Why do black people have yellow eyes? Yellow eyes among black people are often associated with liver or blood issues. This is not always the case for heavily pigmented individuals. Most black people have yellow eyes because of their melanin pigments that affect the colour of the sclera.
People of colour often have brownish or blotchy eyes due to the accumulation of melanin pigments on their sclera and conjunctiva. For a benign condition such as this, there is no treatment safe enough to use.
Sometimes, blotchy eyes can be confused with a yellowing of the whites of the eyes, which may be a sign of liver disease or vitamin deficiency. But there are more circumstances that lead to yellow eyes in black people.
Let’s explore the notions of why black people have yellow eyes.
Why Do Black People Have Yellow Eyes?
Due to the high concentration of melanin in the sclera, or the white area of the eye, some black people have yellow-tinted eyes.
Melanin is also in charge of the colour of your iris and skin tone. Since the palms and soles of the feet lack significant levels of melanin, the colour is more uniform in all people.
While people of different races may also have yellow eyes, the trait is uncommon. But what causes black folks to have yellow eyes? Is this due to a condition, or does this eye colour have any significance?
Let’s have a look at some of the reasons.
1. A Higher Concentration of Melanin
Black people have a greater amount of melanin, which is the pigment that regulates the colour of the eyes, skin, and even the sclera. The sclera is the white part surrounding the iris. It is a tough, fibrous material that reaches from the cornea: the clear part at the front of the eye, to the optic nerve found behind the eye.
As a result of these increased concentrations of melanin in the sclera, which are simply hereditary and benign, black people may have eye colours ranging in colour from light yellow to brown.
2. Subconjunctival Fat Deposit
Many fair-to-dark-skin people like Filipinos and African Americans have hereditary subconjunctival fat in their bodies, which results in higher levels of carotene. This condition mimics jaundice.
The fat deposits become thicker when the distance from your cornea increases. This causes yellow eyes.
If your body has too much of a chemical called bilirubin, a yellow substance that forms when red blood cells break down.
Normally, it’s not a problem. Your liver filters bilirubin from your blood and uses it to make a fluid called bile. Bile moves through thin tubes (called bile ducts) to get to your digestive tract and then out of your body as waste.
But if you have too much bilirubin in your blood or if your liver couldn’t get rid of it fast enough, it builds up in your body and can turn your eyes yellow. That’s jaundice.
When assessing patients for jaundice, the sclera is the first area to examine. You should be careful when examining individuals for jaundice, as yellow eyes may just be a benign melanin concentration.
If the patient’s bile duct obstructs, they might need to undergo treatment, such as gallbladder removal, to prevent complications. If their liver develops an issue, they might have to undergo a transplant.
4. A reaction to a blood transfusion
In case your hospital mistakenly transfuses the wrong type of blood group, your immune system may fight the wrong blood, releasing bilirubin and causing jaundice. The eyes turn yellow in the process. This problem is rare because of blood testing, but it’s considered an emergency.
Think of bile ducts as drainpipes. They carry the fluid from your liver to your gallbladder (where it’s stored) and then to the small intestine. If gallstones block your bile ducts, bilirubin builds up in your blood. That causes the whites of your eyes to turn yellow.
6. Muddy Sclera-A Normal Eye Variant
The muddy brown sclera is a condition that causes a brownish discolouration in your sclera. Normally, African Americans are affected by this illness.
It is frequently confused with icterus and is essentially a variation of the normal sclera. If you have a muddy sclera, you should see an ophthalmologist see if the outer part of your eye needs to be removed.
Moreover, many people in Africa who live in poverty tend to have issues with their livers, causing a build-up of old red blood cells. This is cirrhosis.
This condition causes scar tissue to replace healthy liver cells. It happens slowly over a long period. Many forms of liver diseases and conditions cause cirrhosis. The most common things that make it more likely are:
- Drinking too much alcohol
- Being obese makes you more likely to get other conditions that lead to cirrhosis.
- Long-term hepatitis B or hepatitis C infection
As more and more scar tissue forms, it’s harder for your liver to work.
8. Excess alcohol and smoking
Drinking heavily for an extended period can cause major liver damage. It can cause inflammation that damages liver cells in certain persons. Scars may eventually replace good liver tissue, making your liver’s task more difficult.
Smoking can turn the whites of the eyes yellow. Tobacco smoke can also have an impact on the tissues around the eyes. It can create puffiness in your eyes.
Tobacco use causes irritation and inflammation, as well as yellow eyes from smoke contact with the lens and other skin conditions that might impact the eyes.
Hepatitis is an inflammation of the liver. A virus that affects liver cells, such as hepatitis A, B, or C, is frequently the cause. The infection can be acute or chronic, and it can be short-term or long-term. This suggests it will last at least 6 months.
Because hepatitis affects the liver, it is unable to filter bilirubin as effectively. This can result in jaundice. Hepatitis can be caused by medicines or autoimmune illnesses in which your immune system attacks your body.
