Purpose: To compare the prevalence of computer vision syndrome in university students of different teaching modes during the SARS-CoV-2 outbreak period.Methods: A cross-sectional survey study using the validated Computer Vision Syndrome Questionnaire in Chinese medical students of Sichuan University who took classroom lectures and the same-grade foreign students from a Bachelor of Medicine and Bachelor of Surgery (MBBS) program who took online lectures with similar schedules.Results: A total of 137 responses from 63 Chinese students and 74 MBBS students were obtained. The highest frequency of digital screen time was 7-9 h (43.24%, 32/74) for MBBS students and 2-4 h (46.03%, 29/63) for Chinese students. The prevalence of computer vision syndrome among Chinese students and MBBS students were 50.79% and 74.32%, respectively (P = 0.004). The average numbers of reported symptoms were 5.00 ± 2.17 in Chinese students and 5.91 ± 1.90 in MBBS students (P = 0.01). The three most highly reported symptoms were “heavy eyelids” (53.97%), “dryness” (50.79%), and “feeling of a foreign body” (46.03%) in Chinese students and “dryness” (72.97%), “feeling of a foreign body” (62.16%), and “heavy eyelids” (58.11%) in MBBS students. The sum grades of computer vision syndrome had a moderate positive correlation with screen time (Spearman's correlation coefficient = 0.386, P < 0.001). The grades of symptoms of “feeling of a foreign body,” “heavy eyelids,” and “dryness” showed a weak positive correlation with screen time (Spearman's correlation coefficients were 0.220, 0.205, and 0.230, respectively).Conclusion: Online study may contribute to the prevalence of computer vision syndrome among university students.

Introduction: Computer vision syndrome (CVS) is a condition in which a person experiences one or more of eye symptoms as a result of prolonged working on a computer. Objectives: To determine the prevalence of CVS symptoms, knowledge and practices of computer use in students studying in different universities in Malaysia, and to evaluate the association of various factors in computer use with the occurrence of symptoms. Material and methods: In a cross sectional, questionnaire survey study, data was collected in college students regarding the demography, use of spectacles, duration of daily continuous use of computer, symptoms of CVS, preventive measures taken to reduce the symptoms, use of radiation filter on the computer screen, and lighting in the room. Results: A total of 795 students, aged between 18 and 25 years, from five universities in Malaysia were surveyed. The prevalence of symptoms of CVS (one or more) was found to be 89.9%; the most disturbing symptom was headache (19.7%) followed by eye strain (16.4%). Students who used computer for more than 2 hours per day experienced significantly more symptoms of CVS (p=0.0001). Looking at far objects in-between the work was significantly (p=0.0008) associated with less frequency of CVS symptoms. The use of radiation filter on the screen (p=0.6777) did not help in reducing the CVS symptoms. Conclusion: Ninety percent of university students in Malaysia experienced symptoms related to CVS, which was seen more often in those who used computer for more than 2 hours continuously per day.

Study Results

Abstract Background Computer vision syndrome is a multi-factorial condition of the eye that results in symptoms of stress and discomfort among computer users. It causes chronic vision-related morbidity and reduced work productivity. Ninety percent and 75% of computer users globally and in Africa respectively suffer from CVS. It is an insidious chronic condition that however, has hitherto received little attention, both by health providers as well as computer users. Also, it is likely to be under diagnosed as it mimics other eye conditions. The risk factors for CVS include prolonged period of electronic device use and glare. In Kenya, lack of awareness of the disease is a key barrier to early detection, health seeking and use of interventions. The burden of CVS and how much computer users in learning institutions are aware of and perceive CVS remains unknown.Methods This study adopted cross-sectional study design to determine the level of awareness, perception of CVS, uptake of preventive measures by students at Maseno University. In total, we administered questionnaires to 384 randomly selected students.Results The mean age was 19.5 years (SD= 0.747) with 18-24 years as the modal age group. Females comprised 51.3% (n=197) and males 48.7%. Participants who had at least 5 symptoms of CVS were 60.4% (n= 232). Awareness level was classified as low in 47.8%; medium level in 38.2% and high level in 13.8% of respondents . Sixty percent of respondents did not perceive CVS as an issue of public health concern compared to 39.8% who perceived CVS as an issue of public health concern ( p=0.001). In terms of precautionary measures, only duration of computer use (46.2%, p = 0.001 ) were practiced. The study results show that at least 3 out of 5 students have at least five symptoms of CVS, whereas awareness of the disease and related risks remain low.Conclusion The results of the present study indicate that CVS is a less recognized health concern among university students. Consequently, screening for the disease sensitization of students on CVS and awareness campaigns to improve early recognition and diagnosis of disease as well as uptake of interventions is recommended.

