To evaluate the effects of reflected glare on eyes, authors assessed the results of annual period health examination for six years and self administrated questionnaire in a semiconductor producing company in Korea. The thirteen workers of lead frame department (LF) worked under the high reflected light to examine the silver plated products. The reference groups were fourteen workers of assembly department worked under the medium reflected light and twelve office workers. All workers of LF complained of getting worse of visual acuity, 81.8% of the workers in the assembly department and 85.7% of office workers respectively. 70 % of LF workers wore the glasses after entering the company, 14.3% of assembly workers, and 40 % of office workers, respectively. Major ophthalmic symptoms were asthenopia, tearing, decreased visual acuity, congestion and dazzled eye. Visual acuity in LF workers was decreased significantly during 5 years (p<0.05) compared with assembly and office workers by examination with the eye test chart (Hahn°¯s Chart).
