Background: The globalization of technology has led to a proliferation of digital devices, encompassing a range of hardware, including computers, screens, tablets, and smartphones. These devices have become integral to modern life, enabling diverse functionalities and applications across various domains . Aim To assess the computer vision syndrome as perceived by the undergraduate nursing students versus clinical teachers. Methods;Design  Cross sectional descriptive survey. Setting study was conducted at the Faculty of Nursing, Tanta University, Egypt. Subjects Two groups of subjects included undergraduate nursing students (350) and all clinical nursing teachers (135). Tools Tool (I): computer and digital devices questionnaire.Tool (II): Computer Vision Symptoms assessment questionnaire. Tool (III): Perception towards computer and digital device Assessment. Results: The  current study revealed computer vision syndrome perception level (55,7%) among nursing students compared to 35.6% of the clinical teachers perception,with high statistical significance difference between the two accompanied by low awareness (28% and 29.6%)of both groups about protective measures of CVS. In despite that students spent more time in front of screens than teachers the CVS prevalence rate for students was 55.3%, compared to a higher rate for teachers, 69.75%.Conclusion: The study concluded that nursing students had poor perception of CVS compared to good perception of the clinical teachers.Recommendations: best practices in CVS interventions such as brain training therapy, program vision exercise and affordable management for treating CVS need to be developed by other researches on variety of large populations, in addition to strengthing the positive perception of CVS among nursing academic staff and students.
