The incidence and degree of visual defects among computer users were studied in 100 subjects (50 computer users and 50 non computer users). Visual acuity and colour vision tests were conducted using standard Snellen’s chart and Ishihara chart respectively. The visual acuity of computer users showed a significant decrease (P<0.05) when compared to non computer users. The incidence of colour vision is higher among computer users than non computer users. It has also shown that there is a significant difference between subjects with visual defects that use computers and duration of exposure with (P<0.01) when compared to non computer users. Visual defects are correlated to duration of exposure to the use of computers and eye disease. The long use of computers may cause eye strain which lead to visual defects. Keywords: Visual acuity, visual defects, computer users, eye strain, colour vision.
