Computer vision syndrome, or digital eye strain, is a cluster of eye and vision problems from prolonged screen use — reduced blinking, sustained close-up focusing, glare, and poor viewing posture. It's increasingly common with rising smartphone and computer use across all ages.
Symptoms
- Eye strain and tired, sore eyes
- Headaches around forehead/temples
- Blurred vision after long sessions
- Dry, irritated eyes
- Difficulty refocusing near/far
- Neck and shoulder pain
Causes & risk factors
- Prolonged continuous screen use without breaks
- Reduced blink rate while focused on a screen
- Poor lighting or screen glare
- Screens positioned too close or at an awkward angle
- Uncorrected refractive errors
Diagnosis
- Discussion of screen habits and symptom pattern
- Comprehensive eye exam to check for uncorrected refractive error
- Assessment of focusing and eye coordination
- Tear film evaluation, since dry eye often overlaps
Treatment options
- The 20-20-20 rule — every 20 minutes, look 20 feet away for 20 seconds
- Conscious, more frequent blinking
- Lubricating drops for dryness
- Adjusting screen position and lighting
- Regular breaks; updated glasses prescription if needed
When to seek urgent care
Not an emergency on its own, but see an eye doctor for persistent blurred vision that doesn't improve with breaks, worsening headaches, double vision, or eye pain.
Frequently asked questions
Does digital eye strain cause permanent damage?
No — it causes uncomfortable but temporary symptoms, though it can point to an underlying issue like an uncorrected refractive error worth checking.
Do blue-light glasses help?
Evidence is limited. Good screen habits and the 20-20-20 rule have more consistent evidence behind them.
Can children get digital eye strain?
Yes — encouraging regular breaks and outdoor time helps as more children use devices for schoolwork.
