Xerophthalmia is a phenomenon of conjunctival dryness mainly due to the lesions of conjunctival tissue itself. It is a chronic disease that requires long-term treatment. You must avoid medications that reduce tear production, such as blood pressure medications and antidepressants.
Treatment of xerophthalmia is to improve the nutritional status of patients and prevent secondary infection. You should eat foods rich in vitamin A, such as milk, eggs and vegetables with carotene, while taking fish liver oil orally. Medicine shouldn’t be your best choice.
The most common way is to buy anti-fatigue eye drops to relieve dry eyes. In fact, this method is symptomatic rather than permanent, and is also easy to harm the eyes, because most of the eye drops on the market contain preservatives, you can use preservative-free artificial tears, depending on the comfort of your eye condition.
