The colored part of the eye is called the iris. The iris has pigmentation that determines the eye color. Irises are classified as being one of six colors: amber, blue, brown, gray, green, hazel, or red. Often confused with hazel eyes, amber eyes tend to be a solid golden or copper color without flecks of blue or green typical of hazel eyes.

Eye color refers to the color of your iris. The iris is the colored part of the eye that surrounds the pupil. Your pupil is the small black opening in the center. The iris has two layers. Eye color results from the amount of pigment (melanin) you have in the front layer (stroma). Almost everyone (even people with blue or green eyes) has brown pigme...
Eye colors vary based on how much melanin your body makes. Melanin is a naturally occurring pigment that gives color to skin, hair and eyes. Skin cells called melanocytes are responsible for making melanin. Everyone’s melanocytes produce different amounts of pigment. People whose skin cells don’t make much melanin have lighter eyes. People whose sk...
Scientists used to think only one gene determined eye color. They thought that a simple inheritance pattern caused someone to have more or less melanin. For example, they thought two blue-eyed parents wouldn’t be able to have a child with brown eyes. Today, scientists know that the inheritance pattern is more complex. Many genes work together to de...
About 10,000 years ago, everyone in the world had brown eyes. Scientists believe that the first blue-eyed person had a genetic mutation that caused the body to produce less melanin. Today, about half of the people in the United States have brown eyes. Eye colors range from very light blueto dark brown. Some eyes also have flecks or spots of darker ...
People with blue eyes don’t actually have blue-colored pigment. The iris only looks blue because of the way light reflects. An eye with less melanin absorbs less light. Collagen fibers in the eye scatter the light, and it reflects off of the surroundings, making eyes appear blue. People with lighter eyes may be more sensitive to light because they ...
Many babies are born with blue or brown eyes. But newborns can have any eye color. As a baby grows, melanin continues to develop. If a blue-eyed newborn develops more melanin in their irises, their eyes might darken or turn brown or hazel. This change usually happens in the baby’s first year. But it can take up to a few years for eyes to turn the c...
Eye colors usually stay the same throughout a person’s lifetime. Certain health conditions and disorders can cause changes in eye color. Your eye color might appear to change a bit from time to time. For example, your eyes might look like they’re a darker shade of blue if you’re wearing a blue shirt. The change in colors happens when light reflects...
A condition called heterochromia causes the iris to be different colors. People with this condition may have different colors within one eye (for example, the iris may be half one color and half another). Or they may have a different color in each eye. Most often, heterochromia results from a harmless gene change. It usually happens sporadically, w...
Several conditions can affect eye color. These include: 1. Albinism: People who have an inherited condition called albinismhave little or no melanin in their eyes, hair and skin. People with albinism usually have eyes that are very light blue. Rarely, they have pink or red eyes. Without melanin, their irises are clear, which makes blood vessels ins...
A type of medication called prostaglandins can cause the iris to change color. Providers use prostaglandins to treat glaucoma. Prostaglandin is also the main ingredient in a serum called Latisse® that lengthens eyelashes. These medications can cause the eyes to become darker.

Mar 3, 2021 · Differences in eye color are also influenced by differing amounts of melanin, the pigment responsible for eye color (plus hair color and skin tone). For instance, many white non-Hispanic babies are born with blue eyes because they don’t have the full amount of melanin present in their irises at birth.
- Why Your Eyes Are the Color They Are. Eye colors can range from pale blue to dark brown that looks black. The color of your eyes is determined by a combination of pigments in the iris, a two-layer structure that contains clusters of three main pigments: melanin, pheomelanin, and eumelanin.
- Eye Color Percentages. Brown is the most common eye color in both the United States and the world. More than half of all people have brown eyes. Green eyes are considered to be the rarest—only 2% of all people have them.
- Genetics of Eye Color. Multiple genes help determine your eye color. Research shows that you cannot predict a baby's eye color based only on the parents' eye colors because many genes are involved.
- Why Brown Is Most Common. Researchers believe that brown eyes are the most common because our first human ancestors had this eye color. High levels of melanin help to protect the eyes from damaging sun rays.
May 23, 2023 · Black, Hispanic, and Asian babies commonly have brown or black eyes. If your baby has blue eyes, they may not stay that way. As a newborn, the pigment is not widely spread throughout the iris. During the first six months of life, more of the pigments are produced. By age 1, you usually have your permanent eye color.
Aug 30, 2023 · The actual pigment that gives the eye color is called melanin, which darkens your eye color. The gene groupings that cause your eye to have more melanin are the most common, which is why brown is the most common eye color. Brown was also the first eye color in human beings, with the rest coming later as genetic mutations. The Most Common Eye Colors
Mar 4, 2019 · It appears this is caused by more melanin developing in the iris during infancy and early childhood. So, a child born with light blue eyes may end up with a darker blue eye color or an entirely different eye color. Most individuals achieve stable eye color by 6 years of age. However, a subpopulation of 10% to 15% of Caucasians can have changes ...
