Effect of High-Energy Visible Light-Filtering Spectacle Lenses on Distance Contrast Sensitivity.

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
Purpose: High-energy visible (HEV) light-filtering spectacle lenses, which selectively decrease transmission of short wavelength visible light, have been increasing in popularity in recent years despite much debate about their potential ocular benefits. This study reports on the effect of HEV light-filtering spectacle lenses on distance contrast sensitivity (CS). Patients and Methods: The study included 30 healthy young adults aged 18 to 35 years. Binocular CS was measured with the Pelli-Robson test in both photopic and mesopic illumination using three commercially available HEV light-filtering spectacle lenses and a clear uncoated control lens. Data were analyzed with descriptive and inferential statistics. Results: There was no difference in CS measurements among the four test lenses in either photopic (x Conclusion: The HEV light-filtering spectacle lenses have no clinically meaningful effect on distance CS in young adults in both photopic and mesopic illumination. These results would be useful for eye care personnel when prescribing HEV light-filtering spectacle lenses.
