To assess the feasibility of providing a stock of ready made spectacles for correction of refractive error in the general population.
Data were collected in the Visual Impairment Project, a population based survey of Victorian residents aged 40 years or older in randomly selected urban and rural sample areas. This included a refractive eye examination and the proportion of subjects with hypermetropia, emmetropia (defined as -1.0 to +1.0D spherical equivalent), and myopia documented in the 40-60 year age group.
2595 (54.8%) participants were aged between 40 and 60 years. Those with a best corrected visual acuity of less than 6/12, astigmatism of more than 1.25D, and anisometropia of more than 0.5D were excluded. 516 participants had refractive error which was deemed suitable for correction by "off the shelf" spectacles. This represents 19.9% of all participants between 40 and 60 years of age. Provision of spectacles in 0.5D increments would provide suitable stock spectacles for 85.5% of a -3.0 to +3.0D range or 89.2% of a -3.50 to +3.50D range.
Ready made "off the shelf" spectacles could significantly alleviate visual morbidity due to refractive error in up to 20% of an urban population in Australia. This approach may also be useful in developing countries with poor access to optometric services.
评估为普通人群提供成品眼镜以矫正屈光不正的可行性。
数据收集于视力损害项目，该项目是对维多利亚州40岁及以上居民在随机选取的城乡样本区域进行的基于人群的调查。这包括一次眼部屈光检查以及40 - 60岁年龄组中记录的远视、正视（定义为等效球镜度数在 -1.0至 +1.0D之间）和近视患者的比例。
2595名（54.8%）参与者年龄在40至60岁之间。最佳矫正视力低于6/12、散光超过1.25D以及屈光参差超过0.5D的参与者被排除。516名参与者的屈光不正被认为适合用“现成的”眼镜矫正。这占40至60岁所有参与者的19.9%。以0.5D的增量提供眼镜可为 -3.0至 +3.0D范围的85.5%或 -3.50至 +3.50D范围的89.2%提供合适的库存眼镜。
现成的“现成可用”眼镜可显著减轻澳大利亚城市人口中高达20%因屈光不正导致的视力损害。这种方法在难以获得验光服务的发展中国家可能也有用。
