Proper reading distance allows the eyes to focus comfortably on text without excessive effort or awkward posture. It varies slightly with age and task but has typical ranges.
General Guidance
For adults, a reading distance of about forty centimetres, or roughly arm’s length from knuckle to elbow, is usually comfortable. Children often hold material too close, so encouraging a slightly greater distance helps reduce strain.
- Very close working distances increase focusing and convergence demand
- Presbyopic adults may need stronger reading powers for closer tasks
- Large print or increased zoom allows a more relaxed distance
- Music stands, document holders, or book rests can help maintain position
Optimising Comfort
Combine appropriate distance with good lighting, upright posture, and regular breaks. If you struggle to see clearly at a normal reading distance, an eye examination is advisable.
- Persistently short working distance in children may signal uncorrected short‑sightedness
- Adjust multifocal or varifocal lens fitting if you find yourself tilting your head excessively
- Use task lighting that illuminates the page without glare
- Discuss specific hobby or work distances with your optometrist for tailored prescriptions
