Zhao et al 1 assess self-refraction using adjustable-focus spectacles in children aged 5 to 11 years. This concern touches on a number of public health issues, including changing myopia prevalence, clinician shortages, access to adequate vision care, and health equity.Providing an efficient, compact, and mobile means to address vision screening and refractive correction, especially in resource-limited areas, has particular importance for pediatric patients who need simple refractive correction in order to thrive educationally and ultimately in society.Vision impairment poses an enormous global financial burden with associated annual global costs of productivity loss estimated to be $411 billion. According to the World Health Organization (WHO), the 2 leading causes of vision impairment and blindness are uncorrected refractive errors and cataracts. Globally, at least 2.2 billion people have a near or distance vision impairment, and for almost half of these people, vision impairment could have been prevented or has yet to be addressed. 2 Uncorrected refractive errors in young children with early-onset vision impairment can lead to delayed motor, language, emotional, social, and cognitive development with lifelong consequences. School-age children with vision impairment experience lower levels of educational achievement. This can extend into adulthood where vision impairment is associated with lower rates of workforce participation and productivity and higher rates of depression and anxiety.Myopic refractive error is an increasing public health concern. An estimated 80% to 90% of children in East Asian countries and one-third of adults in the US and European countries have myopia. The prevalence of myopia has continued to increase during the past decade, especially in Asian populations. 3 Prior to COVID-19, the WHO predicted that 50% of the world would have myopia by 2050. 2 However, a review 4 of 8 cross-sectional and 2 cohort studies suggested that this may be an underestimation because of reduced time spent outdoors and increased screen time associated with the pandemic. One of the included studies found that the prevalence of myopia increased by about 10% during the pandemic, and another found a mean increase of almost 1 diopter in myopia
