'''Lens-induced myopia''' is the researched phenomenon <ref>[https://scholar.google.com/scholar?hl=en&q=lens+induced+myopia Google Scholar list of Lens Induced Myopia studies]</ref> that wearing corrective lenses seems to cause myopia to worsen/progress. Typically this occurs when lenses are either too [[overprescribed]], or when someone wears glasses meant for [[distance vision]] during [[close-up]] work. This is speculated to result in [[hyperopic defocus]] from accommodative load, the mechanism likely to be the cause of lens-induced myopia.<ref name="Proteomic analysis of chick retina during early recovery from lens‑induced myopia"> | '''Lens-induced myopia''' is the researched phenomenon<ref>[https://scholar.google.com/scholar?hl=en&q=lens+induced+myopia Google Scholar list of Lens Induced Myopia studies]</ref> that wearing corrective lenses seems to cause myopia to worsen/progress.
