To assess the prevalence of computer vision syndrome/digital eye strain among Filipino radiologists and determine its contributory factors.

Materials and Methods:
This cross-sectional study included all radiology practitioners (residents/fellows-in-training, consultants) who are training or practicing the in the 49 accredited training institution in the Philippines. Measures: An online survey was conducted, which covered five areas: 1) demographic background; 2) workload-related data; 3) appraisal of the radiography workstation and environment; 4) personal eye care; and 5) assessment of digital eye strain symptoms. A total of 16 ocular- and visual-related symptoms from the CVS questionnaire (CVS-Q) described by Seguí et al. were used to assess CVS at the workplace.

There was no statistically significant difference in the prevalence of digital eye strain among participants in terms of most of the demographic and work characteristics assessed. However, the proportion of women versus men with eye strain was 55.21% versus 44.79% (<em>p</em> = 0.02). Those with no refractive errors reported a lower rate of digital eye strain (<em>p</em> = 0.006). Longer duration of breaks contributed to a decrease in CVS symptoms (<em>p</em> = 0.036). Binary logistic regression analysis revealed female sex (odds ratio [OR] = 4.72; 95% confidence interval [CI]: 1.7059 to 13.103) to be an independent predictor of digital eye strain.

Computers and other electronic devices are now almost universally used for a variety of occupational and nonvocational applications. Prolonged computer use can cause a group of symptoms known as CVS or digital eye strain (DES). CVS is a complex of eye and vision related symptoms experienced due to the prolonged use of digital devices Radiologists encounter particular occupational health risks that are distinct from those faced by doctors in other disciplines. At present, majority of diagnostic radiologists’ workload entail lengthy periods of sitting and staring at one or more high-resolution display monitors with high brightness in order to thoroughly analyze radiological pictures and report the findings. By the end of a reading day, there is reduction in the radiologists' accommodation for near vision and ability to focus which impacts their diagnostic ability and can have a big influence on patient care
