Eye problems are very common in children. The American Optometry Association (AOA) estimates that 1 in 4 children has a vision-related condition. Left untreated, these conditions can have a serious effect on a child’s learning, development, athletic performance, and overall health.Eye problems can also affect physical abilities and athletic performance. Vision irregularities or eye muscle imbalances can affect depth perception, leading to “clumsiness,” tripping, and poor hand-eye coordination.
