It has been reported that children with myopia spent significantly more time reading than non-myopic children who spent more time playing outdoors. Socioeconomic status and higher levels of education have also The word "ametropia" can be used interchangeably with "refractive error". Prevalence of myopia in local and international schools in Hong Kong. This effect was consistent across all ethnic groups. Source
To the best of our knowledge, this is the first prospective study that has demonstrated an association between maternal reproductive age and myopic refractive change. A longitudinal cohort study. All models were fitted with the MIXED procedure (SAS, ver. 9.2; SAS Institute, Cary, NC). Subjects' average RPR was not related to the rate of axial elongation (P = 0.77) nor was a more hyperopic RPR at the start of a 1-year interval (P = 0.22). http://www.aaopt.org/one-year-follow-refractive-error-progression-and-ocular-components-changes-college-students-daejeon
Interestingly, children with older maternal age (>35 years) were 4.0 (95% CI 1.3–11.9) times more likely to have aniso-astigmatism per the Sydney Myopia Study. Cylindrical power glasses are prescribed for significant astigmatism, which, if not corrected, can lead to suboptimal adult vision. All participants (children and their parents) signed written informed assent/consent.

Conclusions In this cohort, children with older maternal reproductive age had more myopic refractive change. Axial length was measured by A-scan ultrasonography. National Institutes of Health. 79 (4): 301–320. View Article PubMed/NCBI Google Scholar 18.

In the design of cost-effective programs for the periodic screening and treatment of uncorrected refractive error, children initially found to require refractive correction should be targeted for relatively frequent rescreening, as http://www.sciencedirect.com/science/article/pii/S0002939402016896 View Article PubMed/NCBI Google Scholar 33.

The cumulative incidence of myopia, defined as a spherical equivalent refractive error of -0.50 diopters or more in either eye, among initial emmetropes and hyperopes was 14.1% (95% confidence interval [CI], Furthermore, studies have reported lack of a relationship between myopia and either prematurity or low birth weight in kindergarten children born without retinopathy of prematurity or in adult twins[33–35]. have a peek here Zadnik, None References 1.
