===Refractive===
Refractive amblyopia may result from [[anisometropia]] (unequal refractive error between the two eyes).<ref>{{cite journal | first1 = Robert F.| last1 = Rutstein | first2 = David | last2 = Corliss | name-list-style = vanc |title=Relationship between Anisometropia, Amblyopia, and Binocularity|journal=Optometry & Vision Science|date=April 1999|volume=76|issue=4| pages = 229–33 | doi = 10.1097/00006324-199904000-00026 | pmid = 10333185}}</ref><ref>{{cite journal | vauthors = Weakley DR | title = The association between nonstrabismic anisometropia, amblyopia, and subnormal binocularity | journal = Ophthalmology | volume = 108 | issue = 1 | pages = 163–71 | date = January 2001 | pmid = 11150283 | doi = 10.1016/s0161-6420(00)00425-5 }}</ref> Anisometropia exists when there is a difference in the [[refractive error|power]] between the two eyes. The eye which provides the brain with a clearer image typically becomes the dominant eye. The image in the other eye is blurred, which results in abnormal development of one half of the visual system. Refractive amblyopia is usually less severe than strabismic amblyopia and is commonly missed by [[primary care physician]]s because of its less dramatic appearance and lack of obvious physical manifestation, such as with strabismus.<ref name=AAFP>{{cite journal | vauthors = Simon JW, Kaw P | title = Commonly missed diagnoses in the childhood eye examination | journal = American Family Physician | volume = 64 | issue = 4 | pages = 623–8 | date = August 2001 | pmid = 11529261 | url = http://www.aafp.org/afp/20010815/623.html | access-date = 28 August 2005 | archive-date = 12 September 2005 | archive-url = https://web.archive.org/web/20050912000156/http://www.aafp.org/afp/20010815/623.html | url-status = dead }}</ref> Given that the refractive correction of anisometropia by means of spectacles typically leads to different image magnification for the two eyes, which may in turn prevent binocular vision, a refractive correction using [[contact lens]]es is to be considered. Also [[Refractive surgery#Children|pediatric refractive surgery]] is a treatment option, in particular if conventional approaches have failed due to [[aniseikonia]] or lack of compliance or both.<ref>{{cite journal | vauthors = Astle WF, Rahmat J, Ingram AD, Huang PT | title = Laser-assisted subepithelial keratectomy for anisometropic amblyopia in children: outcomes at 1 year | journal = Journal of Cataract and Refractive Surgery | volume = 33 | issue = 12 | pages = 2028–34 | date = December 2007 | pmid = 18053899 | doi = 10.1016/j.jcrs.2007.07.024 | s2cid = 1886316 }}</ref>

Frequently, amblyopia is associated with a combination of anisometropia and strabismus. In some cases, the vision between the eyes can differ to the point where one eye has twice average vision while the other eye is completely blind.
