    In plain language: Including 25 studies and more than 34,000 participants, this analysis confirmed that increased daily outdoor time is significantly associated with a reduced risk of myopia onset, and that about 76 additional minutes of outdoor activity per day can cut the risk by 50%. It established that outdoor light intensity is 100–1,000 times that of indoors, and that light-stimulated dopamine release is the core mechanism.

    In plain language: A Taiwan school-based cluster RCT (16 schools, 693 children) that pioneered the finding that mandatory outdoor activity during recess can significantly slow myopia progression (myopic shift of 0.35D vs 0.47D in controls, with a 54% reduction in the risk of rapid progression; the same team's 2013 study showed an annual myopia incidence of 8.4% in the intervention group vs 17.6% in controls). It laid the evidence-based foundation for the global consensus that "increasing outdoor time prevents myopia" and has been widely cited by subsequent research.

    Dolgin E. The myopia boom. Nature, 2015, 519(7543): 276–278. DOI ↗

    In plain language: A Nature feature article that systematically reviews the global myopia boom and its environmental drivers, identifying insufficient outdoor light exposure as the key reason for high myopia rates; it proposes that children need to spend roughly 3 hours a day at light levels of at least 10,000 lux to effectively prevent the onset and progression of myopia. An authoritative basis for the "outdoor light dose" concept.

    In plain language: A real-world study of Taiwan's "Outdoor 120 Every Day" program (120 minutes outdoors daily), using the rate of poor uncorrected visual acuity as the measure. After the program's implementation, the long-term rising trend in the rate of poor vision among elementary school students was reversed, falling from 50.01% to 46.12%. It proves that outdoor intervention is feasible and effective at a large-population level, providing national-scale population evidence for this book's behavioral-intervention recommendations.

    Rose KA, Morgan IG, Smith W, et al. Myopia, lifestyle, and schooling in students of Chinese ethnicity in Singapore and Sydney. Arch Ophthalmol, 2008, 126(4): 527–530. DOI ↗

    In plain language: A classic cross-city comparative study. Among ethnic Chinese children aged 6–7, the myopia rate was only 3.3% in Sydney but as high as 29.1% in Singapore; the key difference lay not in near-work load (Sydney children actually spent more time reading) but in outdoor time—13.75 hours per week versus 3.05 hours. It powerfully demonstrates that outdoor time is a core modifiable factor in myopia prevention and control, independent of study load, supporting this chapter's central theme that "outdoor light is the main force; indoor lighting is the understudy."

    Karouta C, Thomson K, Morgan I, Ashby R. (2025). Light Inhibits Lens-Induced Myopia through an Intensity-Dependent Dopaminergic Mechanism. Ophthalmology Science, 5(5): 100779. DOI ↗

    In plain language: A chick lens-induced myopia model study with two major findings: ① Light inhibits myopia through an intensity-dependent dopaminergic mechanism—axial length grew rapidly at 500 lux, was significantly slowed at 20,000 lux, and was suppressed by about 50% at 40,000 lux (per the paper's figure data); the higher the light intensity, the more retinal dopamine (DOPAC) is released, providing molecular-mechanism-level evidence for "bright outdoor light for myopia prevention and control." ② Using the "Total Effective Photons" method, the paper also compared the photoreceptor activation patterns of fluorescent light (500 lux), white LED (10,000 lux), halogen light (10,000 lux), and sunlight (90,000 lux): LED and sunlight showed similar activation patterns (balanced activation across cone types), while fluorescent and halogen light skewed markedly toward long-wavelength cones and away from natural light—providing direct support for Chapter 5's "Question 2: Photoreceptor Activation Patterns" and for the lamp-selection logic that "high-quality full-spectrum LEDs come closest to sunlight."

    In plain language: A monochromatic-light refractive development study in rhesus monkeys (the animal model closest to the human visual system), demonstrating that infant monkeys raised under long-wavelength red lighting developed refraction clearly biased toward hyperopia. This suggests that the long-wavelength (red) component of the spectrum can guide the eye to develop in an anti-myopia direction, providing primate experimental evidence for this book's "red-enriched" lighting strategy.

    Gawne TJ, Siegwart JT Jr, Ward AH, et al. The wavelength composition and temporal modulation of ambient lighting strongly affect refractive development in young tree shrews. Exp Eye Res, 2017, 155: 75–84. DOI ↗

    In plain language: A tree shrew study confirming that the wavelength composition of ambient lighting strongly influences the direction of refractive development: tree shrews raised under narrow-band red light remained persistently hyperopic. This suggests that spectral shape itself is the "conducting signal" of eyeball development, providing experimental support for Chapter 5's principle that "spectral shape is the first criterion in choosing a lamp."

    Gawne TJ, Ward AH, Norton TT. Juvenile Tree Shrews Do Not Maintain Emmetropia in Narrow-band Blue Light. Optom Vis Sci, 2018, 95(10): 911–920. DOI ↗

    In plain language: A narrow-band blue-light study in tree shrews, finding that juvenile tree shrews could not maintain emmetropia in narrow-band blue light—first shifting briefly toward hyperopia, then gradually sliding into myopia. From the opposite direction, this confirms that a spectral shape with "a high share of blue light and insufficient red" is unfavorable for refractive development, and together with [18] and [19] forms an evidence chain showing that "whether red light is sufficient determines which way the eyeball grows."

