Difference between revisions of Lens-induced myopia

A core tenant of EM is that doing [[near work]] in lenses designed for [[distance work]] causes myopia progression.  Even if hyperopic blur is not induced by the lenses, the [[accommodation]] system is being constantly stressed and this encourages [[eye axial lengthening]].  This is supported by the fact that both [[bifocals]] and [[multifocals]], which allow the eye to use less accommodation to do near work, are protective against myopia progression <ref name="Can Bifocals Slow Myopia Progression?">{{Cite journal |last=Gw |first=Fulk |last2=La |first2=Cyert |date=1996 Dec |title=Can Bifocals Slow Myopia Progression? |url=https://pubmed.ncbi.nlm.nih.gov/9286316/ |journal=Journal of the American Optometric Association |language=en |volume=67(12) |pages=749-754 |pmid=9286316 |via=PubMed}}</ref><ref name="Myopia Progression Control Using Bifocal Contact Lenses">{{Cite journal |last=Aller |first=Thomas |last2=Grisham |first2=David |date=2000-12 |title=(OR-103)MYOPIA PROGRESSION CONTROL USING BIFOCAL CONTACT LENSES: Poster # 92 |url=https://journals.lww.com/optvissci/Citation/2000/12001/_OR_103_MYOPIA_PROGRESSION_CONTROL_USING_BIFOCAL.311.aspx |journal=Optometry and Vision Science |language=en-US |volume=77 |issue=12 |pages=187 |issn=1538-9235}}</ref><ref name="Myopia Progression With Biofocal Soft Contact Lenses - A Twin Study">{{Cite journal |last=Aller |first=Thomas |date=2002-12-13 |title=MYOPIA PROGRESSION WITH BIFOCAL SOFT CONTACT LENSES - A TWIN STUDY.: Poster # 142 |url=https://journals.lww.com/optvissci/Citation/2002/12001/MYOPIA_PROGRESSION_WITH_BIFOCAL_SOFT_CONTACT.346.aspx |journal=Optometry and Vision Science |language=en-US |volume=79 |issue=12 |pages=179 |issn=1538-9235}}</ref><ref name="Myopia Control With Bifocal Contact Lenses: A Randomized Clinical Trial">{{Cite journal |last=Aller |first=Thomas |last2=M |first2=Liu |last3=Cf |first3=Wildsoet |date=2016 Apr |title=Myopia Control With Bifocal Contact Lenses: A Randomized Clinical Trial |url=https://pubmed.ncbi.nlm.nih.gov/26784710/ |journal=Optometry and Vision Science Supplement |language=en |volume=93(4) |pages=344-52 |pmid=26784710}}</ref><ref name="Effect of Bifocal Lenses on the Rate of Childhood Myopia Progression">{{Cite journal |last=Goss |first=D A |date=1986 Feb |title=Effect of Bifocal Lenses on the Rate of Childhood Myopia Progression |url=https://pubmed.ncbi.nlm.nih.gov/3953756/ |journal=American journal of optometry and physiological optics |language=en |volume=63(2) |pages=135-41 |pmid=3953756}}</ref>
