Abstract

Computer Vision Syndrome (CVS) is due to the interactions between the ocular defense mechanisms and the screen and/or its environment. CVS affected by glare, distance between eyes and screen, brightness, light intensity in the screen and surrounding, screen contrast, and exposure duration. The symptoms and signs are blurred vision, focusing problems, burning sensation, redness, ocular pain, headache, tears disorders, neck and shoulder pain.
The objective was to determine the ocular manifestations and their relation to some of controllable factors affecting the CVS among the Najran University students attended the ophthalmology clinic 2017 to2019.
Methods: it was descriptive, observational cross-sectional study
Result: The number of the CVS patients was 143; 63% male and 37 % female. The study showed that as the distance between the patient and the screen decreased, the symptoms and signs increase. The symptoms and signs were directly related to the exposure per years but not to daily exposure per hours. Epiphora was the most common symptom (70% of patients). Blurred vision significantly occurred in male than female (p 0.01).
Ocular pain & strain occurred in 64% of the patients. Headache in both sexes is 60% and is significantly related to exposure per years (p 0.05).Burning sensation occurred in 50% and is strongly related to duration per years. Itching and dry eye both occurred in 60% and while itching is strongly related to age groups, dry eye related to the daily exposure.
Conclusion: With the revolution of screens, CVS will increase; more awareness and researches are required.
