The documents that recommend different illumination levels to public buildings that rise with the difficulty of the visual task commonly required for using a certain space, considering visual tasks varying from passing through a hall or corridor, to tasks with a medium visual level requirement like detecting, reaching and using objects. Basic research in the field of vision has shown that illumination increases visual acuity (VA) in the VI and affects their subjective comfort, but the levels in lx., varying from 1.5 to 5000 in those studies, strongly differ both in the highest and lowest levels from those used in public buildings.Therefore, it is very difficult to know whether the VA of the visually impaired (VI) it is also modified with the illumination commonly used in these buildings.In order to do so, we developed two experiments oriented to assess both performance and evaluated the subjective impact of illumination levels, using illumination and color temperature levels.The illuminations levels tested were the lowest and highest mean levels founded in the public buildings evaluated.Results show that performance do not statistically differ with the different parameters implemented, showing that the illumination levels and types founded in public buildings do not introduce accessibility problems for the VI, being unnecessary the medium illumination levels recommended.Temperature of color and illumination levels, introduce important differences in the subjective evaluation of public buildings. Thus, subjects considered that accessibility, comfort, impact and control, assessed through an emotional impact scale differ with different illuminations.Our results show a discrepancy between the objective assessment of performance an
