Clinical Scorecard: Myopia: Screen and Outdoor Time

At a Glance

Key Highlights

• Children spending at least 90 to 120 minutes outdoors daily have significantly lower myopia risk.
• Myopia-preventing signals are strongest when outdoor breaks follow sustained near work.
• Practical screen habits include using larger screens, avoiding screens in bed, and encouraging voice commands.

Guideline-Based Recommendations

Diagnosis

• Assess myopia risk in school-aged children considering outdoor activity and near work habits.

Management

• Encourage at least 2 hours of outdoor activity daily, including free play and family walks.
• Advise breaks of 3 to 5 minutes outdoors after prolonged near work (no more than 15 minutes for handheld devices, 50 minutes for desktop).
• Promote practical screen use habits: larger screens, no screens in bed, avoid reading in cars, use voice commands.

Monitoring & Follow-up

• Monitor children's outdoor activity duration and near work patterns to guide myopia control strategies.

Risks

• Excessive near work without adequate outdoor breaks may increase myopia progression risk.
• Late-night screen use and close viewing distances may contribute to myopia development.

Patient & Prescribing Data

School-aged children at risk of or with early myopia

Combining lifestyle modifications with evidence-based clinical options optimizes myopia control outcomes.

Clinical Best Practices

• Advise families on realistic, evidence-based outdoor activity goals and screen habits.
• Emphasize timing and length of breaks after near work to maximize myopia prevention.
• Avoid guilt-based messaging about screen time; focus on practical, achievable lifestyle changes.
