Abstract Details


To evaluate the frequency of eyestrain associated with the computer use in children at school age.


Department of Ophthalmology, General Hospital of Veria, Veria, Greece.


112 pupils (59 boys) with a mean age of 7 years participated in the study. None suffered from any other eye disease except for refractive errors (nearsightedness, farsightedness, astigmatism) corrected with glasses. The average engagement with the computer was 2 hours daily. The presence of symptoms of eyestrain while working on a computer or shortly after, was evaluated by a questionnaire completed by each class teacher.


7% of the pupils reported a feeling of burning or stinging eyes during work on a computer or immediately after. No one reported foreign body sensation. 4% reported feeling of pain, 14% tearing, 36% itchy eyelids, 29% dry eyes, 43% sensitivity to light, and 36% blurred vision. Pupils who reported these symptoms observed a positive correlation between the presence of symptoms and duration of computer use.


The main symptoms of eyestrain related to computer use in order of frequency are the sensitivity to light, blurred vision / itchy eyelids and feeling of dry eye. The positive correlation between the presence of symptoms and duration of computer use is likely to indicate that their presence is associated with the instability of the tear film and the lack of convergence and adaptation that has been reported in computer users after prolonged engagement.
