Knowledge, Attitude and Prevalence of Computer Vision Syndrome in Computer and Smartphone Using Population and Prevention by Ergonomics and Eye Exercises

Abstract

The widespread usage of digital gadgets in close distance has resulted in complex of eye and vision problems collectively called as Computer Vision Syndrome (CVS). It is a major concern in adolescents because they rely on internet and digital platforms for academic purposes in the current pandemic situation. The study focus on the risk factors and ergonomic behaviour that contribute to the development of CVS in students, as well as raising awareness about how to avoid digital eye strain in the future.

Methodology

This cross sectional survey based study was conducted among 203 medical college students. A set of self- administered questionnaire was used to assess the prevalence of CVS symptoms and its associated risk factors. The survey consisted of questions on contact lens and digital screen usage, ergonomics, Computer Vision Syndrome Questionnaire.

Results

The most frequently reported severe CVS symptoms was head ache (11%) followed by tearing (6.9%) in the eyes of the subjects. In addition, 72% of them were had moderate excessive blinking symptoms. 50% of them were have mild headache, 37% of them were have tearing and burning symptoms. In regard to the physical symptoms, 27% of the have neck pain and 12% of them felt neck stiffness.

Conclusion

Finding of the present study revealed that majority of the students have CVS symptoms such as headache followed by dry eyes, tearing and burning sensation. In addition to that, students also reported extra ocular symptoms like neck pain and stiffness more frequently. As colleges continue to improve their educational strategies, it is important to promote student knowledge of the health risks associated with extended computer usage for studying and to explain how to avoid CVS symptoms.
