Computer Vision Syndrome Prevalence Among University Students

Prevalence and Severity of Computer Vision Syndrome Among Medical Students

CVS-F3 questionnaire will be used as an instrument to survey CVS prevalence and severity among medical students

Study Overview

• Status: Completed
• Conditions: Computer Vision Syndrome
• Intervention / Treatment: Behavioral: CVS GROUP

Detailed Description

CVS-F3 is a valid questionnaire that includes 26 questions to be responded by the medical students to detect CVS complains and possible complications. The questionnaire includes questions regarding potential ocular, extra-ocular, musclo-skeletal and neuro-psychatric complains caused by CVS. Complete statistical analysis of the survey data will be done using univariate and multivariate logistic and linear regression analysis.
