Abstract This meta‐analysis investigates the effectiveness of outdoor activities in reducing onset myopia children and adolescents by analysing changes axial elongation spherical equivalent refractive error. Following PRISMA guidelines registered PROSPERO (CRD42024592971), study included randomized controlled trials (RCTs) observational studies. The eligibility criteria targeted aged 6 to 18 years with varying levels exposure. Primary outcomes were change. Studies assessed for quality using GRADE AMSTAR‐2 tools, data analysed Review Manager 5.4, random‐effects models applied when heterogeneity was significant. Fifteen studies (9 RCTs observational) included, a total 16 597 participants. Outdoor significantly reduced or delayed myopia, mean length difference −0.08 mm per year (95% CI: −0.09 −0.07) 0.16 diopters 0.07 0.25). These differences observed after 1 intervention sustained up 3 years, daily exposure ranging from 40 120 min. Heterogeneity moderate high, but sensitivity analyses confirmed robustness results.

In the past few decades, prevalence of myopia, where eye grows too long, has increased dramatically. The visual environment appears to be critical regulating growth. Thus, it is very important determine properties that put children at risk for myopia. Researchers have suggested intensity illumination and range distances which a child's eyes are exposed important, but this not been confirmed.

Purpose: To evaluate the impact of optical vs. illuminance factors and their duration-dependency on lens-induced hyperopia (LIH) in chick eyes. Methods: Hyperopia was induced one eye chicks (10 groups; n = 126) from day 1 after hatching until 8 using +10-diopter lenses with fellow eyes as controls. One group served control without any interventions. The remaining groups were exposed to 2, 4, or 6 hours unrestricted vision (UnV), high-intensity light (HL; 15,000 lux), both (HL + UnV). Ocular axial length (AL), refractive error, choroidal thickness measured days 1, 8. Inter-ocular difference (IOD experimental − contralateral eye) ± SEM used express outcome measures. Results: By 8, LIH decreased AL (−0.42 0.03 mm) produced hyperopic refraction (+3.48 0.32 diopters) thickening (+85.81 35.23 µm) (all P < 0.001). Exposure UnV reduced (i.e., refraction, shortening, thickening) a duration-dependent manner, whereas HL potentiated development manner. When combined, overpowered HL, resultant being close alone, except at hours, when shorter compared alone (P 0.03). Conclusions: Daily exposure UnV, altered manner producing competing signals. signal generated by generally stronger than combined exposure, yet longer durations affected drive for emmetropization UnV.
