===Degree===
The degree of myopia is described in terms of the [[optical power|power]] of the ideal [[corrective lens|correction]], which is measured in [[Dioptre|diopters]]:<ref name="Grosvenor">{{cite journal | vauthors = Grosvenor T | title = A review and a suggested classification system for myopia on the basis of age-related prevalence and age of onset | journal = American Journal of Optometry and Physiological Optics | volume = 64 | issue = 7 | pages = 545–54 | date = July 1987 | pmid = 3307441 | doi = 10.1097/00006324-198707000-00012 }}</ref>
* Myopia between −0.00 and −0.50 diopters is usually classified as [[emmetropia]].
* Low myopia usually describes myopia between −0.50 and −3.00 diopters.<ref name="Cline" />
* Moderate myopia usually describes myopia between −3.00 and −6.00 [[diopters]].<ref name="Cline" /> Those with moderate amounts of myopia are more likely to have [[pigment dispersion syndrome]] or [[glaucoma|pigmentary glaucoma]].<ref>[http://www.eyemdlink.com/Condition.asp?ConditionID=2 "Glaucoma."] {{webarchive|url=https://web.archive.org/web/20060819160824/http://www.eyemdlink.com/Condition.asp?ConditionID=2 |date=19 August 2006 }} EyeMDLink.com.
