What it does not show
This was a cross-sectional survey, so it cannot show that poor knowledge causes computer vision syndrome or that education would improve symptoms. The reported questionnaire items were sociodemographic, spectacles use, source of information, and knowledge questions, not clinical eye or symptom outcomes. The study included bank workers in Gondar city who use computers, so it may not apply to other occupations, countries, or people without computer work. The computed sample size was 248, but the paper reports 234 completed questionnaires and does not describe nonrespondents. Several awareness and knowledge comparisons are made in the Discussion, but those are not the primary measured results and may reflect different study populations.
The easy way to misread this
Do not equate having heard about computer vision syndrome with having good knowledge. Among 211 respondents who had heard about computer vision syndrome, 95 had poor knowledge and only 63 had good knowledge.