10. Liver infection
Hepatitis viruses are the most prevalent cause of liver infection, however, parasites such as liver flukes can also cause it. They can be contracted by eating raw or undercooked fish or infested plants. Although the illness is uncommon in the United States, ascariasis, or roundworms, can enter and obstruct your bile ducts.
A mosquito bite or contact with contaminated blood transmits the parasite that causes malaria. Blood cells can burst or become damaged, causing them to be filtered out by your liver or spleen. Anaemia and jaundice are caused by the loss of red blood cells.
12. Hemolytic anaemia
Anaemia is a disorder in which your blood does not have enough healthy red blood cells. There are numerous types. Your body destroys red blood cells too quickly in hemolytic anaemia. When this happens, your liver produces more bilirubin than it can handle.
You may have been born with this type of anaemia. It could also be caused by infections or autoimmune illnesses.
Cancer that begins or spreads from the liver is the most common cause of jaundice in cancer patients. It can harm liver cells or bile ducts, impairing bilirubin processing.
Tumours in your pancreas might put pressure on your bile ducts. Bilirubin accumulates when bile cannot drain from your liver into your small intestine. When pancreatic cancer progresses, it frequently affects the liver. This can also result in jaundice.
This uncommon type of cancer normally does not create symptoms until the tumour is large or cancer spreads. When a tumour becomes large enough to block bile ducts, it might cause jaundice.
14. Gilbert syndrome
This uncommon illness affects only 3% to 7% of the population. If you have it, your liver does not produce enough of the enzyme required to process bilirubin. As a result, your blood bilirubin levels rise, and your eyes turn yellow.
How to Get Rid of Yellow Eyes
The best way to get rid of yellowing is to treat the underlying cause as well as any other conditions that may be present.
For example, if a gallstone is obstructing your bile duct, you may require medication or minor surgery. If you have hepatitis, your doctor may prescribe medications to help you fight the virus. When jaundice is caused by alcohol or drug use, a person may require medical support to cease or reduce use.
If a person’s diet is the cause of their jaundice, they should consume more fruits, vegetables, whole grains, beans, legumes, and lean meats.
According to Alderwood Optical, here’s how to eliminate yellow pigmentation in the eyes:
1. Treat the Underlying Health Condition
Bilirubin levels in children and adults should be between 1.0 and 1.2 milligrammes per deciliter (mg/dL). Only when bilirubin levels reach 2-3 mg/dL does yellowing of the eyes or skin develop. Hepatitis, TB, and disorders of the liver, pancreas, or gallbladder can all result in high levels of bilirubin in the blood.
2. Drinking Lemon Juice
Combine lemon juice with water. Stir well and add sugar if desired. This lemon juice can be consumed daily until the yellowing of the eyes has disappeared. One of the greatest methods to recover from jaundice is to stay hydrated. Water aids in the removal of toxins from the liver and kidneys.
3. Eat Healthy Food
Fruits and vegetables high in liver-friendly nutrients, such as limes, grapefruits, papayas, pumpkins, tomatoes, olives, and ginger, can help you recover from jaundice. In addition, your eye doctor may advise you to consume lean protein sources such as tofu, lentils, and fish instead of red meat.
4. Avoid Food Rich in Saturated and Trans Fat
Avoid foods with high levels of saturated and trans fat in your diet. Dairy items such as cheese, whole milk, and full-fat yoghurts should also be avoided.

Frequently Asked Questions (FAQs)
Can melanin cause yellow eyes?
Jaundice occurs when the liver, pancreas, or gallbladder are not functioning properly. Speak to your healthcare provider if you notice your sclera turning yellow. Typically, for African Americans, due to high levels of a dark brown pigment called melanin, the sclera may have brownish spots, which is harmless.
Why do some people have yellow eyes naturally?
There are many possible causes of yellow eyes. Most are related to problems with the gallbladder, liver, or pancreas, which cause excess amounts of a substance called bilirubin to collect in the blood. Diagnosing and treating any underlying medical conditions is the first step toward getting rid of your yellow eyes.
What do yellow eyes signify?
Yellow eyes occur when the whites of the eye (sclera) turn yellow (called scleral icterus). It is a sign of jaundice, which is a symptom of an underlying condition, often of the liver. Your eyes turn yellow when there’s a buildup of bilirubin.
What is the rarest eye colour?
Green is the rarest. It shows up in about 9% of Americans but only 2% of the world’s population. Hazel/amber is the next rarest of these. Blue is the second most common and brown tops the list with 45% of the U.S. population and possibly almost 80% worldwide.
What are yellow eyes called?
Jaundice refers to a yellowing of the whites of the eyes or the skin. It is often the result of a medical condition that causes a yellow-pigmented compound called bilirubin to build up in the blood.
It’s your turn…
Black people have yellow eyes due to several reasons. While some may assume it is due to health issues, it’s mostly a result of too much melanin.
Melanin affects the colour of the sclera and is usually benign. However, you may need to go to the hospital for a medical examination to determine the cause and appropriate treatment for your yellow eyes.
