The exact color of the human eye is determined by the amount of a single pigment called melanin that is present in the iris of the eye. Melanin is a dark brown pigment that is deposited on the front surface of the iris. If a lot of melanin is present, the eye will appear brown or even black. If very little melanin is present the iris appears blue. Intermediate amounts of melanin produces gray, green, hazel or varying shades of brown.
Genes work by directing the production of enzymes, chemicals that control all of the processes that occur in our body. Eye color genes, through the enzymes they produce, direct the amount and placement of melanin in the iris. ===> In general Caucasian babies are born with blue eyes because at the time of birth they haven't begun to produce melanin in their irises. Their eyes may change to green, brown or other colors as melanin production begins. Babies of other ethnic origins such as African, Asian, Hispanic and Native American, are often born with brown or black eyes. Albinos have no pigment in their irises so the blood vessels in the back of the eye reflect light making the eyes look pink. <==== Albinos also lack melanin in their skin and hair. Since albinism is caused by a recessive allele, two normal parents may produce an albino. An albino can have normal offspring if the other parent is normal for melanin production.

I don't know about black or other nationalities but yes all white babies are born with blue eyes. They will start to change in the first year of life if they are meant to be a different color.

It's all in Genes and i don't mean blue jeans lol ! I have only seen black children with brown never blue and as far as for children with blue eyes there are those born with green too and if most of the time they haven't changed by the time they are around 2-3 yrs of age they usually stay the color of green, blue.

Only babies that actually have blue eyes are born with blue eyes. There are actually only two different eye colors-blue and brown, but there can be different amounts of those two colors depending on the genetics which can blend to make different colors (green, hazel, etc). However, I do think that alot of babies are born with hazel eyes...

Not all babies are born with blue eyes. For instance, I was, but my siblings were both born with brown eyes. It normally changes around six months of age.

Maybe all caucasian babies have blue eyes at birth but my children were born with black eyes that turned light brown after a week or so. They are biracial, black/white.

babies are born with blue, black or brown eyes
over a period of 12 - 52 weeks gradually their true colour emerges - usually first as small pigments in the base colour and then gradually into adult colour
for example green eyes start as blue then gradually green or hazel flecks appear and gradually become more dominant until the eyes are truly green
some childrens eyes dont completely change until they are 5-6 years old!

Non of that is true, I've had 4 kids two have hazel eyes and two brown. The two with hazel eyes did have sort of blue eyes when they were born but the other two always had brown eyes...
My eyes were brown until I was 15 and they started to change, now they are hazel. (but more green than brown)

What you say is true.....all babies ARE born with blue eyes...you cannot usually tell what color eyes they will have until 6 months of age. Brown is usually dominant over all other colors.
