Overall video quality was suboptimal. Videos by ophthalmologists had significantly higher quality scores than those by other creators. Healthcare professionals focused more on definitions, symptoms and risk factors of myopia, whereas non-healthcare professionals emphasised prevention and treatment outcomes. Ophthalmologists more frequently recommended corrective lenses (including both standard spectacles and specially designed lenses for myopia control) and low-dose atropine, whereas non-healthcare professionals favoured vision training.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Significant quality gaps exist in myopia prevention videos.
