The Visual System

 

 

What is the visual system?

 

 

The visual system is composed of the eyes and brain and the neurological pathways that connect them. The eyes collect visual information and relay it through the pathways to the brain for interpretation. The visual system plays an integral role in how we process information and is an important factor in how we learn.  In fact, we rely heavily on visual information for many of our physical and mental activities, so the optimal functioning of the visual system is key in enjoying everyday life.

Roughly 30% of the neurons in the brain’s cortex are devoted to vision.

65% of sensory information to the brain is visual

Visual System Issues

 

When the visual system isn’t functioning properly, the brain can miss or misinterpret important information. Underlying issues with the visual system often manifest as learning difficulties in an academic setting, behavioural issues, motor coordination difficulties, or other challenges in everyday life. Sometimes, the issues are uncovered during the developmental years or can result from an injury, such as a concussion.

 

Either way, visual system issues can have a significant impact on daily life, as someone may struggle to learn or perform physical tasks. If these issues are left undiagnosed and untreated, a loss of confidence is often the most devastating result.

 

How are issues with the visual system discovered?

There are several simple screening tests to help determine any issues with the visual system. Testing is worth considering if you experience difficulties learning- especially in reading, writing, and math; if you have had a mild traumatic brain injury or concussion; or if you have trouble with motor coordination.

 

A Mind's Eye™neuro-visual optometrist completes a visual system assessment and can determine which areas may be improved and whether a specific program called Neuro-Visual Training may be beneficial.
