Abstract
The aim of this study was to further evaluate possible effects of lighting conditions on the spontaneous eyeblink rate (SEBR) of normal young adult human subjects.
A baseline 5 min video recording was made followed by a second recording under test conditions in 7 different groups of 10 subjects. These test conditions were a simple repeat recording under reference conditions (subjects maintaining silence, with gaze directed towards a target on a 2 m distant whiteboard with the luminance of the reflected light of 35 cd/m2, recording under lower (5 cd/m2), higher (75 cd/m2) and floodlit (150 cd/m2) levels, after pupil dilation with phenylephrine 2.5 %, after sudden increase with floodlights (to 200 cd/m2), as compared subjects engaged in conversation.
