Resumen |
Visual work capacity changes were noted in 12 students (19-23 years) required to indicate the position of Landolt rings under light produced by incandescent, mercury vapour and fluorescent lamps, at luminance levels of 15 and 135nt (54.3 and 488lx). The findings, which are recapitulated in a table and commented on, show the need to continue research into the causes of low productivity under incandescent lighting, especially at a luminance of 15nt, and the adverse effect of fluorescent or mercury light sources on the perceptive capacities in subjects fatigued by prolonged visual tasks (change in visual perception with time). Further studies should clarify the minimum luminance level for each type of source as a function of the apparent size index of the object observed. |
