- Abstract
Aims and Objectives: To determine the prevalence of Computer Vision Syndrome (CVS) and those Factors associated with it. Methods This was a cross-sectional study conducted at three undergraduate constituent institutes of Khyber Medical University, Peshawar from Aug, 2015-Jan, 2016. Three hundred and five (305) undergraduate students selected through simple random sampling were enrolled in the study. CVS and associated factors were assessed through reliable and valid questionnaire. Statistical package for social sciences (SSPS v 16) was used for data analysis. Chi square test (Fisher exact test wherever necessary) was used to evaluate association between various factors and CVS. A p-value <0.05 was considered statistically significant. Students having squint, wearing glasses and those who were not user of computer were excluded. Results : Of the 305 students enrolled in the final analysis, male: 168 in which 149 (48.8%) positive to CVS and 19 negative and female: 137 in which 127 (46.0%) were positive to CVS and 10 negative were surveyed whom ages were between 18 and 24 years. High prevalence of CVS symptoms (one or more) was observed (90.5%); as shown in figure. Among the underlying factors like type of screen (P< 0.03), use of antiglare screens (p=0.04), taking break (p=0.01), screen distance (P< 0.02), Screen level (P=0.04) all were statistically significant as shown in Table. Upon cross tabulation between CVS and associated symptoms, headache (53.4%) (P< 0.00), dry eyes (P=0.001), watering eyes (P=0.000), redness of eyes (44.9%) (P< 0.00), eye tiredness (60.7%) (P< 0.00), itching (34.8%) (P< 0.00), blurring of vision (34.4%) (P< 0.00) and burning sensation (P= .000) were statistically significant, and were more likely associated with computer use. Conclusion: This study concludes that more than 90% of the students complained of any one of the symptoms of CVS while working on computers. Students were at higher risk of developing CVS, using computer continuously for more hours compared to students who spend fewer hours and took frequent breaks. As the use of computer had become universal, the subject of the prevention of CVS and associated discomfort should be made part of the curriculum with preventive strategies.
