“…1 Moreover, high myopia is associated with other progressive eye disabilities including retinal detachment, glaucoma, cataract, optic disk changes, and maculopathy. 2,3 As such, uncorrected myopia has an enormous impact on society in relation to education and the economy. 4,5 The prevalence of myopia varies widely according to the region in the world, such that relatively low prevalence was reported in Africa, whereas higher prevalence was reported in Asia.…”

Purpose: To assess the prevalence of myopia and associated factors among secondary school children in a rural area of Vietnam. Methods: A school-based cross-sectional study of children in grades six to nine was conducted in four secondary schools in Hoang Mai town, Nghe An Province, Vietnam, during December 2018 and January 2019. The status of myopia was defined as a spherical equivalent objective refractive error of −0.50 D or worse in either eye. A case-control study was conducted to explore factors associated with myopia, where children with myopia were considered to be cases, and children without myopia were considered to be controls. Factors associated with myopia were analyzed using univariate and multivariate logistic regression. Results: The prevalence of myopia among secondary school children was 14.2% (95% CI: 12.7-15.7%) and tended to increase with grade, from 10.5% in grade six to 17.7% in grade nine. Myopia prevalence in girls was significantly higher than in boys. Factors associated with myopia were a mother with a college/university education (OR = 2.5, 95% CI = 1.2-5.3), parents who wore spectacles (OR = 2.0, 95% CI = 1.1-3.8), distance from near work (OR = 5.2, 95% CI = 3.5-7.9), and taking breaks after 30 minutes of continued reading (OR = 1.6, 95% CI = 1.1-2.5). However, there were inverse associations with myopia for children belonging to the wealthiest households (OR = 0.2, 95% CI = 0.1-0.5) and time spent performing outdoor activities (OR = 0.6, 95% CI = 0.4-0.9). Conclusion: Our study showed that the prevalence of myopia is considerable among secondary children in rural areas of Vietnam. The prevalence of myopia tended to increase among children in higher grade levels. Thus, appropriate interventions should be developed and conducted to deal with the issue of school-age myopia.

“…The rate of myopia incidence in young people is growing faster than ever and presents an unmet clinical need along with heightened costs [45,46] Now, however, there is increasing interest in the use of contact lenses for the control of myopia but brings with it added challenges in the regulatory field [48][49][50][51][52]. These include orthokeratology lenses, soft multifocal lenses and soft daily lens, as per the Cooper Vision website, who to the authors' understanding, have the only EU CE approval marked contact lens for a myopia control indication (MiSight®).…”

“…Currently, there are several publications from animal and human studies showing that myopic defocus (MD) retards eye growth and myopia progression, while hyperopic defocus promotes eye growth compared with SV spectacle lenses [9][10][11][12]. In clinical, there are two major spectacle lenses designs based on the idea of MD: defocus incorporated multiple segments (DIMS) lenses and Apollo progressive addition lenses (PALs) (Apollo Eyewear, River Grove, IL, USA) [10,13,14].…”

Background: Myopia is increasing in prevalence and is currently recognized as a significant public health issue worldwide, particularly in China. Once myopia develops, appropriate clinical interventions need to be prescribed to slow its progression. Currently, several publications indicate that myopic defocus (MD) retards eye growth and myopia progression. However, no clinical trials have compared the outcomes of different MD spectacle lenses in the same observational group, especially in mainland China. The aim of the present study is to compare the myopia control efficiency of two different MD spectacle lenses: defocus incorporated multiple segments (DIMS) lenses and Apollo progressive addition lenses (PALs). Methods: The trial is designed as a 3-year, prospective, randomized, multicenter clinical trial of schoolchildren treated with DIMS lenses and PALs. A total of 600 Chinese primary school children aged 6-12 years will be recruited, and each group is intended to include 300 subjects. The inclusion criteria are myopia between − 1.00 and − 5.00 diopters and astigmatism ≤ 1.50 diopters. The follow-up time points will be 1 month (m), 3 m, 6 m, 12 m, 18 m, 24 m, 30 m, and 36 m. The primary outcome will be determined by the difference between the two groups in cycloplegic spherical equivalent refraction between baseline and the last follow-up visit. The secondary outcome is the axial length, and the exploratory outcomes include ocular biometric measures, peripheral refraction, binocular vision, accommodation, compliance, and the results of questionnaires related to wearing experiences.
