Studies indicate that 70-90% of what students learn in school is presented visually.
If a student is struggling to read, he/she may lack visual skills to be a successful student. Even though a student may pass the standard school eye screening and have 20/20 vision, the student may suffer from learning - related vision problems. The standard school vision screening is the Snellen Test - the ability for the student to read a standardized size letter at 20 feet. Most students can pass the school screening test which means they can read the blackboard or whiteboard and follow along with the teacher’s instruction. However, passing the Snellen Test does not mean a student has developed visual skills. There are other visual skills that need to be developed in order for a student to be able to read for prolonged periods of time, to constantly look from the board down to a notebook and back to the board while taking notes, and complete learning activities at near point.
A student who is suspected of having a learning-related vision problem, a comprehensive eye exam, completed by a behavioral optometrist, would assess eye functions and eye health. The behavioral optometrist would make any treatment recommendations.
