Good normalized lenses allow the user to continue daily activities without impairment, except night time driving, for which [[20/20 correction|a higher correction]] is a very good choice. (Always ensure your eyesight meets the minimum legal requirement while driving.) Normalized lenses induce a small amount of [[myopic defocus]], which has been shown to reduce axial length in a clinical study.<ref>{{Cite journal |last=Read |first=Scott A. |last2=Collins |first2=Michael J. |last3=Sander |first3=Beata P. |date=December 2010 |title=Human Optical Axial Length and Defocus |url=https://iovs.arvojournals.org/article.aspx?articleid=2126435 |journal=Investigative Ophthalmology & Visual Science}}</ref> | ||
