The Claim
Daily exposure to natural green landscapes for two hours over 10 weeks is associated with a mean improvement of 0.2 logMAR in uncorrected distance visual acuity among adults with mild to moderate myopia.
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.
Adults with mild to moderate myopia who spend two hours per day in natural green environments for 10 weeks show a measurable improvement in their uncorrected distance vision by 0.2 logMAR units.
See the scientific wording
Daily exposure to natural green landscapes for two hours over 10 weeks is associated with a mean improvement of 0.2 logMAR in uncorrected distance visual acuity among adults with mild to moderate myopia, suggesting a potential link between green environment exposure and visual function.
Looking at green landscapes for two hours each day exposes the eyes to specific green wavelengths that trigger dopamine release in the retina. This dopamine reduces harmful oxidative stress in retinal cells, allowing photoreceptors to transmit visual signals more efficiently, which sharpens distance vision.
What the research says
1 studyPeople with mild nearsightedness who spent two hours a day in green spaces like rice fields for 10 weeks saw a small but real improvement in their distance vision — without glasses. The study suggests being around green plants may help the eyes relax and work better.
