmologist.
