A simple pair of glasses has spherical lenses of similar power.  If one eye is weaker than the other, or you have [[astigmatism]], lenses to compensate for that are more complex.  EM recommends that you start with small and even [[spherical reductions]] first, then after you've accomplished a few of those, then work on reducing complexity.

==Components==
There are three major components in your lens complxity.<ref name="EndMyopia Blog: How To Reduce Prescription Complexity">{{Cite web |title=Pro Topic: How To Reduce Prescription Complexity - Endmyopia |url=https://endmyopia.org/pro-topic-how-to-reduce-prescription-complexity/ |website=endmyopia.org |access-date=2020-06-05}}</ref>
===== Dipoter Ratio =====
The difference between your left eye and right eye spherical correction. EM recommends that you start reducing the dipter ratio only you have done with astigmatism.<ref name="EndMyopia Blog: How To Reduce Prescription Complexity">{{Cite web |title=Pro Topic: How To Reduce Prescription Complexity - Endmyopia |url=https://endmyopia.org/pro-topic-how-to-reduce-prescription-complexity/ |website=endmyopia.org |access-date=2020-06-05}}</ref>
===== Astigmatism Correction =====
You may reduce your close-up astigmatism correction first, then work on reducing your astigmatism for distance.
===== Astigmatism Correction Difference =====
The difference between your left eye and right eye cylinder correction.
