“…The CVS-Q © has good psychometric properties derived from the Rasch Analysis, with sensitivity and specificity values of 75.0% and 70.2%, respectively. This questionnaire has been used in Spanish workers [20][21][22][23] and its translation, cultural adaptation and validation into different languages are also being carried out. 24 In the absence of CVS studies in European countries, and particularly in Spain, this study was proposed with the aim of estimating the prevalence of CVS in a sample of Spanish university population and determining its relationship with sociodemographic and optical correction factors and exposure to digital devices.…”

Aim To estimate the prevalence of computer vision syndrome (CVS) in university students and its relationship with sociodemographic and optical correction factors and exposure to video display terminal (VDT). Methods This cross‐sectional study included 244 Spanish university students who responded to an anamnesis, a VDT exposure questionnaire and the Computer Vision Syndrome Questionnaire (CVS‐Q©). A descriptive analysis was performed and the prevalence of CVS was calculated. Logistic regression models were used to measure the association between CVS and the variables studied. Results The mean age was 20.7 years (SD = 2.1), 57% were women, 78.3% used VDTs ≥ 2 hours/day to study. The prevalence of CVS was 76.6%, and the most frequent symptoms were headache and itching. In the crude analysis, being a woman, using glasses daily and to study, and a longer VDT use to study and in total were associated with a higher prevalence of CVS; while in the older group, the prevalence was lower. In the multivariate model, VDT use to study was associated with a greater probability of CVS (aOR: 3.43; 95%CI: 1.03‐11.42), and being between 22 and 29 years was associated with a lower probability of it (aOR: 0.36; 95%CI: 0.15‐0.89). Conclusion CVS has a high prevalence amongst Spanish university students. The most affected are the younger ones and those who use VDTs for longer hours to study. It is essential to continue investigating the influence of the type of tasks conducted with VDTs on CVS and thus to establish the preventive measures to reduce this syndrome.

“…The majority of the students in the current study used DD for more than six hours per day, which has been shown to be one of the risk factors of developing CVS [ 16 - 18 ], especially in contact lens users [ 11 ]. It is of interest to note that a higher percentage of students in this study use DDs for more than six hours compared to students in the region [ 2 , 12 ].…”

Background: Several ocular and visual symptoms resulting from use of digital devices are collectively known as digital eye strain (DES) or computer vision syndrome (CVS). Few studies exist on the prevalence of DES among young adults in the Eastern Mediterranean region. Objectives: This study aimed to investigate the prevalence and severity of digital eye strain among a university student population in Jordan. Methods: A cross-sectional study was conducted with students enrolled at Al-Ahliyya Amman University in Jordan. DES was evaluated using the Computer Vision Syndrome Questionnaire (CVS-Q), which was filled out by students who were approached at random and signed an informed consent to participate in the study. Information related to the type, intensity of usage, settings of digital device (DD) used, and post-device use student-reported physical complaints were recorded. Results: Data from 382 students were analyzed. Prevalence of CVS was 94.5%, with tearing being the most prevalent symptom (59%), while double vision was least reported by students (18.3%). DD use for more than six hours per day was reported by 55.5% of the sample size, and 30.7% of the students reported pain in joints of fingers and wrists after using a mobile phone. Conclusion: CVS is highly prevalent among university students in Jordan. With the increased dependence on online education due to coronavirus disease, safe habits in digital device use are recommended.

“…Eye symptoms increased with duration of VDU use, and markedly increased with more than six hours of screen use ( P = 0.01). Computer use has increased in healthcare with the growing use of electronic medical records; healthcare workers may experience a high prevalence of computer vision syndrome, with symptoms corresponding to increased screen time 20 .…”

Use of ambient lighting during colonoscopy and its effect on adenoma detection rate and eye fatigue: results of a pilot study

et al. 2021

View full text Add to dashboard Cite

Background and study aims Adenoma detection rate (ADR) appears to decrease as the number of consecutive hours performing procedures increases, and eye strain may be a contributing factor. Ambient light may improve symptoms of eye strain, but its effects have yet to be explored in the field of gastroenterology. We aim to determine if using ambient lighting during screening colonoscopy will maintain ADRs and improve eye strain symptoms compared with low lighting. Methods At a single center, retrospective data were collected on colonoscopies performed under low lighting and compared to prospective data collected on colonoscopies with ambient lighting. Eye fatigue surveys were completed by gastroenterologists. Satisfaction surveys were completed by physicians and staff. Results Of 498 low light and 611 ambient light cases, 172 and 220 adenomas were detected, respectively (P = 0.611). Under low lighting, the ADR decreased 5.6 % from first to last case of the day (P = 0.2658). With ambient lighting, the ADR increased by 2.80 % (P = 0.5445). The difference in the overall change in ADR between first and last cases with ambient light versus low light was statistically significant (8.40 % total unit change, P = 0.01). The average eye strain scores were 8.12 with low light, and 5.63 with ambient light (P = 0.3341). Conclusions Performing screening colonoscopies with ambient light may improve the differential change in ADR that occurs from the beginning to the end of the day. This improvement in ADR may be related to improvement in operator fatigue. The effect of ambient light on eye strain is unclear. Further investigation is warranted on the impact of ambient light on symptoms of eye strain and ADR.
