Focusing on color: How the eye chooses which wavelength to see best.
Article in Science advances, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Humans can see in exquisite detail despite the fact that the eyes' optics can only focus light at a single wavelength at a time. It remains an open question what wavelength is brought into best focus by the human eye. Here, we investigate this question. We used a custom optical apparatus to measure the eye's focusing response (accommodation) to a range of stimuli with different wavelength compositions. We then developed a biologically informed model of the measured responses. Conventional wisdom holds that accommodation works to maximize visual acuity, but our findings suggest otherwise. Rather, our results support alternative lines of evidence that accommodation is guided by chromatic mechanisms that maximize signal quality in a color-opponent channel. Our results challenge prevailing views of oculomotor control and can inform therapeutic interventions for slowing the development and progression of myopia.
