The test applied to the students of the Agroindustry career of the National University of Chimborazo presents previous visual diseases in: 33.3 % myopia, 5.1 % astigmatism, 0.5 % presbyopia, referring to the use of the computer we have: 54.9 % of 2 to 4 hours, 39 % of 4 to 8 hours and 6.2 % more than 8 hours which can cause visual fatigue. This research aims to determine the level of visual computer syndrome when applying the CVSS 17 test and technostress by applying the NTP 730 test. The reliability of the instruments is 0. 693 good and 0.959 mu and good, and the reliability of 0.916 and 0.931 which is very good respectively. The result of visual fatigue is 29.2% symptomatic and 70.8% asymptomatic. Regarding technostress, 55.4% is low, 35.9% is medium, and 8.7% is high. The conclusions are determined: the existence of visual fatigue determines the presence of ocular and visual symptoms which will cause short-term affections to the organ of sight and referring to technostress there is resistance to the use of technology. The presence of visual fatigue is associated with the tele study due to the high frequency of computer use and other environmental factors, the Covid 19 pandemic is one of the factors that has contributed to the phenomenon under study, so it is necessary to implement preventive measures.
