Background: The visual and refractive status were assessed for grade 7 students in seven governorates in Oman. The health records were reviewed to assess the rationale for their previous school-based vision screening. Methods: A representative sample of 7 th grade students with a refractive error (RE) was examined by optometrists in 2012. Their compliance with spectacle wear was also reviewed. Each student's vision and refractive status in grades 1 and 4 were compared with the status in grade 7. Each student's use of eye care services between grade 4 and 7 was evaluated to determine the uptake of existing eye services for vision problems. Results: This study had 286, 7 th grade students with RE (myopia [94%], hyperopia [4%] and astigmatism [>1D] [2%]). The types of RE between genders in each grade were not significant (P > 0.05). During their vision screening when they were in grade 4, 5 of 13 moderate myopes (>−2D to − 6D) and 3 of 4 high myopes (>−6D) were detected and managed. Ten students with moderate and high myopia were already using spectacles before they were screened in grade 7. The compliance for spectacle wear was 62% in grade 7. Between grades, 4 and 7, 140 (49%) students did not visit eye clinics or an optician. Conclusions: Refractive services in grade 4 were an additional initiative from the eye health care systems in Oman to the actual World Health Organization recommendations of conducting vision screening and RE corrections at grade 7 and 10. However, this was not proved to be significantly effective in early detection, and even the uptake of eye care services by school children was also low.
