Abstract
The effect of indoor air temperature, relative humidity, velocity and pollution on occupants’
eye blink frequency (BF) was examined. In total sixty subjects participated in eight 4 hour
experiments without and with facially applied air movement under individual control of the
subjects. Air movement of either polluted room air supplied isothermally or clean and cool air
was used. Eye blinking video record for the last 15 min of each exposure were analysed. The
increase of the room air temperature and relative humidity from 23 °C and 40% to 26 °C and
70% or to 28 °C and 70% decreased the BF. At temperature of 26 °C and relative humidity of
70% facially applied flow of polluted room air didn’t have significant impact on BF in
comparison without air movement. The increase of BF due to decrease of temperature and
humidity and increase of velocity may be compensated due to the increase in air cleanness.
