The foundation of all visual processing skills begins with tracking. Since approximately 90% of traumatic brain injuries result in some form of oculomotor dysfunction, mastering this step is essential. During this phase, patients improve visual attention, eye-hand coordination, bimanual integration, and impulse control.
In Month 2, the focus shifts to the parietal lobe, which governs spatial awareness and our understanding of where objects are in relation to ourselves. Efficient parietal lobe functioning allows the brain to better control eye movements for tracking, focusing, and coordination, forming a vital bridge to the next phase.


Flexibility of the eye muscles takes center stage in Month 3. This phase enhances the ability to maintain clarity and alignment when shifting focus between varying distances, such as glancing between a car dashboard and a street sign. Patients gain improved spatial awareness, better concentration, and enhanced ability to integrate peripheral and central vision.
Peripheral awareness is the focus of Month 4, emphasizing the integration of peripheral and central visual information. This skill allows patients to concentrate on what’s directly in front of them while remaining aware of their surroundings—critical for tasks like navigating busy stores without feeling overwhelmed.


In Month 5, the two eyes learn to work as a cohesive team, improving depth perception. By aligning and processing visual input accurately, patients gain a better understanding of dimensions, enhance decision-making abilities for activities like driving, and experience improved stamina for reading and scrolling.
The final month focuses on automaticity, where all previously developed skills come together. Visual tools become second nature as patients integrate speed, rhythm, and cognitive distractions, allowing their brains to process visual information more efficiently. By this stage, patients can shift their energy toward interpreting what they see rather than focusing on how to see it correctly.
