Research indicates that 25% of children are affected by a learning-related vision disorder. In these cases, one or more of a child’s visual systems has a deficiency that is inhibiting their ability to learn and achieve at their highest potential. There are two primary types of visual skills that can be affected: efficiency and processing skills. Efficiency skills are related to the mechanics of how the eyes move, track, team, and focus together. If any of those skills are deficient, then the information being sent to the brain could be incorrect, causing a child to lose their spot when reading, inaccurately perceive depth, or copy the wrong word from the board. Processing skills are related to how the sensory information provided by the eyes is processed in the brain. If one of these skills are deficient, children may not be able to quickly grasp math concepts and number values, spell age-appropriate words correctly, or may reverse or transpose letters or numbers when either reading or writing. All of these skills can be tested by a developmental optometrist, and if deficiencies are found, an individualized course of vision therapy can help bring those skills up to age-appropriate levels, allowing the child to learn and achieve their best.
