The color of our eyes depends on the amount of pigment in the iris. The majority of humans have brown eyes while a smaller percentage of people have blue and gray and many other variations between blue and brown. Green is the rarest eye color.

These days, it's possible to change one's eye color with contact lenses that come in every color of the rainbow. Want to change your brown eyes to blue? You might want to think twice - blue eyes are more susceptible to age-related eye diseases like macular degeneration than those with darker eyes.

In this section we look at the different eye colors, answer commonly asked questions, and also discuss conditions and genetic traits that affect eye color.
