TV Headaches: Why Close Viewing Causes Pain and How to Prevent It

Sitting too close to the TV can trigger headaches via:

1. Eye strain (asthenopia): Excessive accommodation/convergence → ciliary muscle fatigue, orbital pain.
2. Poor posture: Forward head/neck flexion → cervicogenic headache.
3. Migraine trigger: Flicker, bright light, pattern glare in susceptible individuals.
4. Cognitive load/stress: Intense focus, emotional content → tension-type headache.

Prevention

• Viewing distance: ≥5× screen width (e.g., 6+ ft for 55″ TV).
• 20-20-20 rule: Every 20 min, look 20 ft away for 20 sec.
• Ergonomic seating: eye level at top third of screen, supported back.
• Adjust brightness/contrast to ambient light; bias lighting reduces glare.
• Limit session duration; take breaks.

If headaches persist despite optimization, consult an optometrist (refractive error, binocular vision) or neurologist (migraine, cervicogenic).
