Refractive errors, if uncorrected, results in an impaired quality of life for millions of people worldwide, irrespective of their age, sex and ethnicity. Over the past decade, a series of studies using a survey methodology, referred to as Refractive Error Study in Children (RESC), were performed in populations with different ethnic origins and cultural settings. These studies confirmed that the prevalence of uncorrected refractive errors is considerably high for children in low-and-middle-income countries. Furthermore, uncorrected refractive error has been noted to have extensive social and economic impacts, such as limiting educational and employment opportunities of economically active persons, healthy individuals and communities. The key public health challenges presented by uncorrected refractive errors, the leading cause of vision impairment ac

By Ecosse Lamoureux Additional author(s): Seang-Mei Saw, Julian Thumboo, Hwee Lin Wee Tin Aung, Paul Mitchell & Tien Y Wong Sponsor/Institution: The Association for Research in Vision and Ophthalmology Publication: Investigative Ophthalmology & Visual Science KEY POINTS The Singapore Malay Eye Study was undertaken to determine the prevalence and impact of vision impairment and major eye diseases in urban Asian populations. Approximately one quarter of Singaporean Malays have myopia. The study shows that although corrected myopia and hyperopia do not affect visual functioning, uncorrected myopia is associated with decreased visual function. As myopia has a negative impact on self-esteem, career choice, and ocular health, interventions that correct myopia could improve participation in daily living and other aspects of Quality of Life in people with uncorrected myopia. Myopia is potentially fully correctable by spectacles or contact lenses. Strategies that inform people of the benefits of proper correction are needed. The long-term benefits of full correction of myopia may include improved visual functioning and Quality of Life. SUMMARY Refractive errors are common eye conditions affecting a large proportion of the adult population, particularly in Asian countries. Myopia, a frequent type of refractive error, appears more prevalent in Asians than in Caucasians. A prevalence of high myopia of 28% and 26.2%, has been recorded in Singaporeans of Chinese and Malay origins, respectively. Persons with myopia remain at risk for conditions caused by excessive axial elongation. Similarly, high myopia is a predisposing factor for retinal detachment, myopic retinopathy, myopic maculopathy, and glaucoma. Uncorrected refractive error is associated with decreased vision-related quality of life and increasing difficulty in performing vision-related tasks. In a recent Australian study, it was shown that myopia corrected with spectacles or contact lenses has a negative impact on some aspects of vision-dependent Quality of Life (QoL). This study was limited, however, by a relatively low prevalence of myopia and a small sample of subjects with myopia. In Asian countries wher
