The St. Louis Post-Dispatch (7/27, Sultan) reports, “One in four children in the US have undetected vision problems which could impair learning, according to the American Optometric Association.” Because “approximately 80 percent of learning comes through a child’s eye,” some experts believe that sending children “to school without good vision could be setting them up for failure or even cause them to be misdiagnosed with a learning disability.

Children who need eyeglasses or contact lenses should be examined annually as their vision often changes rapidly as they age.
