Eye discomfort is not related to the liver. Eye discomfort is usually seen in dry eye syndrome, also known as corneoconjunctival dryness. Dry eye is an eye disorder caused by a variety of factors, with dry eyes as the main symptom. It is often accompanied by itching, foreign body sensation, burning sensation in both eyes, or uncomfortable eye manifestations such as photophobia, blurred vision, and fluctuating visual acuity. In addition, the causes of dry eye usually include inadequate tear secretion from the lacrimal gland, poor lid gland function due to eyelid disease, vitamin A deficiency, chronic conjunctivitis, chemical burns, and eyelid disease that causes poor lid closure, decreased blinking, and prolonged stays in cool rooms or hot, windy outdoor environments. Therefore, when patients experience eye discomfort, they must go to the hospital’s ophthalmology department for symptomatic treatment. They should usually consume more vitamin A-rich foods, such as milk, eggs, and vegetables containing carotenoids, and take cod liver oil orally to maintain eye health and relieve eye discomfort.
