Summary

This study is a systematic review that gathers and analyzes existing research on digital eye strain among people who learn or work online. It aims to find out how common the condition is, what factors increase the risk, and what strategies can help prevent or manage it. The review includes studies published from 2020 onward, focusing on observational and interventional research. No new treatments are tested; instead, the goal is to summarize current knowledge to guide future recommendations.
