The aim was to assess prevalence of computer vision syndrome and find association of various factors with occurrence of symptoms. Methods- In this cross-sectional study participant were surveyed using self administered questionnaire and underwent complete ophthalmological and dry eye assessment. Results- A total of 150 participants aged 18-40 years were examined. Majority of the patients were in the age group of 26-30 years, who accounted for 57 cases i.e. 38% of total cases. Male and Female sex distribution was unequal in this study. Males 81 (54%) and females 69 (46%). The prevalence of symptoms of CVS was found to be 75.33% (113/150); most disturbing symptom was headache 101/150 (67.33%), tired eyes 76(50.66%) ,pain behind eyes 74(49.33%) Majority of patients 97 (64.66%) used computer for 4-6 hours. Abnormal TBUT 56 (37.4%), Schirmer’s Test II 42 (28%), Tear height meniscus 59 (39.4%), fluroscein staining findings 15 (10%), lissamine green staining findings 20 (13.33%) and conjunctival impression cytology findings were reported as mild dysplasia in 25 (16.66%), moderate dysplasia 7(4.66%), severe dysplasia 3 (2%), acute inflammatory lesions 5 (3.33%) & inclusion of Chlamydia trachomatis body was seen in 1. Knowledge about CVS was present in 65(43.33%). Conclusion- Most participants had CVS and its severity was correlated with prolonged working hours on computer. There was marked unawareness about CVS. Keywords- Computer vision syndrome, conjunctival impression cytology, fluroscein staining, lissamine green staining, tear film break up time, Schirmer’s test. 1. Loh KY, Reddy SC.
