I’ve been experiencing persistent eye discomfort recently. When I looked in the mirror, I noticed that the whites of my eyes (sclera) appeared slightly yellowish and had visible blood vessels. What causes slight yellowing and bloodshot appearance of the sclera?

Mild yellowing of the sclera accompanied by visible blood vessels may result from excessive fatigue and deficiency of the liver and spleen, conjunctivitis, or prolonged wear of contact lenses. In daily life, ensure adequate eye rest, avoid staying up late, and limit extended use of electronic devices such as smartphones and computers. Maintain a nutritionally balanced diet. If additional symptoms arise, consult a qualified physician at an accredited hospital promptly.
