Hello, I'm an expert in the field of pediatric ophthalmology. Let's dive into your question regarding the possibility of a baby's eyes changing color from brown to blue.

Answer in English:

Yes, it is possible for a baby's eyes to change color, typically from a blue or gray color to brown, as they grow older. This color change is due to the maturation of the iris, which contains pigments that determine eye color. During infancy, the iris is not fully developed, and the collagen fibers within it are less tightly packed, which can make the eyes appear lighter in color. As the child grows, these fibers become more condensed, and the true pigmentation of the iris becomes more apparent. However, it is important to note that the reverse—eyes changing from brown to blue—is extremely rare and not well-documented in medical literature. The pigmentation process is largely determined by genetics, and once the iris has fully developed and the pigmentation has set, it typically does not change back.
