Eye fatigue is tired, heavy, or strained vision after visual tasks. It is often called asthenopia and is very common in modern screen‑based lifestyles.
Key Triggers
Prolonged near work without breaks, uncorrected or under‑corrected prescriptions, and poor workstation ergonomics are leading causes. Dry eye, inadequate lighting, and binocular vision anomalies also make the eyes tire more easily.
- Symptoms include heaviness, burning, blur, and headaches after tasks
- Children may rub their eyes, yawn, or lose concentration with near work
- Digital devices reduce blink rate and increase surface strain
- Stress, lack of sleep, and systemic illness lower overall visual stamina
Prevention and Management
Following the twenty-twenty-twenty rule, adjusting screen position, ensuring correct glasses, and managing dryness greatly reduce fatigue. Persistent or severe symptoms should be assessed for underlying eye or health problems.
- Task-specific lenses can optimise focus for computer distances
- Regular breaks and posture checks help both eyes and neck
- Hydration and general wellbeing play supportive roles
- Early intervention prevents discomfort from becoming a chronic problem
