[Anomalies of refraction and optimal correction of ametropia in workers in the metallurgy industry]. 1989

E K Mambetov, and M K Shakenova

The state of refraction has been studied in workers of main shops of the Karaganda combined metallurgical plant, and methods for correction of the revealed ametropies determined. Anomalies of refraction were revealed in 39.5% of cases of the whole number of the subjects, and most frequently in workers of sheet-rolling and tin shops (52%). Myopia of various degree was recorded in 19.6%, hypermetropia--in 11.3%, astigmatism--in 3.1%, anisometropia--in 5.3% of cases. The obtained ergographic data base shows that correct ametropic correction in workers of metallurgical industry improves visual capability to work. The workers of metallurgical industry with anomalies of refraction were prescribed spectacle or contact lens correction; spectacles with fixing devices were used. Optimal correction of ametropia may be regarded as ophthalmoergonomic measure, being of great importance for improving visual capability to work in metallurgists.
