Green eye color is the rarest color found around the world, estimated at only 2%. About 5% to 8% of the world's population has hazel-colored eyes. Hazel eyes have a higher concentration of melanin around the eye's border, which can result in a multi-colored appearance that varies between copper and green. Brown eyes are the most common eye color in the world with over 55% of the world's population having brown eyes. Listed below are some interesting facts about eye color: Brown eyes have the most melanin, green eyes less, and blue eyes have none. A green iris, for example, has blue and some yellow while a brown iris contains mostly brown. More melanin means darker eyes and less melanin means lighter eyes. Because of the tiny elevations and depressions in the iris, false negatives are about 10 times less common in iris scanning than in facial recognition.Įven identical twins, with the same DNA, do not have the same iris characteristics or the same fingerprints! Eye ColorsĮye color is determined by the amount of melanin, or pigment, in the iris tissue. The iris identification error rate is about one in a million – even less when you correlate it with other biometric scanning like fingerprinting or facial recognition. The iris contains approximately 250 different characteristics that determine a person's identity, which is five times more than a fingerprint! It is undeniable that our fingerprints are one-of-a-kind, but the uniqueness of the iris is far greater in comparison. However, it wasn’t until much later that a system to recognize and catalog these identification points was developed. IrisĪs early as the 1950s, scientists and health professionals suggested that the characteristics of the iris could be used for identification purposes. In ancient times, a prediction of an individual’s destiny was based on the unique characteristics of their iris. The color of the iris varies from person to person and is one of the traits that are responsible for giving us our individual appearance. It works much like a camera’s aperture, regulating light levels and helping us focus. It is a thin, circular piece of tissue, responsible for controlling the diameter and size of the pupil. The iris is the part of the eye that produces color, and is the first thing most people draw to. By simply looking at them, eyes can convey a warm, bright, and inviting vibe as well as a cold and repellent one – they are the window to a person’s soul.
