Prolonged television or computer viewing negatively affects vision
Multiple studies indicate that prolonged television, computer, or digital device viewing negatively affects vision, contributing to conditions such as myopia, dry eye disease, and digital eye strain.
The claim is specific, empirical, and falsifiable, passing Step 0. The retrieved literature includes multiple observational studies, meta-analyses, and clinical investigations consistently showing that prolonged screen time and near-work activities are associated with negative visual outcomes, including myopia progression, dry eye disease, and digital eye strain. No papers refute the claim, leading to a SUPPORTED verdict.

Modifiable behaviors such as appropriate screen and near-work viewing distances were significantly associated with lower odds of myopia.
