Resumen Results of a survey of 52 assembly workers, aged 17-18, in the watchmaking industry. The parts to be assembled were so minute that these young workers often had to use a magnifying glass (up to 65% of the work shift) for these visual tasks. Mere visual examination of the parts to be assembled caused eye fatigue (particularly of the focussing muscles); this fatique was in relation to the length of time a magnifying glass had to be used. Laboratory tests on young watchmakers assembling watch parts showed that visual scrutiny of parts less than 0.15mm in diameter requires a lighting level of 4,000lx, and that the level should be increased to 5,000lx if a magnifying glass has to be used.
