Resumen A yearly ophthalmological examination was performed for two VDT worker groups (workers routinely engaged in both VDT work and key-punch work at a printing company and office people handling VDTs irregularly at a chemical company) and two control groups (typesetters at a printing company and office workers at a chemical company) for three years. All the groups showed lower subjective refractive power in the last than in the first examination; the greatest decrease was found in the routine VDT workers followed by typesetters. Information on naked visual acuities of the routine VDT workers three years before VDT introduction showed that the reduction in visual acuity occurred after VDT introduction. Accommodative powers of workers at the printing company were lower than those of workers at the chemical company, irrespective of VDT work, and the most subjective ophthalmological symptoms were observed in the routine VDT workers. However, no changes of accommodation symptoms were observed between the first and the last examination in any group. VDT work may be associated with the decline in visual acuity of the routine VDT workers, while the key-punch or typesetting work involved more visual burden than the irregular VDT work.
