Purpose. A literature review reveals historical references to an association between migraine headache and refractive errors, but a lack of scientific evidence relating to these claims. Methods. In a masked case-controlled study, we investigated the four aspects of refractive errors that have been implicated in the literature as correlated with migraine: spherical refractive error, astigmatic refractive error, anisometropia, and uncorrected ametropia. We also compared the calculated scalar… 
Refractive Errors in Patients with Migraine Headache
TLDR
Migraine patients may have higher degrees of astigmatism, SE, and anisometropia, and they should have ophthalmological examinations regularly to ensure that their refractive errors are appropriately corrected.
The refractive errors and migraine headaches
TLDR
The results of this study showed higher rates of astigmatism in the migraine group than the control one, and people who experience migraine headaches should visit their optometrist to ensure that their refractive errors are appropriately corrected.
Subtle binocular vision anomalies in migraine

TLDR
People with migraine have on average a slightly higher prevalence of heterophoria and aligning prism, and reduced stereopsis compared with controls, but the differences are subtle and the data do not support the use of binocular vision interventions prescribed solely on the basis of the presence of migraine.
Role of Refractive Errors in Inducing Asthenopic Symptoms Among Spectacle Corrected Ammetropes
TLDR
Asthenopic symptoms are frequent and significant among spectacle corrected ammetropes, and lower degrees of refractive errors are more symptomatic.
Migraine with aura is associated with impaired colour vision: Results from the cross-sectional German DMKG headache study
TLDR
In this cross-sectional, population-based study on sensory functioning in migraine participants, colour vision was impaired interictally in MA compared to MwoA and controls.
BINOCULAR ANOMALIES AS A CAUSE OF HEADACHE
TLDR
This study comprised of 199 emmetropic patients of headache and aims to study various binocular attributes associated with headache, in absence of refractive error and other ocular inflammatory diseases.
Is Ciliary Muscle Affected in Migraine Patients with Aura and without Aura?
TLDR
It was found that the cycloplegic spherical equivalents values of patients with aura were lower than control patients, and further studies are needed to reveal whether migraine with aura is the trigger or the result of those attacks.
Prevalence of astigmatism in headache
TLDR
The prevalence of uncorrected low grade astigmatism among cases presenting with headache as the single complaint was 49.3% and the proportion of patients with age ranged from 14 to 35 years with a mean age of 22.85+6.43 years.
Pediatric patients at a high risk or headache of ocular origin: the HAMS Score (Hyperopia, Astigmatism, Myopia, and Strabismus)
TLDR
The index based on the most common ocular diagnoses (HAMS score) is effective, and it has practical application in identifying children and adolescent patients with a greater or lesser propensity for headaches of ophthalmic origin.

It is concluded that subtle sympathetic and parasympathetic pupil abnormalities persist in the inter‐ictal phase of migraine.
Why do we still not know whether refractive error causes headaches? Towards a framework for evidence based practice
TLDR
Five research questions are posited in the form of a framework for the development of evidence‐based practice in optometry and the treatment of headache, which identify four serious methodological and theoretical difficulties with studies to date that render it impossible to assess the relationship between refractive error and headache.

TLDR
The therapeutic use of precision‐tinted spectacles to reduce pattern glare (visual stress) and to help some migraine sufferers is described, and the link between migraine headache and pattern glare is striking.

TLDR
The migraine group tended to be a little more exophoric, but by most criteria they were able to compensate for their exophoria as well as the control group, and the most likely mechanism for the benefit from individually prescribed coloured filters in migraine is the alleviation of cortical hyperexcitability and associated pattern glare.

TLDR
It was found that for symptomatic patients, most optometrists would correct an anomaly if it reached the ‘cut off’ point above which the anomaly would be corrected over 50% of the time that it was encountered, and there was a large variation for each category, but it was clear that the presence or absence of symptoms was an important factor for most Optometrists when deciding whether to correct a small error.
Ametropia and Ocular Biometry in a U.K. University Student Population
TLDR
It is clear that a further study incorporating formal epidemiologic methods of analysis is required to address adequately the recent proposal that juvenile myopia develops principally from “myopiagenic” environments and is relatively independent of ethnicity.
High Myopia Progression and Visual Impairment in a Nonselected Group of Danish 14-Year-Olds Followed Over 40 Years
TLDR
The adult visual prognosis for working age appeared better than usually claimed, and there seems to be a correlation between degree of myopia at age 14 and consecutive visual loss, but it was not possible to identify subjects at high risk at that early age.
