The Developmental Vision Model

Take a look at the illustration below. This represents a DevelopmentalModel of Vision.

The outer circle represents the life activities that are important to your child:
school, work, coordination/sports, play, relationships and success in life.
A strong foundation is required upon which to build. The foundation is
represented as the central core of the concentric circles. This core includes the structural integrity of the vision system; that is, the physical health of the eyes, eyesight, and the visual pathways.

The first concentric circle outside of the core represents visual efficiency; i.e.
how well the eyes fixate (look), follow (track), fuse (coordinate together), and
focus (make objects clear). These visual skills are movement-based.
The second concentric circle out from the core represents visual information
processing (understanding what we see, where things are in space, integration of visual information with other senses, eye-hand-body coordination, visual memory, and visualization).

This Model of Vision represents the basis for the evaluation and treatment
for your child when he is examined by a developmental optometrist. As you
can easily see, there is so much more than 20/20 eyesight to consider. Even if
one eye doctor says your child has 20/20, it doesn’t mean all these other vision skills have been appropriately evaluated. Read more about developmental optometry in the Appendix of my book, See It. Say It. Do It!
