As parents, we often focus on ensuring our children have "good eyesight," but vision goes far beyond simply seeing clearly. In fact, vision involves a complex network of brain functions that work together to help us interpret, process, and use visual information. Did you know that approximately 80% of the brain is connected to vision? This connection makes vision one of the most critical factors in a child’s ability to learn effectively.
In this blog, we’ll explore how vision influences learning, discuss the roles of over 18 different brain areas in visual processing, and explain why understanding this process is essential for supporting your child’s academic success.
What Is Vision and Why Does It Involve So Much of the Brain?
Vision isn’t just about seeing clearly; it’s about how the brain understands and uses visual information to interact with the world. While eyesight refers to the sharpness or clarity of vision, vision encompasses much more. It includes the ability to locate, process, and make sense of what we see, and to integrate that information with other senses to form a cohesive understanding of our surroundings.
Because vision involves processing, understanding, and acting on visual data, it engages a wide range of brain functions, connecting with sensory, motor, cognitive, and emotional areas. This integration requires the cooperation of more than 18 different areas of the brain, each playing a unique role in the vision process.
How Different Brain Areas Support Vision for Learning
Let’s break down some of the major brain functions and regions involved in vision and how they contribute to learning:
1. Visual Cortex
The visual cortex, located in the occipital lobe at the back of the brain, is responsible for receiving and processing visual information. It’s the first stop for data from the eyes and helps us recognize shapes, colors, and motion.
Role in Learning: The visual cortex allows children to identify letters, track lines of text, and recognize visual patterns—skills essential for reading and math.
2. Parietal Lobes
The parietal lobes handle spatial awareness, helping us understand where objects are in space. This area is crucial for depth perception and visual-motor coordination.
Role in Learning: Spatial awareness is critical for tasks like copying from the board, writing within lines, and aligning numbers in math problems.
3. Temporal Lobes
The temporal lobes are involved in object recognition and memory association. They help us remember and identify faces, places, and objects, as well as interpret complex visual cues.
Role in Learning: The ability to remember visual information helps children retain what they read and recognize familiar words, concepts, and symbols.
4. Frontal Lobes
The frontal lobes are responsible for higher-level cognitive functions, including planning, decision-making, and attention control. They also play a role in coordinating eye movements.
Role in Learning: Strong frontal lobe function supports attention, impulse control, and sustained focus, which are all critical for effective studying, test-taking, and completing homework.
5. Cerebellum
The cerebellum, often associated with balance and coordination, also plays a role in smooth, coordinated eye movements and visual-motor integration.
Role in Learning: The cerebellum enables children to track lines of text smoothly and helps with activities requiring hand-eye coordination, like writing, drawing, and sports.
6. Brainstem
The brainstem regulates many involuntary functions, including those involved in eye movement and visual attention. It helps direct our focus toward important stimuli.
Role in Learning: The brainstem supports sustained visual attention, allowing children to stay focused on tasks without constantly looking away.
How Vision Impacts Learning on Multiple Levels
Since vision involves so many brain areas, any imbalance in this system can affect learning in a variety of ways. Here are a few examples of how vision challenges can impact academic success:
1. Reading Comprehension and Focus
Children with visual processing issues may struggle with reading comprehension because their brains have difficulty tracking lines of text, coordinating eye movements, or focusing on small print. This can lead to frustration and a lack of confidence in reading skills.
2. Handwriting and Eye-Hand Coordination
Tasks that require precise visual-motor skills, such as handwriting, can be challenging for children with visual-motor coordination issues. These children may struggle to write neatly, align their letters, or copy from the board.
3. Mathematical Skills and Spatial Awareness
Visual-spatial skills are critical for understanding math concepts and organizing numbers on a page. Children with spatial awareness difficulties may have trouble aligning numbers for addition or understanding the spatial relationships between shapes.
4. Sustained Attention and Task Completion
The brain areas involved in vision are also connected to attention regulation. Children with vision challenges may find it difficult to sustain focus on a task, often losing interest or becoming distracted.
5. Social Awareness and Interpretation of Visual Cues
Vision also impacts social skills, as it allows us to interpret facial expressions, body language, and other nonverbal cues. Children who struggle with these visual skills may miss out on important social information, which can lead to social difficulties.
The Importance of a Functional Vision Evaluation
Many standard eye exams only measure eyesight and distance clarity, typically using a Snellen Eye Chart to assess 20/20 vision. However, this type of test doesn’t evaluate how well the visual brain areas work together to support learning.
A Functional Vision Evaluation with a Developmental or Neurocognitive Optometrist goes beyond simple clarity. This type of exam assesses:
How well the eyes work together as a team
The brain’s ability to process visual information efficiently
How visual skills integrate with other areas of development, such as motor coordination and spatial awareness
By understanding your child’s visual strengths and weaknesses, you can identify areas where support may be needed and take steps to improve their learning experience.
How Therapeutic Lenses and Vision Therapy Can Help
If a Functional Vision Evaluation identifies challenges in your child’s ability to control their eyes and understand their vision, Therapeutic Lenses may be recommended to help remove as many stressors as possible. If there are visual “lessons” that were not learned during development, lenses alone will not help for long-term resolution, and Vision Therapy may be recommended. Vision Therapy is a specialized program designed to strengthen the connections between the eyes and brain, helping children improve their visual skills in a targeted, structured way.
Through Vision Therapy, children learn exercises that help develop:
Smooth and coordinated eye movements
Improved focus and sustained attention
Enhanced visual-spatial skills and eye-hand coordination
Greater visual memory and recall
These skills not only support academic performance but also contribute to better confidence and overall quality of life.
Supporting Your Child’s Learning Journey
Understanding that vision is more than just eyesight opens up new possibilities for supporting your child’s academic success. With over 18 brain areas at work, vision is a complex and integral part of learning. When these areas function smoothly together at an automatic level, children are better able to focus, understand, and engage with their schoolwork.
If you suspect that vision challenges may be affecting your child’s learning, consider scheduling a Functional Vision Evaluation. At Arizona Vision Therapy Center, we specialize in identifying and treating vision problems that impact learning, using Therapeutic Lenses and Vision Therapy to help children develop the visual skills they need to thrive.
