Myopia is the most common human eye disorder in the world, and its public health and economic impact is considerable (Vitale et al. 2006; Zheng et al. 2013). Recently interest in myopia and myopia control has grown within the optometry community. There are a number of possible reasons for this renewed interest, for example, the increasing prevalence of myopia (Pan et al. 2012), knowledge that myopia can be considered a ‘dose-dependent’ risk factor for many sight-threatening ocular diseases (Flitcroft 2012) and a growing body of evidence to suggest that clinical intervention strategies to slow myopic progression are moderately successful (for example, Anstice and Phillips 2011; Chia et al. 2014).
