Today, children increasingly use these devices both for education and recreation. Millions of children use computers on a daily basis at school and at home. Children can experience many of the same symptoms related to computer use as adults. Extensive viewing of the computer screen can lead to eye discomfort, fatigue, blurred vision and headaches. However, some unique aspects of how children use computers may make them more susceptible than adults to the development of these problems.
Children often have a limited degree of self-awareness.
In some cases, this may cause the eyes to be unable to smoothly and easily focus on a particular object, even long after the original work is completed. Eye irritation may occur because of poor tearflow over the eye due to reduced blinking. Blinking is often inhibited by concentration and staring at a computer or video screen. Compounding this, computers usually are located higher in the field of view than traditional paperowk. This results in the upper eyelids being retracted to a greater extent.
