Conjunctival xerosis is a phenomenon of conjunctival dryness that occurs primarily due to lesions in the conjunctival tissue itself and has a variety of causes. Under normal conditions, the lacrimal glands and conjunctival cuvettes secrete tears to keep the conjunctiva moist on a regular basis, but once this moisturizing function is disrupted, conjunctival dryness occurs. Conjunctival dryness can be divided into epithelial conjunctival dryness and substantive conjunctival dryness. Cod liver oil drops are used clinically, along with antibiotic solutions and eye ointments to prevent and treat secondary infections, corneal ulcers and corneal softening. Patients with conjunctival dryness are suitable to eat foods rich in vitamin A, foods that brighten the eyes and clear the liver, and foods rich in high quality protein. Avoid eating foods that weaken vision, spicy and stimulating foods, and fried foods. For example, the following foods should be eaten with caution: 1, lettuce lettuce in a certain substance in the optic nerve has a stimulating effect, ancient books record that lettuce more food to make people eyes paste, stop eating for a few days, it can recover on its own, so the lack of vitamin A patients are prone to eye disease, should not eat more.
