Cloudy eyes are usually caused by conjunctival hyperplasia and hyperpigmentation, liver function abnormalities, chronic conjunctivitis and so on. 1. Conjunctival hyperplasia and hyperpigmentation: If you are exposed to strong ultraviolet rays or sandy environments for a long period of time, it may lead to conjunctival hyperplasia and hyperpigmentation, which can lead to cloudy and yellowish eyes. 2. Liver function abnormality: cloudy, yellowish eyes may be caused by abnormal liver function resulting in increased bilirubin levels, such as hepatitis, fatty liver, and so on. 3. Chronic conjunctivitis: Chronic conjunctivitis can easily lead to prolonged conjunctival stimulation, resulting in dilated capillaries in the conjunctival tissue, lipid metabolism abnormalities, which can lead to cloudy, unclear and yellow eyes. It is recommended that patients consult a regular hospital, complete the relevant examination, clarify the cause of the disease, and follow the doctor’s instructions for treatment.
