Lens-Viewpoint Extraction Method for Personalized Progressive Addition Lens Fitting.
Article in Translational vision science & technology, 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
Purpose: To validate the accuracy of a lens-viewpoint extraction method and demonstrate its feasibility for tracking users' visual behavior on progressive addition lenses (PALs). This aims to provide a quantifiable fitting solution for PAL wearers in the future. Methods: We evaluated a method using eye-tracking technology to extract the viewpoint on the lens, implemented with a self-made setup. Accuracy verification experiments were performed using a mechanical artificial eye, and a clinical test on 10 subjects was performed to assess the accuracy of the method and explored its feasibility. Results: The accuracy of the lens-viewpoint extraction method was verified to be 0.21 ± 0.06 mm and 0.30 ± 0.07 mm on the lens in the mechanical artificial eye experiment and clinical test, respectively. An exemplary analysis of user eye behavior on the lens was provided. Conclusions: These results demonstrate that the lens-viewpoint extraction method achieves high accuracy and is feasible for tracking users' personalized visual habits on the lens. Translational Relevance: The lens-viewpoint extraction method introduced in this study shows significant potential for providing a quantifiable solution to improve wearing comfort for the presbyopia population, holding important translational value in the field of precision optometry.
