What causes yellowing of the eyes?

Yellowing of the eyes may be caused by factors such as aging, environmental irritation, pinguecula, hemolytic anemia, hepatitis, and others. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a qualified physician. Specific analyses are as follows:

1. Aging

With advancing age, lipids in the body may gradually deposit, leading to a slight yellow appearance of the eyeball. This is a normal physiological aging process and does not significantly impair visual function.

2. Environmental Irritation

Prolonged exposure to wind, sun, and ultraviolet (UV) radiation may accelerate lipid oxidation on the eye surface, causing it to appear yellow. It is advisable to wear sun hats and sunglasses when outdoors, which helps reduce UV damage to the eyes.

3. Pinguecula

Pinguecula is an eye condition that may be related to long-term exposure to sunlight and UV radiation. It mainly presents as a pale yellow elevated patch between the white and black parts of the eye, and may also be accompanied by symptoms such as increased eye discharge and blurred vision. Patients are advised to use medications such as tobramycin dexamethasone ophthalmic solution, sodium hyaluronate ophthalmic solution, or dexamethasone sodium phosphate ophthalmic solution as directed by their doctor.

4. Hemolytic Anemia

This condition may be associated with abnormal globin proteins or exposure to toxic substances. The disease leads to widespread destruction of red blood cells, allowing bilirubin to enter the bloodstream and resulting in yellowing of the eyes, possibly accompanied by dizziness. Patients should follow medical advice and take medications such as vitamin B12 tablets, methylprednisolone tablets, or cyclophosphamide tablets as prescribed.

5. Hepatitis

Hepatitis may be linked to factors such as heavy alcohol consumption or viral infections. The disease can disrupt bilirubin metabolism, leading to yellowing of the eyes, along with symptoms like fatigue and reduced appetite. Patients should take medications such as bicyclol tablets, recombinant human interferon α2b injection, or Anluohuaxian pills under medical supervision to improve their condition.

In daily life, patients are advised to maintain a balanced diet with proper combination of meat and vegetables, and consume foods such as cabbage, lean pork, and apples in moderation. Engaging in mild physical activities like walking or yoga may also benefit recovery.
