  All right, you are very interested in the question aren't you? Anyway, typically speaking, our eye color would not change throughout my lifespan, but sometimes, diseases would let it happen, let's take glaucoma and cataract for examples, they would turn your eyes green and white respectively, leading to a lot of problems and great damages to your eyes. Thus, it could be seen as a health warning. Just be careful.

  Eye color is decided by gene, that is, when you were born, your eye color has already come into being. But with time flies eye color will change gradually with living environment and habits and customs, such as eating habits, smoking and liver diseases. Also, aging is also one factor that leads to eye color changing. Eye color will become lighter and lighter when we are in 50s-60s.
