ABSTRACT
The effect
of caffeine <311 blink rate during conversation was aimed at determining
whether caffeine intake will increase or decrease blink rate during
conversation and if these variations had any gender discrimination. The sample
population of 100 subjects within the age range of 18 and 30 years, without any
significant eye disease were used after screening. Blink rate of subjects were
noted and recorded pre and post consumption of 200mg coffee while the subject
conversed with the researcher. Mean blink rate preconsumption of coffee was
13.2588 blinks/min while the mean blink rate 15 minutes, 30, 45, 75, 90, 105
and 120 minutes post-consumption of coffee was 8.496, 9.36, 9.9693, 10.6202,
11.1897, 11.9908, 12.4093, 12.6017 blinks/min respectively. The results showed
that blink rate decreased by 35.9%, 15 minutes post-consumption of caffeine and
by '29.37%, 24.80%, 19.61%, 15.61, 9.56%, 6.41% and 4.96% for 30 minutes 45,
60, 75, 90, 105, and 120 minutes respectively. In conclusion caffeine decreased
