Adequate lighting is important for human, especially among workers in laboratories to
perform their task systematically, productively and concurrently in a healthy
environment. The study aims to measure the lighting quality among staffs working in
laboratories with excessive usage of computer and identify the prevalence of computer
vision syndrome symptoms associated with lighting quality. This cross-sectional study
using a purposive sampling method collected data on socio-demography of
participants, their time spent daily on computers and the symptoms of computer vision
syndrome (CVS) using a self-reported questionnaire while the lighting condition was
measured using a lux meter. The results shows that most of the staffs do not working
under appropriate lighting which is below than 300 – 400 lux. A big number of staffs
also experienced one or more symptoms related to computer vision syndrome.
