An analysis of light that reaches the eye surface in an outdoor environment.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The global pandemic of myopia has become an urgent public health concern in recent years. Although the mechanism remains largely unclear, the importance of outdoor light exposure on myopia prevention is widely recognized. Outdoor light is more intense and has a different spectral composition compared to indoor lighting, which are believed to contribute to the suppression of myopia. However, due to modern lifestyles, even children find it difficult to spend time outdoors. To receive outdoor light efficiently is important, yet previous reports showed inconsistent findings on optimal thresholds for outdoor light exposure. One reason may be the lack of a standardized protocol for measuring light reaching the eye surface. In this study, we developed a novel measurement device using a 3D-printed mannequin head with a light sensor probe embedded at the eye position to mimic the human eye. We assessed the proportion of light that reached the mannequin's eye surface from different directions at various time points on a sunny day and evaluated the influence of different eyeglasses and lenses.
