Note that the term ''diopter ratio'' is often used interchangeably for ''diopter gap''<ref>{{cite jake|https://endmyopia.org/the-diopter-ratio-trap-dont-favor-one-eye/|The Diopter Ratio Trap: Don’t Favor One Eye}}</ref>, for example when talking about reducing a correction while keeping the ''gap'' the same. This can also be expressed as a percentage difference between the two diopter values<ref>{{cite jake|https://endmyopia.org/reducing-diopter-ratio-diy-patching-solution-pro-topic/|Reducing Diopter Ratio: DIY Patching Solution (PRO TOPIC)}}</ref> (e.g. the <tt>0.5 dpt</tt> difference between the right and left eyes here is equivalent to <tt>0.5 dpt / |-1.5 dpt| = 0.33</tt> or 33%). | Note that the term ''diopter ratio'' is often used interchangeably for ''diopter gap''<ref>{{cite jake|https://endmyopia.org/the-diopter-ratio-trap-dont-favor-one-eye/|The Diopter Ratio Trap: Don’t Favor One Eye}}</ref>, for example when talking about reducing a correction while keeping the ''gap'' the same.

The general recommendation is that the diopter gap is constant across all lenses being used. However, some old EM articles show cases where differentials are equalized but normalized have a 0.25 D gap.<ref>https://endmyopia.org/progress-improving-centimeter-62-90/</ref> | The general recommendation is that the diopter gap is constant across all lenses being used.

Confusingly, diopter gap is also sometimes used to refer to the [[spherical equivalent]] difference between [[differentials]] and [[normalized]].<ref>https://endmyopia.org/pro-topic-managing-your-maximum-diopter-gap/</ref> | Confusingly, diopter gap is also sometimes used to refer to the [[spherical equivalent]] difference between [[differentials]] and [[normalized]].<ref>https://endmyopia.org/pro-topic-managing-your-maximum-diopter-gap/</ref> | ||
