Is it true that sitting close to a screen regularly causes short-sightedness?
No. The scientific literature on whether sitting close to screens regularly causes short-sightedness remains contested. While some cross-sectional studies and reviews report a positive association between screen time and myopia risk, authoritative reviews and other longitudinal and systematic analyses characterize the evidence as weak, inconsistent, or non-significant.
