keep their place, or that their eyes get tired. In some cases, these complaints may be avoidance behaviors or just symptomatic of task difficulty. However, there may be some cases where RD has a visual component, and such complaints should be carefully evaluated. In terms of reversal errors, it is not believed that children who demonstrate frequent reversals in the first year of reading instruction go on to become poor readers. However, if reversals persist even in the face of systematic instruction, they may be an indication for expert assessment. The current study discovered that approximately 30% of the sample is at risk for reversals, which may be a normal condition for second- and third-grade students. However, if such a problem consistently exists when they become fourth and fifth graders, this would be a strong indicator of a vision-related reading disability. Therefore, teachers, parents, and caregivers should carefully observe these behaviors to detect visual problems. Comprehensive vision screening policy The research findings in the current and previous literature provide evidence that at least a certain percentage of children suffer from RD related to a visual deficit. This study revealed that 3% to 5% of the sample showed problems on visual perception skills. It is possible to mention that a certain group of children who have visual deficits may not be respond to intervention programs that are solely based on linguistic components. The ideal solution is to assess the visual deficits that interfere with reading development through comprehensive "vision screening" checklist that could be simply administered by the classroom teacher. The implementation of comprehensive vision screening, covering visual processing and visual efficiency beyond visual acuity, would yield a score that predict the presence or absence of reading-related visual problems. However, current vision screening for young children is administered insufficiently as well as
