Exploring healthcare professionals' experiences and perspectives on cessation support for people who use non-cigarette tobacco: a qualitative study.

Presbyopia affects approximately 80% of adults over 40 years and 100% of those over 60, yet fewer than 20% of those impacted in low- and middle-income countries have access to reading glasses. While presbyopia’s impact on general productivity is documented, its effect on the digital performance of community health workers (CHW) remains unexplored. This study demonstrates that providing reading glasses to CHWs with presbyopia nearly doubles the odds of accurate digital data entry (OR=1.92). While vision correction did not measurably improve task speed, it significantly reduced errors in simulated clinical tasks. Integrating near-vision screening and low-cost correction into health worker training is a scalable, cost-effective strategy to improve the quality of data transcription and the integrity of digital health systems. Study findings support policies that treat visual acuity as a fundamental component of workforce quality and patient safety.
