== Myopic defocus is most effective in the evening ? == | |||
A really interesting result that watching TV in the evening with undercorrection will magically cure myopia ??!!?? | |||
{{cite journal| author=Moderiano D, Do M, Hobbs S, Lam V, Sarin S, Alonso-Caneiro D | display-authors=etal| title=Influence of the time of day on axial length and choroidal thickness changes to hyperopic and myopic defocus in human eyes. | journal=Exp Eye Res | year= 2019 | volume= 182 | issue= | pages= 125-136 | pmid=30926510 | doi=10.1016/j.exer.2019.03.019 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=30926510 }} | |||
Highlights | |||
* Ocular response to defocus varies depending on the time of day in human subjects. | |||
* Evening exposure to myopic defocus causes a larger reduction in axial length. | |||
Also {{cite journal| author=Nickla DL, Jordan K, Yang J, Totonelly K| title=Brief hyperopic defocus or form deprivation have varying effects on eye growth and ocular rhythms depending on the time-of-day of exposure. | journal=Exp Eye Res | year= 2017 | volume= 161 | issue= | pages= 132-142 | pmid=28596085 | doi=10.1016/j.exer.2017.06.003 | pmc=5557081 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=28596085 }} | |||
It is generally accepted that myopic defocus is a more potent signal to the emmetropization system than hyperopic defocus: one hour per day of myopic defocus cancels out 11 h of hyperopic defocus. | |||
