Signs and Symptoms of Vision-Based Difficulties

What Symptoms Do Adults and Children Experience
That Result from Issues with Vision?

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 Functional Vision Evaluation be part of the interdisciplinary evaluation of all children who are struggling in school or adults who are experiencing visual issues that may interfere with daily living.

The emphasis is normally on learning difficulties faced by children, but adults are learning new things everyday, on the job and in their personal lives.

Here are some warning signs and symptoms to look for that may indicate a vision problem.

– Trouble writing and remembering letters and numbers?

Possible Vision Problems: Difficulty with laterality and directionality (Poor development of left/right awareness)
Here is a Symptoms Checklist you can use to determine whether you or your child has vision-based learning difficulties.

Physical Signs or Symptoms of a Vision Problem in Children and Adults
Frequent headaches or eye strain
Blurring of distance or near vision, particularly after reading or other close work
Avoidance of close work or other visually demanding tasks
Poor judgment of depth
Turning of an eye in or out, up or down
Tendency to cover or close one eye, or favor the vision in one eye

How to Identify a Vision Problem
Children should be referred for a Functional Vision Evaluation 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.

Please note: In-office therapy under the direction of a behavioral optometrist using prisms, filters and lenses, as used with our patients, is far more effective than home-based therapy.
