VISUAL GUIDE 1 / 3
One routine, two different clinical questions
Before myopia develops
Outdoor-time interventions may reduce new myopia. That is the prevention question.
After myopia develops
Evidence about slowing established progression is less certain. Keep the child’s clinical treatment and monitoring plan.
About two hours daily is a practical goal, not a proven protective threshold for each child or a promise that a prescription will remain stable.
