Clinical relevance: This study demonstrates an association between myopia and smartphone data usage. Youths now spend more time participating in near tasks as a result of smartphone usage. This poses an additional risk factor for myopia development/progression and is an important research question in relation to potential myopia management strategies. Background: Children are now exposed to another possible environmental risk factor for myopiasmartphones. This study investigates the amount of time students spend on their smartphones and their patterns of smartphone usage from a myopia perspective. Methods: Primary, secondary and tertiary level students completed a questionnaire exploring patterns of smartphone usage and assessing their attitudes toward potential myopia risk factors. Device-recorded data usage over an extended period was quantified as the primary and objective indicator of phone use. Average daily time spent using a smartphone was also quantified by selfreported estimates. Refractive status was verified by an optometrist. Results: Smartphone ownership among the 418 students invited to participate was over 99-per cent. Average daily smartphone data and time usage was 800.37 ± 1,299.88-MB and 265.16 ± 168.02-minutes respectively. Myopic students used almost double the amount of smartphone data at 1,130.71 ± 1,748.14-MB per day compared to non-myopes at 613.63 ± 902.15-MB (p = 0.001). Smartphone time usage was not significantly different (p = 0.09, 12-per cent higher among myopes). Multinomial logistic regression revealed that myopic refractive error was statistically significantly associated with increasing daily smartphone data usage (odds ratio 1.08, 95% CI 1.03-1.14) as well as increasing age (odds ratio 1.09, 95% CI 1.02-1.17) and number of myopic parents (odds ratio 1.55, 95% CI 1.06-2.3). Seventy-three per cent of students believed that digital technology may adversely affect their eyes. Conclusion:This study demonstrates an association between myopia and smartphone data usage. Given the serious nature of the ocular health risks associated with myopia, our findings indicate that this relationship merits more detailed investigation.

Parental attitudes to myopia were typically nonchalant in relation to health risk. This is of particular concern given the impact parents have on children's behaviour and choices with respect to such risk factors, demonstrating an acute need for societal sensitisation to the public health importance of myopia.

The Myopia Outcome Study of Atropine in Children

With the increasing prevalence of myopia there is growing Background: interest in active myopia control. However, the majority of progressive myopes are still prescribed single vision spectacles. This prospective study aims to elucidate the knowledge and attitudes of optometrists toward myopia control, and thereby identify perceived barriers to the implementation of a risk focussed model of myopia management.A series of four focus group discussions were conducted Methods: involving optometrists in different settings and career stages.The key finding to emerge is a disconnect in myopia control Results: knowledge and practices between academic optometrists, final year optometry students and clinicians in practice. Academic faculty believe the optometry curriculum should provide undergraduates with the clinical skills to practise myopia control, however, although students were knowledgeable in relation to myopia associated risk factors, some students had not yet undertaken any practical form of myopia control in their undergraduate degree. Furthermore, students may not receive hands-on myopia control experience during their supervised practice placement, as the majority of clinicians do not offer myopia control treatments, other than to communicate lifestyle advice to modify risk of myopia progression. Clinicians alluded to a lack of availability of myopia control interventions and identified a range of barriers relating to their training, clinical practice and public health challenges, financial, technological and other constraints that affect the implementation of such interventions. It appears optometrists have to yet embrace myopia control Conclusion:as a core element of the clinical eye care service they provide. Education, training, finance, and time restrictions, as well as limited availability of myopia control therapies were among the main perceived barriers to myopia control. This study revealed a distinct need for alignment between optometric training and the public health need for effective myopia control. Keywords 11,2 1,3

Background: With the increasing prevalence of myopia there is growing interest in active myopia control. However, the majority of progressive myopes are still prescribed single vision spectacles. This prospective study aims to elucidate the knowledge and attitudes of optometrists toward myopia control, and thereby identify perceived barriers to the implementation of a risk focussed model of myopia management. Methods: A series of four focus group discussions were conducted involving optometrists in different settings and career stages. Results: The key finding to emerge is a clear disconnect between academic optometrists, optometry students and clinicians in practice. Academic faculty considered themselves competent in managing progressive myopia and believed the optometry curriculum provides undergraduates with sufficient clinical skills and knowledge to practise myopia control. Final-year optometry students regarded themselves as knowledgeable about myopia control but lack confidence in their ability to practise myopia control, with only one student indicating they would initiate myopia control therapy. The majority of clinicians do not offer myopia control treatments, other than to communicate lifestyle advice to modify risk of myopia progression. Clinicians alluded to a lack of availability of myopia control interventions and identified a range of barriers relating to their training, clinical practice and public health challenges, financial, technological and other constraints that affect the implementation of such interventions. Conclusion: It appears optometrists have to yet embrace myopia control as a core element of the clinical eye care service they provide. Education, training, finance, and time restrictions, as well as limited availability of myopia control therapies were among the main perceived barriers to myopia control. This study revealed a distinct need for alignment between optometric training and the public health need for effective myopia control.
