When Is Learning Difficulty Due to a Vision Problem?
While learning occurs through a number of complex and interrelated processes, vision plays a key role. Many signs, symptoms, and behaviors associated with learning disabilities are similar to those caused by vision problems. This is why it is so important that a comprehensive vision examination be part of the interdisciplinary evaluation of all children who are failing to succeed in school.
The following chart shows some signs and symptoms to look for that may indicate a vision problem.
||Nearsightedness, Farsightedness, or Astigmatism -inability to see clearly in the distance or up close.|
||Eye coordination problems – inability to coordinate the eyes together effectively.|
||Eye focusing problems – inability to easily refocus eyes or maintain clear focus.|
||Eye tracking problems – inadequate ability to smoothly and accurately move the eyes from one point to another .|
||Faulty visual form perception – inability to discriminate differences in size, shape, or form.|
||Faulty visual memory – inability to remember and understand what is seen.|
||Faulty visual motor integration – inability to process and reproduce visual mages by writing or drawing.|
||Difficulty with laterality and directionality – poor development of left/right awareness.|

How to Identify a Vision Problem
Children should be referred for a comprehensive eye exam whenever visual symptoms are noticed or if they are not achieving their potential. Many of these vision problems will not be detected during a school vision screening or limited vision assessment as part of a school physical or routine pediatric health evaluation.
