“…Similar findings were found in a study on 300 medical students in Riyadh, Saudi Arabia, which showed a high percentage of subjects experiencing the symptoms of CVS. In that study, 38% of the subjects experienced more severe symptoms, and 48% experienced symptoms with a higher frequency during the COVID-19 pandemic than before 23 . Therefore, preventive measures should address this issue and prevent CVS from persisting or worsening.…”

Background: During the COVID-19 pandemic, there is an increased risk of computer vision syndrome (CVS), a group of eye and vision-related symptoms due to prolonged digital device use. The study on the prevalence of micronutrient intake deficiencies among Indonesia's adult population in 2018 found micronutrient deficiencies which are essential in eye structure and physiology. Objectives: to determine whether a lack of micronutrient intake contributes to the incidence of CVS among students. Methods: The study used a cross-sectional design. The data were taken online from 34 Nutrition Science Study Program students of Universitas Pembangunan Nasional “Veteran” Jakarta. Data were taken using four repeated 24-hour food recalls and questionnaires. Diagnosis of CVS using the Computer Vision Syndrome Questionnaire, which consists of 16 questions about the frequency and intensity of each symptom. Micronutrient intake was analyzed using the Nutrisurvey 2007 application. Univariate analysis was conducted to describe the characteristics of the variables. An unpaired t-test or Mann-Whitney test was used to test the hypothesis of the difference in micronutrient intake between the non-CVS group and the CVS group. Results: 22 of 34 (64.7%) subjects had CVS, and most of the subjects lacked micronutrient intake. There were no differences in subject characteristics and behavior of computer use between the CVS group and the non-CVS group (p > 0.05). The two groups did not differ in Fe, Mg, Cu, Vitamin E, Vitamin A, Retinol, Vitamin C, and Omega 3 intake (p > 0.05). However, the unpaired t-test showed a significant difference in Zn intake between the two groups (p = 0.036; CI = 0.125-2.716). Conclusions: Zn intake is essential in preventing CVS. Further research is needed on the benefits of Zn to prevent CVS.

“…They showed that risk factors for three or more CVS symptoms were common among students who used electronic devices for longer periods of time (6.8 hours ±2.8) during COVID-19. The longer the duration of use of the aforementioned devices, the more severe and frequent the symptoms [3].…”

“…The most common symptoms of CVS are eye fatigue, headache, blurred vision, dry eyes and neck and shoulder pain. In addition, improper lighting, inadequate viewing distance and poor sitting posture can aggravate and worsen these symptoms [3].…”

Introduction. The COVID-19 pandemic has forced the introduction of remote learning and working. Symptoms of digital eye fatigue are increasingly reducing the quality of life. The aim of the study was to collect opinions on the impact of studying/working remotely on vision impairment and to find out the eye hygiene methods used by the respondents. Material and methods. An original questionnaire consisting of 20 closed-ended questions was used for the study. The form was filled out by 194 people aged 18-55 years (mean: 23.15 ± 6.91 years) who were studying or working at least partially remotely. Results. Respondents working remotely were most likely to spend more than 8 hours a day in front of the computer (49.02%), those working hybrid most often marked 5-6 hours (38.04%). Less than half - 44.85% - had a subjective feeling that their eyesight had deteriorated since they started learning/working remotely, and 19.07% declared that the deterioration of their eyesight had been confirmed by an examination with a specialist. Since starting to study/work online, respondents most often complained of eye fatigue (52.58%), dry eyes (34.54%), and sore/burning eyeballs (25.78%). Among eye hygiene rules, the largest percentage declared using a matte screen (48.97%), using "night mode" on an electronic device after dark (51.55%), sleeping for 7-9 hours (45.36%), and taking a break from the screen by blinking (41.24%). Few people are familiar with and use the exercise of closing and shading their eyes (6.70%) the 20-20-20 rule (4.12%), and do not use a smartphone/computer immediately before bed (2.58%). Conclusions. Most of the respondents stated subjectively, or confirmed by a specialist, that their eyesight had deteriorated, and they associate this with learning/working remotely. The most common ocular symptom in the surveyed group was eye fatigue. There is a large deficit in the knowledge and application of eye hygiene principles that can benefit the organ of vision.
