Caffeine is a known stimulant that affects nervous system. It is purported that caffeine have the ability to effect visual functions. This research was conducted to assess the influence of caffeinated coffee consumption with intraocular pressure [IOP] and amplitude of accommodation [AA]. Fifty subjects were recruited between the ages of 18 and 29 years. A 240ml of Nescafe Original was given to the subjects to drink. Their age, gender and weight have been recorded for demographic data. The IOP and AA value of subjects were taken at baseline, 30 and 60 minutes after coffee consumption. The findings obtained do not indicate any significant changes with the p value is greater than 0.05. All the changes observed were still within the normal range and result obtained indicated that there was no influence on IOP and AA for both male and female after 60 minutes consumption.
