Screen time and dry eye in medical students: A chain mediation mechanism of sleep-emotion
Dry Eye Syndrome (DES) is a prevalent condition affecting the eyes' tear film and surface, causing discomfort and visual disturbances. It results from insufficient tear production or rapid evaporation, leading to symptoms like dryness, irritation, burning, and blurred vision. Factors contributing to DES include environmental conditions (such as dry air), medical issues (like autoimmune diseases), aging, medications, and prolonged screen use.
Diagnosis involves a thorough eye examination and specialized tests to evaluate tear quantity and quality. Treatment options range from lifestyle adjustments (e.g., using humidifiers, taking breaks from screens) to artificial tears and prescription medications for severe cases. Managing underlying conditions is essential to prevent complications like corneal damage. Regular eye care is crucial for managing DES effectively and maintaining optimal visual health and comfort.