Computer Vision Syndrome

Technology has become such an integral part of our life, most of us spend many hours staring at screens today. The digital devices in the form of computers, laptops, i-pads & smartphones etc. are included in day to day lives of everyone. So now a days working adults are not the only ones who are dealing with computer vision syndrome (CVS),even children are affected because of this. Today millions of children use computers & smartphones daily. Too much screen time may cause vision problems for kids.CVS also called digital eye strain. CVS comes under Netrarogas in Ayurveda. Acharya Sushruta & Vagbhata have described about netrarogas in detail in Uttartantra as compared to other Acharyas. So an attempt has made to understand the wisdom of our Acharyas through Ayurvedic classics interpreted by them long ago.

Abstract Background: The public's willingness to be vaccinated will determine the success of the COVID-19 vaccination programme. The aim of this study was to identify acceptance and hesitancy to receive COVID-19 vaccine among university students in Egypt, assess their level of knowledge about COVID-19 vaccine and identify barriers for hesitancy to uptake of COVID-19 vaccine.Methods: This cross-sectional survey study included 1071 university students. A standardized and self-administered questionnaire was constructed by the authors and distributed to university students allover Egypt.Results: Of the 1071 respondents, 739 (69%) were willing to get vaccinated against COVID-19 while 223 (20.8%) reported vaccine hesitancy. Median knowledge score of participants about COVID-19 vaccine was 4 out of 8 (IQR=8). While fear of getting infected (53.6%) and desire to get back to normal life (51%) were the main motives for intention to get vaccinated, fear of serious side effects (100%) and doubting the efficacy of COVID-19 vaccine (60.5%) were the main reasons for vaccine hesitancy and resistance. About 21% of students (n=225) reported voluntary uptake of COVID-19 vaccine. Conclusion: We identified rates of COVID-19 vaccine acceptance and hesitancy and detected poor knowledge scores among university students which may hinder vaccine acceptance. We also detected poor translation of vaccination intention into actual vaccine uptake. Educational campaigns and efforts aiming to raise awareness about safety and efficacy of COVID-19 vaccines need to be directed to this important population.

Background: Computer vision syndrome is a common global problem among millions of computer users including medical students. Medical students are preferring soft copies rather than textbooks. The aim of this study was to assess the knowledge, attitude, and practice of MBBS students about Computer vision syndrome, and to identify its ocular morbidity among them.Methods: A descriptive cross-sectional survey based on the questionnaire was conducted among 1st- 4th-year MBBS students of the Institute of Medicine and 80 students underwent detailed ocular evaluation.Results: A complete survey response was received from 236 students out of 299 students (Response Rate 80%). The mean age of MBBS students was 21.38 years ± 1.328 years and the range were 19-22 years; 76.2% were male and 23.8% were female. The majority (37.2%) spent 2-3 hours/day on the computer and had a higher risk (p-0.0001) of developing Computer vision syndrome. About 69.5% students used a computer at the level of the eye but there was a significant reduction in Computer vision syndrome (p-0.0001) among those who had computer screen below the eye level. Association between taking breaks (p-0.0001) and frequent blinking (p-0.0411) during computer use and relief of symptoms was significant. Only 22.9% had pre-existing knowledge of Computer vision syndrome% and only 25.5% of them were practicing the ideal viewing distance. Among 80 medical students randomly selected for detail eye examinations (63.7% male;36.2% female), the prevalence of Computer vision syndrome was 71.6%. The commonest ocular complaint was a headache (50%) and dry eyes (45%). Myopia was the commonest refractive error (31.2%) and the orthoptic problem was prevalent among 17.5% students.Conclusions: The survey showed that Computer vision syndrome is relevant among MBBS students but the knowledge, attitude, and practice of Computer vision syndrome among them is poor.
