Computer use and vision-related problems among university students in Ajman, United Arab Emirate

We investigated the independent associations of 3 types of sedentary behavior with depression, anxiety, and sleep quality among 214 Chinese university students. Self-reported sedentary behavior was assessed by the length of time that participants spent on television viewing/computer use, and smartphone use. We used the Self-Rating Depression Scale (SDS) and the Self-Rating Anxiety Scale (SAS) to evaluate depressive status and anxiety symptoms, respectively, and the Pittsburgh Sleep Quality Index (PSQI) to assess sleep quality. The results showed that longer smartphone use was associated with worse SDS, SAS, and PSQI scores. There was no association between the time spent on television viewing and computer use, and depression, anxiety, and poor sleep quality.

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.

The Way

This article examines how the way pro and contra information is distributed between two experts in a written discourse influence readers’ evaluations. One hundred and fifty university students read an expert discussion on the topic of computer use in childhood. Information was presented in either a one-sided (each expert holds one position: pro or contra) or two-sided way (both experts provide pro and contra arguments). Results showed that readers judged experts who communicated more consensus-oriented by taking a two-sided stance to be more trustworthy. Additionally, readers in this group subsequently outlined their own opinion toward the topic more confidently. However, the manipulation did not influence how far readers drew on expert information when formulating a response to a writing task. Implications are drawn for helping readers to process expert discussions and for improving expert communication strategies. It is emphasized that expert discussions provide not only content-focused but also rhetorical challenges.
