Extended screen time can contribute to dry, tired eyes, headaches, and blurred vision, particularly when breaks are infrequent. It can also disrupt sleep patterns when bright devices are used late at night.
Short-term Effects
People often notice sore, gritty eyes, difficulty focusing into the distance after prolonged near work, and increased light sensitivity. These symptoms are usually reversible with rest and better habits.
- Reduced blink rate promotes tear evaporation and dryness
- Prolonged close work stresses the focusing system, especially in younger people
- Glare and small text magnify visual demand
- Children may hold screens very close, increasing effort further
Healthy Screen Habits
Moderating screen use, especially before bedtime, and encouraging outdoor activity benefit both eye comfort and general health. Regular eye examinations ensure any underlying issues are addressed.
- Encourage children to take frequent breaks and spend time outdoors daily
- Consider device night modes or reduced brightness in the evening
- Use lubricating drops if advised for dry eye symptoms
- Discuss persistent discomfort or visual changes with an eye care professional
