A Review On Pharmacological Therapy On Screentime

Screen time has become an essential part of daily life, especially among children, adolescents, and young adults, for education, communication, work, and entertainment. However, excessive and prolonged use of smartphones, computers, tablets, and televisions can negatively affect physical and mental health. Common problems include digital eye strain, dry eyes, blurred vision, headaches, neck and shoulder pain, poor posture, reduced physical activity, sleep disturbances, stress, and reduced concentration. Blue-light exposure at night may suppress melatonin production and disturb the sleep–wake cycle, while reduced blinking during prolonged screen use can increase ocular dryness and discomfort. This review discusses the causes, risk factors, molecular mechanisms, epidemiology, effects, and management of excessive screen time. Pharmacological treatment mainly provides symptomatic relief, while preventive measures such as regular breaks, the 20-20-20 rule, adequate sleep, exercise, proper posture, and reducing unnecessary screen use are important for maintaining overall health.
