Visual Hazards Associated With Using Computers

The aim of the study was to determine the hazards associated with using computers. A survey of 100 computer users working in business centers in Ilorin, Kwara State was done. Some of the visual hazards noted included; headache, eye redness, eye ache, double (blurred) vision, diminishing vision, eye watering and eye itching (irritation). 58% of the computer users had at least one visual hazard in this investigation. There was no correlation between viewing distance and visual hazards. Screen filter was shown to have minimal effect in reducing visual problems according to this study. Visual hazards were significantly related to the age of the operator and increase in hours spent on the computer per day was shown to be proportional to the occurrence of visual hazards.Keywords; Visual hazards, Video terminal display, between two distinct points at a particular distance.
