[Ophthalmopathy caused by precision work of sorters of precious stones].
A total of 440 female workers aged 17 to 50, whose work records ranged from 1 to 29 years, engaged in grading the diamonds by the color, shape, size, and quality (a total of 24 to 33 positions) were examined. A random sample of 110 subjects was singled out; this sample was divided into 2 equal groups with or without asthenopic complaints. The refraction, absolute accommodation volume, and relative accommodation reserves were under study. Comparison of these two groups of workers has shown that subjects with precision ophthalmopathy show a trend to a higher incidence of myopia, reduction of the absolute accommodation volume by 1.6 diopters and of the relative accommodation reserves by 1.3 diopters.
