This is known as heterochromia - and is caused by differing amounts of a pigment called melanin. This can have a genetic cause or be the result of disease or illness.
When the irises are two different colours, this is complete heterochromia.

∙ 14y agoWhile it is not common to have one eye blue and the other brown, it does happen. It usually does not hurt anything. Since it is different from normal, an eye doctor should examine the eye to check for abnormalities, but other than that, it should not cause any problems. If it is a child and the child is extremely upset from teasing by other children, it may be possible to make both eyes the same color by using contact lenses.

∙ 12y agoIt is all based on alleles, the dominant allele is Brown and the recessive is blue,grey or green. If both parents have brown eyes the chances are that there child will have brown eyes as you need two recessive alleles to get blue eyes whereas you only need one dominant allele to get brown eyes. But say for example both your parents have Brown eyes though they both have 1 parent with blue eyes, if they both carried that recessive allele and both recessive alleles from both parents joined the child would have blue eyes.
Eyes are all based on genetics and DNA.

Why Several genes control human eye color. Because of this eye color shows a continuous variation from very dark brown to green to blue. What is this an example of?
Eye color is not an example of polygenetic traits. Skin color is. Eye color is rather simple as far as genetics go (in humans). Brown (B) is dominate and blue (b) is recessive. A person with blue eyes has to have to have both genes for the color blue (bb). A person with brown eye color can has both genes for brown (BB) or one for brown and one for blue (Bb). The blue is not expressed in this case with Bb. Some people have hazel eyes but this is a variation of the blue color.
