Understanding Post-Concussion Vision Testing: Why 20/20 Isn’t the Whole Story

After a concussion, it’s not uncommon for patients to feel frustrated. Their regular eye exam may say everything looks normal—yet they still struggle with reading, working on screens, or focusing throughout the day. If this sounds familiar, you're not alone.

At A B See Optometry and Vision Therapy, we specialize in uncovering the root causes of post-concussion vision problems. A standard eye exam may test how clearly you can see, but it often misses critical aspects of how your visual system functions. That’s why a specialized concussion vision assessment is so important.

Why Is a Concussion Vision Exam Necessary?

While a general eye exam checks for overall eye health and vision clarity, it doesn’t evaluate how well your eyes work together—and that’s where many post-concussion issues begin.

Concussions can affect parts of the brain responsible for visual coordination, focus, and stamina. These subtle disruptions often go undetected in a routine exam, but they can significantly impact your daily life.

What Makes a Concussion Vision Assessment Different?

At A B See Optometry and Vision Therapy, our concussion vision assessments dive deeper into the mechanics of your visual system. We look beyond “20/20” vision and focus on how your eyes function as a team.

Here’s what sets our testing apart:

1. Eye Coordination Testing

This evaluates whether your eyes are working together effectively. Many concussion patients experience binocular vision issues, which can lead to double vision, eye strain, or difficulty reading. We measure how well your eyes align and converge—especially when focusing on close-up tasks.

2. Visual Stamina Testing

Even if your eyes work well initially, can they maintain performance over time? Stamina testing reveals how long your visual system can sustain effort before symptoms like headaches or blurry vision set in. This is especially critical for patients who spend hours reading, studying, or working on screens.

3. Focusing Ability Evaluation

Your eyes’ ability to quickly and accurately focus at different distances can be disrupted after a concussion. We test for accommodative issues—like intermittent blurriness or visual fatigue—often linked to post-injury symptoms.

Why Do I Still Struggle Even If I Have 20/20 Vision?

Many patients are surprised to learn that clear vision doesn't guarantee a healthy visual system. You may see clearly on a basic eye chart, but still experience:

Blurry or fluctuating vision
Trouble concentrating on reading or digital devices
Headaches or dizziness after visual tasks
Eye strain or fatigue

These symptoms often stem from functional vision problems that require a more detailed evaluation—something a concussion vision assessment is designed to address.

How Vision Therapy Supports Concussion Recovery

If your assessment uncovers visual dysfunction, vision therapy may be recommended. Vision therapy is a personalized, non-invasive program that retrains your brain and eyes to work together more efficiently.

At A B See Optometry and Vision Therapy, we create customized neuro-optometric rehabilitation plans to help concussion patients:

Restore eye coordination and control
Improve focusing and visual endurance
Reduce symptoms like headaches, double vision, and reading fatigue

With guided therapy, many patients experience lasting relief and a noticeable improvement in their ability to work, learn, and enjoy daily life again.

Take the Next Step Toward Recovery

If you’ve had a concussion and still struggle with reading, screen time, or visual fatigue—even if your last eye exam looked normal—it may be time to dig deeper.
