6.3.2 Sex

Many studies have compared the prevalence of myopia in males and females. Older studies have some tendency to report higher prevalence in males, whereas more recent studies more commonly report higher prevalence in females. For example, the Blue Mountains Eye Study reported that older male adults were more myopic than females [59], but the situation was reversed in the Sydney Myopia Study on children [42, 43, 96, 139]. Similarly, the Liwan Eye Study reported that sex differences in older adults were marginal [140], but in younger cohorts, girls were more likely to be myopic than boys [141]. The massive difference between the prevalence of myopia in girls and boys in Orthodox Jewish communities in Israel, where the boys undergo very intensive education from an early age, provides an extreme inverted example of this trend [78]. This variability does not suggest a direct biological link between sex and myopia, but rather suggests that the links may be mediated by social factors such as access to education for girls, which have changed considerably in many places in recent decades.
