People with brown eyes have melanin on the back layer of the iris and some on the front layer, which absorbs more light and causes the iris to look brown. Eyes with no melanin on the front layer of the iris scatter light so that more blue light reflects out, so that the eyes appear blue.
Where do brown eyes come from?
Brown is the most common eye color. Dark brown eyes are most common in Africa, East Asia, and Southeast Asia. Light brown eyes are found in West Asia, the Americas, and Europe.
Can parents with blue eyes have a brown eyed child?
Every time. This has to do with the fact that blue eyes are supposed to be recessive to brown eyes. This means that if a parent has a brown eye gene, then that parent will have brown eyes. Which makes it impossible for two blue-eyed parents to have a brown-eyed child -- they don't have a brown eye gene to pass on!
