The Study
Retinal Dopaminergic Activation and Oxidative Stress Reduction Induced by Green Landscape Exposure: Evidence from a Controlled Myopia Study
This study saw that people who spent time in green fields got better at seeing things far away, but it didn't test if the green fields were the reason. Maybe they just got more rest, or the weather was better, or they were more relaxed. We can't say for sure the green fields caused the improvement.
Analysis score
Maximum 72 for a cohort study.
Where the score came from
People with mild nearsightedness walked in green fields for two hours every day for 10 weeks and their vision got a little better.

Quality score
Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.
Key takeaways
Summary
Based on the study abstract and findings.
- 1This small improvement means people might need slightly weaker glasses, but it's not a cure for myopia.
- 2Vision improved by 0.2 logMAR on average after 10 weeks of daily green exposure.

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.
Adults with mild to moderate myopia who spend two hours daily in green landscapes for 10 weeks show improved visual acuity, linked to ocular relaxation and changes in dopamine and oxidative stress pathways.
Exposure to natural daylight increases dopamine release in the retina, which directly slows the lengthening of the eye and decreases the worsening of nearsightedness.
In adults with myopia, exposure to green light in the 495–570 nm range is linked to lower levels of oxidative stress markers and higher retinal dopamine activity.
