“…7 Accuracy of the prescription in currently worn spectacles also appears to be an important problem in at least some parts of the world. 9 Because of these and other practical problems with spectacles use and the various pathologic associations with higher degrees of myopia, there has been much interest in pharmacologic [10][11][12][13][14] and refractive [15][16][17][18][19][20] strategies to prevent or slow the progression of myopia in children. Behavioral strategies, often focused on reducing near work or visual activity with a high accommodative demand,arealsobecomingmorepopular.Near work has been reported by some studies to increasetheriskformyopiadevelopmentand progression.…”

To study the associations between near work, outdoor activity, and myopia among children attending secondary school in rural China.Methods: Among a random cluster sample of 1892 children in Xichang, China, subjects with an uncorrected acuity of 6/12 or less in either eye (n=984) and a 25% sample of children with normal vision (n=248) underwent measurement of refractive error. Subjects were administered a questionnaire on parental education, time spent outdoors, and weekly time spent engaged in and preferred working distance for a variety of near-work activities.Results: Among 1232 children with refraction data, 998 (81.0%) completed the near-work survey. Their mean age was 14.6 years (SD, 0.8 years), 55.6% were girls, and 83.1% had myopia of −0.5 diopters or less (more myopia) in both eyes. Time and diopter-hours spent on near activities did not differ between children with and without myopia. In regression models, time spent on near activities and time outdoors were unassociated with myopia, adjusting for age, sex, and parental education.Conclusions: These and other recent results raise some doubts about the association between near work and myopia. Additional efforts to identify other environmental factors associated with myopia risk and that may be amenable to intervention are warranted.

“…[84,91,92] Another large sample size, randomized study done by Horner et al suggested that there were no significant different in the rate of myopia progression between the children who wore SCLs and spectacles. [93] Hard contact lenses have longer history than the SCLs. PMMA (polymethyl methacrylate) hard contact lenses were widely prescribed in the clinic although they have side effects caused by low oxygen permeability.…”

“…[94][95][96] On the other hand, soft contact lenses and rigid gas permeable lenses (RGP) were not shown to be effective in retarding myopia progression either (Figure 1). [95][96][97] In the Contact Lens and Myopia Progression study, subjects were randomized to wear either RGP or soft contact lenses for 3 years. 98 Results showed a statistically significant difference in myopia progression in the RGP vs. soft lens group (−1.56 ± 0.95 D for RGP wearers vs −2.19 ± 0.89 D for the soft lens group, p < 0.001) with most of the treatment effect found in the first year (Figure 1).…”

SummaryMyopia is the most common human eye disorder. With its increasing prevalence and earlier ageof-onset in recent birth cohorts, myopia now affects almost 33% of adult individuals in the United States, and epidemic proportions of 85% to 90% adult individuals in Asian cities. Unlike children in Western populations, where the prevalence of myopia is very low (less than 5%), Asian children have prevalences as high as 29% in 7-year-olds. In addition to the direct economic and social burdens of myopia, associated ocular complications may lead to substantial vision loss. This workshop summarizes the current literature regarding myopia epidemiology, genetics, animal model studies, risk factors, and clinical treatments. Published treatment strategies to retard the progression of myopia in children, such as pharmacologic agents, progressive addition lenses, neural adaptation programs are outlined.Myopia, or near-sightedness, is the state of refraction in which parallel rays of light are brought to focus in front of the retina of a resting eye. 1 It is measured by the spherical power in diopters of the diverging lens needed to focus light onto the retina, which can be expressed as the spherical equivalent (SE), that is, sphere + half negative cylinder. Most commonly used definitions of myopia in epidemiologic studies include SE of at least −0.50D, −0.75D, and −1.0D. 2 Myopia is the most common human eye disorder in the world, affecting 85% to 90% of young adults in some Asian countries such as Singapore and Taiwan,3,4 and between 25% and 50% of older adults in the United States and Europe. [5][6][7] Epidemiological studies in Western populations have collectively shown the prevalence of myopia to be low (<5%) in children aged 8 years or younger. [8][9][10][11][12][13][14] However, studies in Asian children suggest a significantly higher prevalence of myopia, affecting 9% to 15% of preschool children 15,16 and 29% of primary school children in Singapore. 17 A study of 10,000 Taiwanese school children found that the prevalence of myopia was 6% in 6-yearolds, with the prevalence increasing to more than 70% by age of 15 years. 18
