Objectives.  This study aimed to evaluate visual display terminal (VDT)-related digital eye strain (ES) and dry eye disease (DED) symptoms in subjects whose work was changed to teleworking (TW) during the coronavirus pandemic.  Methods.  A digital self-reported survey was conducted on subjects in TW, including demographics, medical history, VDT time and ES-related symptoms before and during the pandemic and DED (dry eye questionnaire 5 [DEQ-5] questionnaire).  Results.  A total of 1797 questionnaires were analyzed. Mean age was 40.5 ( SD  11.1) years, and 69.9% were female. The mean number of TW weeks was 10.2 ( SD  3.0). The total VDT total hours increased from 7.4 ( SD  3.3) to 9.5 ( SD  3.3) ( p  &lt; 0.001). All ES symptoms presented a significant increase ( p  &lt; 0.001). The mean DEQ-5 score was 8.3 ( SD  4.9). The oldest group presented lower values, and women had a higher score ( p  &lt; 0.001). Additionally, 28.6% of the subjects were classified with severe DED, and the variables associated with a logistic regression model were total VDT hours, female gender, refractive surgery, rosacea, depression, previous DED, keratoconus and blepharitis.  Conclusions.  The number of VDT hours seemed to be a relevant factor for increase in ES symptoms and a high prevalence of DED during the pandemic period.
