Prolonged screen use reduces blink frequency and increases ocular surface dryness and visual fatigue.
Practical ergonomic adjustments
The 20-20-20 rule — looking 20 feet away for 20 seconds every 20 minutes — allows the eye muscles to relax. Positioning screens slightly below eye level reduces exposed corneal surface area and moisture evaporation.
Nutrition and hydration
Omega-3 fatty acids and adequate general hydration support tear film stability. If dry eye discomfort or blurred vision persists, consult an optometrist for an individual assessment.
