Abstract
This study was conducted to examine the use of computers among university students, their sense of physical fatigue, and problems arising from watching the screen, as well as discuss the relationship between their fatigue and screen-related problems. The following results were obtained: Information technology-related and male students spent more time per day on average using computers than those in other departments and females. As many as 92.6% of the subjects stated that they felt tired while using computers. The most common symptoms included "eye soreness", "eye fatigue" and "stiff shoulders". In students of other departments, a relationship was noted between these symptoms and the time spent using computers. The screen interface, colors of characters and backgrounds, and other screen-related factors were also associated with their sense of physical fatigue. In developing educational materials and contents for computer learning, it is important to enhance screen usability to help students achieve desired learning effects while preventing eye fatigue as much as possible.
