Why are a baby's eyes normally blue at birth?!
Question:
Answers:
Why? Melanin, the brown pigment molecule that colors your skin, hair, and eyes, hasn't been deposited in the irises of your eyes. The iris is the colored part of the eye that controls the amount of light that is allowed to enter. Some other animals are born with blue eyes, too, such as kittens.
Melanin is a protein. Like other proteins, the amount and type you get is coded in your genes. Irises containing a large amount of melanin appear black or brown. Less melanin produces green, gray, or light brown eyes. If your eyes contain very small amounts of melanin, they will appear blue or light gray. People with albinism have no melanin in their irises and their eyes may appear pink because the blood vessels in the back of their eyes reflect light.
Melanin production generally increases during the first year of a baby's life, leading to a deepening of eye color. The color is often stable by about 6 months of age. However, several factors can affect eye color, including use of certain medications and environmental factors. Some people experience changes in eye color over the course of their lives. People can have eyes of two colors. Even the genetics of eye color inheritance isn't as cut-and-dried as was once thought, as blue-eyed parents have been known (rarely) to have a brown-eyed child!

Depends on heridity. I have never seen a baby with blue eyes at birth in India. It is a common feature in the west.
theyre eyes dont usually develope when they are born, when they get older their eyes turn brown. the color blue isnt really an eye color, its just when your eye is missing something. thats all i know, i need to pay more attention in science :]
