Abstract


Prolonged computer use has been reported to be associated with elevated intraocular pressure
(IOP) and an increased risk of Computer Vision Syndrome (CVS). However, this issue has been one of
controversy. This study aimed to preliminarily investigate the effect of using a laptop computer and tablet
computer in terms of changes to IOP in healthy adult participants. Ten healthy participants (aged 27.6 (6.4)
years, ranging 21-39 years; male: female = 2:8) participated and were randomly assigned to either the laptop
computer user or the tablet computer user group. Each subject was requested to work on either a laptop or
tablet for 60 minutes. The IOP was subsequently measured via a non-contact tonometer in both eyes at 15, 30,
45, and 60-minute intervals. Pre-intervention IOP and IOP changes were compared within and between
groups. The results showed that mean IOP at each interval was not significantly different when compared
among pre-intervention at different time points in both eyes. Mean IOP in the laptop computer group was
slightly higher than that of the tablet computer group, yet there was no significant difference. The results of
this study demonstrate that laptop and tablet usage for 60 minutes may not affect IOP levels in healthy
volunteers. Hence, further research involving a larger sample size and longer exposure time to computer
screens is needed
