The Claim
No statistically significant difference in axial length growth was observed among children classified by levels of near-work, sports, or outdoor time over a one-year study period.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Over one year, children who spent more time on near-work, sports, or outdoors showed no measurable difference in the growth of their eye length.
See the scientific wording
No statistically significant difference in axial length growth was observed between subgroups of children classified by near-work, sports, or outdoor time during the study period, suggesting that lifestyle factors may not acutely influence eye growth over a single year in this population.
When daylight is low, the retina releases less dopamine, which allows the back of the eye to soften and stretch longer. When daylight is high, dopamine keeps the back of the eye stiff, preventing it from growing too much.
What the research says
1 studyStudy: Myopia Progression Risk: Seasonal and Lifestyle Variations in Axial Length Growth in Czech Children
Kids who read more, played sports, or spent time outside didn't grow their eyeballs faster or slower than others over the year — their eye growth was about the same. But kids who read a lot started with longer eyes to begin with.
