The aim of this study was to establish the prevalence of refractive errors in Jordanian adults of working age, and to study the ocular biometric correlates of refractive error in this population. Refractive error and ocular biometry were measured in 1093 Jordanian adult subjects aged 17–40 years to determine the prevalence of refractive error, and explore structural correlations of ametropia. Refractive error was measured using a Grand‐Seiko GR‐3100K closed‐view infrared autorefractor. Ocular… 
RELATIONSHIP BETWEEN REFRACTIVE ERRORS AND OCULAR BIOMETRY COMPONENTS IN CARPET WEAVERS
TLDR
SE refraction in carpet weavers had a significant relation to the ocular components and variation in SE refraction may be due to the changes of these elements.
Association between Refractive Errors and Ocular Biometry in Iranian Adults
TLDR
In individuals aged 40-64 years, corneal power and axial length make the greatest contribution to spherical equivalent in high hyperopia and high myopia, and anterior segment biometric components have a more important role in hyperopia than myopia.
The prevalence of refractive errors among Saudi adults in Riyadh, Saudi Arabia
TLDR
The refractive error with the highest prevalence among Saudis was astigmatism, followed by myopia and hyperopia, and gender, region of origin, and spectacle wear were all observed to be highly correlated with higher rates ofRefractive error.
The prevalence of refractive errors among Saudi adults in Riyadh, Saudi Arabia
TLDR
The refractive error with the highest prevalence among Saudis was astigmatism, followed by myopia and hyperopia, and Gender, region of origin, and spectacle wear were all observed to be highly correlated with higher rates ofRefractive error.
Prevalence of Refractive Errors; the Yazd Eye Study
TLDR
More than half of the study population had refractive errors; the prevalence of myopia and astigmatism was higher than earlier studies in Iran and their high prevalence in this survey is important from a public health perspective.
Axial Length, Corneal Radius, and Age of Myopia Onset
TLDR
The AL of the eye was found to be more related to the refractive error than the CR, especially in subjects with moderate myopia, and a trend towards a shorter radius of curvature was observed in emmetropes or subjects with low myopia.
Refractive Error among the Elderly in Rural Southern Harbin, China
TLDR
Myopia, hyperopia and astigmatism increased with increasing age (p<0.001), and it was found that prevalence of refractive error weas associated with education.
The prevalence of refractive errors in college students in Israel.
TLDR
Myopia prevalence in Israeli college students is high, showing associations with Jewish, but not Arab, ethnicity, suggesting that ethnic factors may play a role in the refractive differences between Arabs and Jews.
Prevalence of Refractive Errors in a Population of Office-Workers in Buenos Aires, Argentina
TLDR
The present study shows the prevalence of refractive error and the age of first myopic spectacle prescription in a sample of Hispanic well educated office-workers and in this highly educated group, parental history of myopia and years of university education were independently related to myopia.
Prevalence of refractive conditions in the general population attending eye care clinics in the north of Portugal
TLDR
There seem to be evidence that myopia could be increasing among the younger age groups, and the prevalence of refractive conditions has been established for a large non-randomized sample of the Portuguese population for the first time.

TLDR
In this cross-sectional study of adult Mongolians, a much lower prevalence of myopia was found than in other East Asian populations studied to date, in marked contrast to data on Chinese people.

TLDR
The structural cause of adult-onset and adult-progression of myopia is vitreous chamber elongation, which is found to be associated with adult onset myopia and emmetropic eyes that remained refractively stable.

TLDR
The study design, sample size, and measurement methods ensure that the prevalence of age-specific and sex-specific refractive error can be estimated with reasonable accuracy in the target populations.

TLDR
These cross-sectional data show a general pattern of ocular growth, no change in corneal power, and crystalline lens thinning and flattening between the ages of 6 and 14 years, with girls tended to have steeper corneas, stronger crystalline lenses, and shorter eyes compared with boys.
The relationship between ocular dimensions and refraction with adult stature: the Tanjong Pagar Survey.
TLDR
Although taller persons are more likely to have longer globes, they also tend to have deeper anterior chambers, thinner lenses, and flatter corneas, and weight is independently related to refraction, although the exact biometric component responsible for this association is not apparent.
Refractive error in children in a rural population in India.
TLDR
Refractive error was the main cause of visual impairment in children aged between 7 and 15 years in rural India and it is important that effective strategies be developed to eliminate this easily treated cause ofVisual impairment.
Refractive Error Study in Children: results from Mechi Zone, Nepal.
TLDR
The prevalence of reduced vision is very low in school-age children in Nepal, most of it because of correctable refractive error, and the prevalence of myopia is higher for more recent birth cohorts.

TLDR
Myopia can progress after the age of puberty, but at a slower rate than during childhood, and axial elongation of the eyeball is the main component that changes in myopic progression.

TLDR
Reduced vision because of uncorrected refractive error is a major public health problem in urban school-aged children in India and cost-effective strategies are needed to eliminate this easily treated cause of vision impairment.
