Visual and auditory processing are the processes of recognizing and interpreting information taken in through the senses of sight and sound. A visual processing or perceptual disorder refers to a hindered ability to make sense of information taken in through the eyes. This is different from problems involving sight or sharpness of vision. Difficulties with visual processing affect how visual information is interpreted or processed by the brain. Below is a representation of what text might look like if you had a Learning Related Vision Problem.
The following displays the various ways in which text may appear to someone with reading difficulties and how the text should be seen under normal vision circumstances.
Characteristics of Reading Visual Problems
The following symptoms may indicate that YOU or your CHILD has a VISION PROBLEM:
Red, sore, or itchy eyes.
Jerky eye movements, one eye turns in or out.
Squinting, eye rubbing or excessive blinking.
Blurred or double vision.
Headaches, dizziness or nausea after reading.
Head tilting, closing or blocking one eye when reading.

HAVE YOU HEARD THIS BEFORE?!
"WE WERE TOLD OUR CHILD HAD 20/20 EYESIGHT. THE TEACHER THOUGHT SHE JUST WASN'T TRYING HARD ENOUGH."
An eight year old child passed the 20/20 eye chart test with flying colors yet she saw letters move around on the page, words and letters disappear and print go in and out of focus. When asked if she had ever told her parents or teacher that this was happening, she replied was, "No, I thought books did that to everyone."
Children with learning related vision problems rarely report symptoms. They think everyone sees the same as they do.
Vision is more than 20/20 eyesight. It is a complex process involving over 20 visual abilities and more than 65% of all of the pathways to the brain. Nearly 80% of what a child perceives, comprehends and remembers depends on the efficiency of the visual system.
A child can't learn to read when the words get jumbled up on the page and he/she can't remember or make sense of what was just read.
EVEN THOUGH THIS IS AN EXTENSIVE LIST OF SYMPTOMS, IT DOES NOT COVER ALL THE POSSIBLE COMPLICATIONS ASSOCIATED WITH NEUROLOGICAL PROCESS DIFFICULTIES.
