title: Myopia, use of eyes, and living habits among men aged 33-37 years.
abstract: As a part of a more extensive research project on health and functional capacity among a representative sample of men, the living habits and backgrounds of myopic men between 33 and 37 years of age living in the town of Jyväskylä were studied in comparison with non-myopic men of the same age. The prevalence of a negative spheric equivalent, which was considered as a criterion of myopia, was 25%. It was found that the myopic, on the average, had been more interested in reading from childhood onwards, their educational and occupational status were higher, and their body structure was lighter. As children they had taken less physical exercise, but as adults no difference was found in physical exercise between the myopic and non-myopic.
