Yes — and this distinction is one of the most important concepts in concussion care. Standard eye exams measure acuity: how clearly you can see letters on a chart. What they do not measure is how the brain processes, coordinates, and interprets visual information. After a concussion, vision can appear normal on a standard exam while significant functional problems persist.

Visual processing issues after brain injury may include:

• Double or blurred vision that fluctuates throughout the day
• Difficulty tracking moving objects or reading across a line of text
• Balance problems triggered by visual input, such as crowded stores or scrolling screens
• Eye strain or headaches during tasks that require sustained visual focus
• Difficulty with depth perception or spatial orientation

These symptoms originate in the neural pathways that control eye movement and visual-vestibular coordination — not in the eyes themselves. Oculomotor and oculo-vestibular assessments evaluate how well the eyes and brain are communicating, identifying deficits that a standard optometry exam would never detect.
