Correlation between Binocular Vision and CVSS-17 Questionnaire in Taiwan High-Tech Industry Engineers

Purpose: To analyze the relationship between binocular visual function and visual-related symptoms in the high-tech industry group. Methods The study sample was comprised of 33 participants aged between 20 and 40 years. After completing basic information and the CVSS-17 questionnaire, the participants underwent a comprehensive examination of binocular visual function. All data were statistically analyzed with SPSS V26.0 software. Results The value of the binocular vision function of the Taiwan high-tech industry group was significantly different compared with the Scheiman & Morgan standard value. Similar results were shown in the Taiwan binocular visual function standard study, which was conducted during 2020. Study subjects were generally found to exhibit larger exophoric at distance, which in turn might lead to a lower ability to maintain binocular fusion to a single image, or recover from fusional disruption at distance. Subjects also experienced accommodation and convergence problems at near at the same time. Only the daily computer use time had a significant impact on the CVSS17 scores, particularly for internal symptom factor (ISF) dimensions. The interaction between the ISF and external symptom factor (ESF) resulted in more severe visual symptoms in patients. Conclusion No research has demonstrated a relationship between dry eye and computer vision syndrome in high-tech industry professionals, specifically regarding binocular vision. This lack of evidence serves as the primary motivation for conducting this study.