    Swiatczak B, Schaeffel F. Myopia: why the retina stops inhibiting eye growth. Sci Rep, 2022, 12(1): 21704. DOI ↗

    In plain language: A human experiment at the University of Tübingen, Germany. Participants watched digitally filtered films in which only the relative sharpness of red versus blue imagery was subtly adjusted (simulating the human eye's longitudinal chromatic aberration), while the picture content was virtually identical. Results: when the red imagery was sharper, emmetropes' axial lengths shortened within 45 minutes (with choroidal thickening); when the blue imagery was sharper, axial lengths elongated; and the retinas of myopes responded sluggishly to the "stop growing" signal. This directly confirms that the human retina judges the direction of defocus by comparing the sharpness of the red and blue ends and regulates axial growth accordingly, providing human evidence for Chapter 5's spectral mechanism of "high red-light share → myopic defocus → inhibition of axial length growth."

    In plain language: The official white paper of the International Myopia Institute (IMI), systematically reviewing randomized controlled trial evidence across all categories of myopia-control interventions (optical, pharmacological, environmental/behavioral, colored light, and surgical). It lists RLRL as one of the effective interventions for delaying myopia onset in high-risk children and provides guidance on its potential and safety monitoring; it also includes a dedicated section summarizing the evidence on undercorrection—three well-designed RCTs consistently show that undercorrection of 0.50–0.75D offers no benefit and may accelerate myopia progression, emphasizing that myopia must be fully corrected.

    In plain language: A single-center randomized controlled trial of 200 myopic children aged 6–15, directly comparing the axial-control effects of three power levels: 0.37 mW, 0.60 mW, and 1.20 mW. After 6 months, all three groups significantly outperformed the control group (axial length change +0.04/0.00/-0.04 mm vs. +0.27 mm in controls; choroidal thickening of 22.63/36.17/42.59 μm), with no statistically significant difference in efficacy among the groups (adjusted P>0.05), and no adverse events were observed at any of the three power levels. This provides direct evidence for Chapter 6's principles of "low power for the long term" and "combination therapy over increasing power."

    In plain language: A longitudinal OCT study of children receiving red-light therapy, tracking choroidal changes continuously for 12 months. Choroidal thickening followed a dynamic curve of "an initial peak (1 month, +14.76 μm), then a decline (3 months, +5.29 μm; 6 months, +1.54 μm), followed by a steady rise (12 months, +9.09 μm)," while the choroid in the control group continued to thin. The degree of choroidal thickening at 3 months predicted 12-month myopia-control outcomes (accuracy 71%-79%). This provides the mechanistic basis for Chapter 6's "monthly follow-ups during the first 3 months" and evidence that "the 3-month choroid is a weather forecast for 12-month efficacy."

    In plain language: A PRISMA-compliant systematic review and meta-analysis (PROSPERO registered; literature search through August 2025) including 11 randomized controlled trials covering 2,190 myopic children's eyes, for the first time comparing the effects of mainstream myopia interventions on choroidal thickness on the same scale: repeated low-level red light produced the strongest thickening effect (mean 24.1 μm, 95% CI 19.8–28.5)—2.3 times that of low-dose atropine (10.6 μm) and 1.8 times that of orthokeratology lenses (13.3 μm) and microlens defocus spectacle lenses (13.2 μm); the evidence for most interventions was of high certainty. This confirms red light as currently the strongest myopia intervention for choroidal thickening, providing cross-comparison evidence for Mechanism 1 in Chapter 6.

    In plain language: A multicenter RCT of children with high myopia (≤-6.00D), involving 202 children aged 7–12: in the red-light group, axial length regressed by an average of 0.11 mm at 12 months (versus 0.32 mm growth in controls), and 59% of children experienced axial length regression exceeding 0.05 mm (versus 0 in controls). Choroidal thickening could not fully explain the magnitude of regression, suggesting the involvement of other mechanisms such as scleral remodeling.

    In plain language: The CYPRESS study, a prospective randomized controlled double-masked trial across 14 clinical centers in North America with 256 myopic children aged 6–10. Diffusion optics (DOT) lenses scatter light through thousands of microscopic dots, reducing retinal contrast; at 12 months, myopic refractive progression was slowed by 74% and axial elongation by 50%. The mechanism derives from retinal contrast theory (the finding that high-contrast signals, as in Bornholm eye disease, accompany high myopia), confirming that reducing retinal contrast can slow axial elongation—providing optical-intervention counter-evidence for Chapter 5's point that "homogenizing the light environment (turning on the ceiling light) reduces high-contrast stimulation."

    In plain language: The 5-year follow-up report of the LAMP study. Continuous use of 0.05% atropine for 5 years showed good myopia control; if myopia progressed after discontinuation, as-needed (PRN) re-initiation of 0.05% atropine could effectively control progression. This confirms the long-term efficacy of low-dose atropine and the effectiveness of an as-needed restart strategy.

    In plain language: A prospective observational study showing that just one week of intensive outdoor activity significantly increased choroidal thickness in Japanese schoolchildren—direct evidence that outdoor exposure produces rapid, measurable structural changes in the eye.

A note on the 11 entries without DOI links: they are Chinese-language journal articles, government survey reports, or national standards that do not register DOIs — we list them in full so readers with access to Chinese databases (CNKI, Wanfang) can locate them. Every other entry's DOI was individually verified against the Crossref registry in October 2026. Superscript numbers in the book's main text correspond to the [#] numbers here. References [9][16][30][38][39][46][47][59][72][95] are further-reading suggestions not directly cited in the main text.
