Pilestone glasses for color blindness: the effect on chromatic discrimination in subjects with congenital color deficiency.
Article in International ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe purpose of this study was to assess how well the Pilestone color vision glasses worked to improve test results for color deficiency based on the Ishihara color vision test.
methodsFollowing their consent, sixteen people with color vision defects were enrolled. The Ishihara test was used to evaluate color vision. The incorrect scores were noted. After using Pilestone glasses for color vision impairment, the test was repeated.
resultsThe median error score was 20 (18-20) on Ishihara. The median error scores were reduced to 8 (1-18.75). Ten patients were satisfied with result of intervention (62.5%) while (37.5%) were non-satisfied.
conclusionThis study demonstrates that individuals were able to pass the color vision tests and that the Pilestone glasses which is the cheapest glasses in the market decreased error scores. Additionally, it might enhance the subjective look of the colorful things in the surrounding.
