  • The objective of the study was to assess the prevalence of uncorrected refractive error and its associated factors among school children in Debre Markos District, Ethiopia.

  • Four hundred thirty two students were randomly selected using a multistage stratified sampling technique.

  • Students with visual acuity less than 6/12 had undergone further examination using auto refractor and cross-checked using spherical and cylindrical lenses.

  • Out of 432 students selected for the study, 420 (97.2%) were in the age group 7–15 years. Overall prevalence of refractive error was 43 (10.2%).

  • Myopia was found among the most dominant 5.47% followed by astigmatism 1.9% and hyperopia 1.4% in both sexes.

  • Female sex, higher grade level, and using computers regularly were significantly associated with refractive error.

  • The burden of uncorrected refractive errors is high among primary schools children. Myopia was common in both sexes.

  • The potential risk factors were sex, regular use of computers and higher grade level of students.

  • Hence, school health programs should work on health information dissemination and eye health care services provision.
