For instance, if you have blue eyes, they may seem to take on a darker shade if you’re wearing a dark blue shirt. You may have noticed that eye color can be affected by what you are wearing. However, certain medical conditions, medications, and health conditions can create changes in eye color. Can Eye Color Change Overtime?Įye colors generally stay the same for an entire lifetime. Heterochromia is more commonly seen in dogs, such as Australian sheepdogs, Dalmatians, and Huskies, as well as in cats and horses. One condition that can lead to eyes being different colors is Horner’s syndrome. However, it may result from a medical disease or injury. Typically, different eye colors are the result of a harmless change in genes. It may also be due to a medical condition such as glaucoma or an injury such as bleeding in the eye. ![]() This may be a hereditary condition, so it may be present in multiple members of the same family. Heterochromia means different colored eyes in the same individual. Green, blue, gray, and hazel eye colors are most commonly found among people of European ancestry. According to the American Academy of Ophthalmology, only 9 percent of people in the U.S. Green is the least common eye color worldwide. Extra collagen in the eye blocks a blue color from appearing, creating a grayish hue. This color is often compared to the color of the eyes of a cat.Īccording to the World Atlas, 3 percent of people in the world have gray eyes. Like blue, gray is the color that appears when the front layer of the iris has little or no melanin. It is a light brown shade.Īccording to the World Atlas, about 5 percent of the world’s population has this unique color. Amber EyesĪmber is often compared to the color of copper or gold. People with hazel eyes may have flecks or spots of these colors as well.Īccording to the American Academy of Ophthalmology, about 18 percent of people in the U.S. Hazel is a combination of the colors brown and green. People with blue eyes may be more sensitive to light. The blue color is not the result of a blue pigment, but rather the way light reflects off the surroundings. In the United States, about 25 percent of people have blue eyes.ĭue to the lack of pigment, the eye absorbs less light. Blue Eyesīlue is the eye color of people who have little or no pigment in the front part of the iris. However, people with brown eyes have a higher risk of cataracts. People with brown eyes are less likely to develop certain eye conditions, including macular degeneration, eye cancer, or diabetes-related retinopathy. Brown Eyesīrown is the most common eye color in the world. While eyes can be varying shades of each, the basic eye colors include brown, blue, hazel, amber, gray, and green. ![]() The Basic Colors: Brown, Blue, Hazel, Amber, Gray & Green No one else has the exact same eye color that you do. Most people have brown pigment at the back layer of the iris, even individuals with green or blue eyes.Įye color is often compared to a specific personal marker, like a fingerprint, that is uniquely yours. How Do Eyes Get Their Color?Įye color is formed by the amount of pigment in the front layer of the iris. Gene variations and interactions in different genes can cause someone to have different colored eyes than their parents or even than any other family members. Several genes are responsible for the amount of pigment in the eyes, making it possible for two blue-eyed parents to have brown-eyed children. People with blue eyes have much less melanin. It is possible, so it turns out that this old model was too simplistic.Įye color is directly connected with the amount and quality of pigment, also known as melanin. ![]() ![]() In the past, many people thought that if both parents had blue eyes, they couldn’t have a brown-eyed baby. However, today, studies confirm that the eye color inheritance pattern is more complex. Traditionally, people believed that eye color was determined by a single gene. Typically, the eyes stay the same color throughout life, but they may change color due to health conditions, medications, or injury. Blue eyes have little or no pigment, while brown eyes have a large amount. The color of your eyes is determined by the amount of pigment, known as melatonin, in your iris. The pupil is the small opening that appears black in the middle of your eye. The iris is that colored part of the eye, surrounding the center or pupil.
