Purpose: An epidemiological study, concerning the prevalence of myopia among the student population (15–18 years old) of Northern Greece, was carried out.
Methods: Specific questionnaires were used in order to collect data on the refractive condition of students.
Results: Myopia prevalence was 36.8% and was found to be more common in females (46.0%) than in males (29.7%). The prevalence increased in students with myopic parents and myopic siblings. It was also found that myopia correlates strongly with nearwork and school performance.
Conclusion: The study results suggest that myopia is a rather common refractive error in Greek students. Findings also indicate that myopia is probably hereditary and correlates with educational level, intelligence and excessive nearwork.
