Computer vision syndrome: a study of knowledge and practices in university students
Summary
Computer vision syndrome (CVS) affects nearly 90% of Malaysian university students, with headaches and eye strain being most common. Prolonged daily computer use significantly increases CVS symptoms.
Area of Science:
- Ophthalmology
- Public Health
- Ergonomics
Background:
- Computer vision syndrome (CVS) is a prevalent condition characterized by eye discomfort due to extended computer usage.
- Understanding the prevalence and contributing factors of CVS is crucial for student well-being.
Purpose of the Study:
- To assess the prevalence of CVS symptoms, computer use knowledge, and practices among Malaysian university students.
- To investigate the association between computer usage patterns and the occurrence of CVS symptoms.
Main Methods:
- A cross-sectional questionnaire survey was conducted among 795 university students (aged 18-25) in Malaysia.
- Data collected included demographics, computer usage duration, symptoms experienced, and preventive measures.
Main Results:
- A high prevalence of 89.9% for CVS symptoms was reported, with headache (19.7%) and eye strain (16.4%) being the most frequent.
- Continuous computer use exceeding 2 hours daily significantly correlated with increased CVS symptoms (p=0.0001).
- Taking breaks to look at distant objects was associated with fewer symptoms (p=0.0008), while radiation filters showed no significant benefit (p=0.6777).
Conclusions:
- Nearly 90% of Malaysian university students experience CVS symptoms, highlighting a significant public health concern.
- Extended continuous computer use is a primary risk factor for developing CVS symptoms in this population.

Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
