Brown over blue: In general, the gene for "brown" eye is dominant and the gene for "blue" or :hazel" is recessive. Everyone is born with blue eyes, but in those of us who are genetically destined to have brown eyes, the irides (irises) will turn brown in the first six months or so of life. Those of us who are destined to be "blue"or "hazel-eyed" won't have that iris color change over time. ...Read more

Some eye conditions can lead to poor vision and blue eyes (ocular albinism), but eye color itself is usually not related to eye sight. ...Read more

When i was a baby i had blue eyes, as i grew up they turned green, and now i'm 18 and their slowly turning brown, i want to keep them green, how?

Sorry: The color of the iris is determined by your genetics. The iris is inside the eye and cannot be modified without harm to the vision. If you want different color eyes, the only way is to pick out a colored contact lens to wear over the front of the eye. ...Read more
