Get kids outside: myopia, mental health and character all point outdoors
September 27, 2026 · 16 min read
An eye researcher, a social psychologist and an outdoorsman arrive from different directions at the same advice: children need more time outdoors and less indoor screen time. Outdoor time appears to protect eyesight, supports healthier development than phone-based childhood, and builds self-reliance.
The rules, numbers and steps worth keeping in front of you.
- Goldberg: one or two hours outdoors a day clearly beats zero for slowing nearsightedness in children.
- Goldberg: the optimal outdoor dose is not yet known; Huberman cites around two hours.
- Goldberg: most myopia develops before age 10, so start early.
- Goldberg: let children keep screen or book time, but move some of it outdoors.
- Goldberg: outdoor light is unlikely to change an adult's prescription.
- Haidt: no smartphone before high school and no social media until 16.
- Haidt: phone-free schools, with phones locked away all day, not kept in pockets.
- Haidt: give far more independence, free play and responsibility in the real world.
- Haidt: informal, kid-refereed games beat over-supervised leagues.
- Haidt: coordinate with other families, because a lone family imposes a cost on its child.
- Haidt: never choose a summer camp that allows phones.
- Haidt: try an awe walk, slowly, in a beautiful place, with nothing in your ears.
- Waddell: take kids into real nature with adults who know it; his view is personal experience, not research.
- Vision trouble calls for a pediatric eye exam; signs of anxiety, depression or self-harm call for a pediatrician or mental health professional.
This is the short form. The full insight has every expert's reasoning, their own words and the sources.
