Data were collected on refraction in three isolated communities in western Newfoundland. Altogether 971 persons, about 80% of the population, were refracted. Subjects were not visually selected. Females showed a greater range of refractions than males at most ages, generally had more negative refractions than males, in particular at younger ages, and showed negative age group means earlier than males. Persons under 30 had more negative mean refractions, and more formal education than persons over 30. The age distribution of refraction in this population is compared with that reported by several others, and arguments presented that exposure to formal education is associated with increased myopia.
在纽芬兰西部的三个孤立社区收集了屈光数据。总共对971人（约占人口的80%）进行了验光。受试者未经过视力筛选。在大多数年龄段，女性的屈光范围比男性更大，总体上比男性有更多的近视屈光，尤其是在较年轻的年龄段，并且比男性更早出现负年龄组均值。30岁以下的人比30岁以上的人有更多的近视平均屈光度数和更多的正规教育。将该人群的屈光年龄分布与其他一些人报告的情况进行了比较，并提出正规教育与近视增加有关的观点。
