Concerning visual fatigue, results on BR indicated that reading
under high screen luminance leads to a decrease in the frequency
of blinks with respect to low screen luminance. This result is in line
with a large number of studies (for a review see Rosenfield, 2011)
wherein higher levels of light intensity are usually associated with
a decreased frequency of blinking and an increased rate of tear
evaporation, each of which contributes to dry eyes, one of the main
factors for visual fatigue (Benedetto et al., 2013). Results on VFS
revealed that subjective visual fatigue significantly increased after
reading. However, no effects of either luminance or illuminance
were found. This absence of effects is in line with previous studies
that employed this measure for quite similar purposes (e.g.
Buchner & Baumgartner, 2007; Lee et al., 2011). Furthermore, it
