Good eyesight does not make good vision! Did you know you can pass every eye exam and still have serious issues with functional vision processing?
A standard eye exam checks your eyes’ physical health and ability to focus on stationary objects, but it does not measure critical dynamic functional vision processing skills such as the eyes’ movement and coordination. 20/20 vision is only ONE of more than 17 important functional vision skills required to perform well in school or sports.
Functional vision processing is how your entire visual neural system. It is how your eyes and brain move through, learn, and interact with your surroundings, i.e., classroom, home, world, sport venue.
Definition of Functional Vision Processing
Both your eyes and brain must work together for you to navigate the world. It is this connection that makes up your functional vision processing. Functional vision processing is the ability to:
- To follow a moving object without moving your head
- To track an object in the vertical and horizontal, diagonal, and circular planes
- To track across the midline of the eyes with smooth pursuit of the object
Functional vision processing requires coordination between different visual skills that include the following:
Visual Fixation. The ability to visually attend to a target or object while maintaining focus on the object.
Saccadic Eye Movement. The ability to rapidly and smoothly shift your vision between two objects without turning or moving your head. Visual scanning occurs in vertical and horizontal, and perpendicular movements.
Smooth Pursuit Eye Movement. The ability allows you to easily follow an object as it moves in vertical, horizontal, diagonal, and circular movements.
Convergence. This ability to simultaneously focus both eyes together on an object.
