Posture influences how the eyes align with reading material or screens and affects muscle strain in the neck and shoulders. Poor posture can indirectly increase eye strain and discomfort.
Effects on Vision
Leaning too close, tilting the head, or twisting the neck alters the angle of view and may place you outside the optimal zone of your spectacles or screen. This can lead to blurred vision, headaches, and difficulty sustaining near work.
- Slouching often brings the eyes closer to the page, increasing focusing demand
- Incorrect posture may encourage one eye to do more work than the other
- Varifocal or occupational lenses rely on consistent head and eye position
- Neck and shoulder tension can exacerbate perceived eye strain
Maintaining Good Posture
Using an ergonomic chair, appropriate desk height, and well‑positioned screens or reading stands supports both visual and musculoskeletal comfort. Regular breaks to move and stretch complement good posture.
- Keep material at a comfortable distance and slightly below eye level
- Avoid prolonged twisted or hunched positions
- Discuss persistent discomfort with both eye care and occupational health professionals
- Children may need guidance on correct posture for homework and device use
