Accommodation Issues After a Concussion: Why Focusing Your Eyes Feels So Hard

Accommodation Issues After a Concussion: Why Focusing Your Eyes Feels So Hard

At our Kansas City clinic, Dr. Lance Stevenson, DC frequently evaluates patients with post-concussion eye strain, blurred vision, and fatigue, many of whom are struggling with this exact issue.

What Is Accommodation?

Accommodation is your eye’s ability to change focus from far to near — and back again. This is controlled by the ciliary muscles in your eyes, which adjust the shape of the lens so you can maintain a clear image whether you’re:

• Reading a book

• Looking at your phone

• Driving and checking mirrors

• Switching between your screen and paperwork

• Taking notes while watching a lecture

After a concussion, this ability can be disrupted — especially if there's damage to visual processing areas of the brain or cranial nerves involved in eye movement.

Signs and Symptoms of Accommodation Dysfunction After Concussion

Patients from Overland Park, Lee’s Summit, Shawnee, and Liberty often report:

• Blurred vision when reading or using a screen

• Difficulty shifting focus between near and far objects

• Eye strain or tired eyes after short visual tasks

• Headaches that start behind the eyes

• Slow reading speed

• Intermittent clarity — objects go in and out of focus

• Feeling like your glasses “aren’t working” anymore

• Fatigue after just 5–10 minutes of screen time or reading

If you’ve said “my vision feels off, but my eye doctor says everything looks fine,” accommodation dysfunction may be the reason.

Why Does This Happen After a Concussion?

Accommodation relies on more than just the eyes — it also depends on smooth coordination between:

• The cranial nerves controlling eye muscles

• The visual cortex in your brain

• The autonomic nervous system, which controls pupil and lens function

• Eye teaming and focusing systems (binocular vision)

A concussion — even a mild one — can disrupt these systems and cause your focusing muscles to become delayed, fatigued, or uncoordinated.

How We Diagnose Accommodation Issues in Kansas City

At our personal injury clinic, Dr. Lance Stevenson, DC includes accommodation testing as part of every post-concussion exam. This includes:

• Near point of accommodation: How close you can bring an object before it goes blurry

• Accommodation facility: How quickly you can shift between near and far

• Binocular and oculomotor coordination: Whether your eyes are working as a team

These tests often reveal problems missed in routine eye exams or emergency room evaluations.

Treatment Options for Accommodation Dysfunction

The good news: accommodation issues are highly treatable, especially when caught early.

We build customized rehabilitation plans that may include:

✅ Accommodation rock exercises – Practicing near-far focus shifts with targets or lenses
✅ Lens flipper therapy – Using alternating lenses to improve flexibility of focus
✅ Convergence and oculomotor training – Supporting the overall visual system
✅ Screen modifications – Blue light filters, text size changes, visual breaks
✅ Collaborative care – In severe cases, we may refer to a Kansas City neuro-optometrist for prism lenses or vision therapy

We also coordinate accommodation therapy with vestibular and cervical spine rehab, since visual symptoms often overlap with dizziness, balance issues, and neck dysfunction.

You Don’t Have to Live With Fuzzy Vision After a Concussion

Accommodation problems can make simple tasks like reading, driving, or using a screen feel overwhelming. But with the right care, your brain and eyes can relearn how to work together again.

At our Kansas City clinic, Dr. Lance Stevenson, DC helps patients from Parkville, Independence, Blue Springs, and across the metro area recover fully — not just from the concussion itself, but from the visual and neurological issues it causes.
