Generally, eye dryness syndrome refers to dry eye disease. Dry eye disease is a group of conditions characterized by ocular discomfort symptoms and visual dysfunction caused by insufficient tear production, excessive tear evaporation, or abnormal tear composition. If discomfort occurs, timely medical consultation is recommended. Detailed analysis is as follows:

Dry eye disease may be associated with poor lacrimal gland function, meibomian gland dysfunction, long-term contact lens wear, prolonged use of electronic devices, ocular surgery or injury, and medication side effects. Patients may experience symptoms such as eye fatigue, foreign body sensation, and dryness. Some patients may also develop burning sensation, aching, redness, pain, and photophobia. Artificial tears or autologous serum can be used to supplement tear components, promote tear secretion, and reduce ocular surface inflammation. For patients with severe symptoms, surgical treatments such as punctal occlusion or autologous free submandibular gland transplantation may be considered under a doctor's guidance.

Maintaining ocular moisture, avoiding prolonged eye use, practicing good eye hygiene, avoiding extended contact lens wear, undergoing regular eye examinations, and actively treating systemic diseases can help prevent dry eye disease.
