A person with differently colored eyes or eyes that are more than one color has heterochromia. about the symptoms, types, risk factors, causes, diagnosis, and treatment. Learn how eye color is formed, how genetics and melanin work, and how to use a medical eye color chart.
Includes rare colors, babies and heterochromia. Heterochromia describes when a person's eyes aren't the same color. Find out about the different types of heterochromia and what causes it to occur.
For example, a brown eye might have one section that's blue. Or, a brown eye might have spikes of blue that radiate out from the center (pupil). Many people with heterochromia don't have underlying health issues, and their differently colored eyes are a harmless and unique trait.
However, some medical conditions can cause heterochromia. Heterochromia of the eye is called heterochromia iridum (heterochromia between the two eyes) or heterochromia iridis (heterochromia within one eye). It can be complete, sectoral, or central.
In complete heterochromia, one iris is a different color from the other. In sectoral heterochromia, part of one iris is a different color from its remainder. In central heterochromia, there is a ring.
What Determines Eye Color? Your eye color is shaped by a mix of genetics, pigment, and how light scatters inside your eyes. Most of it comes down to melanin, a pigment that gives the iris its color. People with more melanin usually have brown eyes.
Those with less melanin may have blue, green, or hazel eyes. Hazel eyes often appear to shift in color because they combine several pigment layers. The blue/brown mix eye has been linked by Iridologists with a disposition to biliary or hepatic (liver) troubles.
It is believed that the colorations on top of the blue eye are a sign of toxicity in the body due to digestive problems. The combination of pigments and how widely they're spread and absorbed by the stroma determines whether an eye looks brown, hazel, green, gray, blue, or a variation of those colors. 3 For example, brown eyes have a higher amount of melanin than green or hazel eyes.
Blue eyes have very little pigment. Mixed Blue eyes are blue eyes with noticeably prominent brown central heterochromia around the pupil. The predominant outer color is the true color of the iris however which in this case is blue.
These multicoloured eyes are two toned with strong contrast and can under certain lighting and from. Heterochromia, specifically one blue and one brown eye, is a variation in iris coloration often a harmless genetic trait, but if acquired later in life, it can signal an underlying medical condition requiring ophthalmological evaluation.
