A concussion, a type of traumatic brain injury, can have a range of effects on the body, including vision. Understanding how long vision problems may persist after a concussion is crucial for those on the road to recovery. In this article, we’ll delve into the various aspects of post-concussion vision problems and what individuals can expect.

Can a concussion cause vision problems?

A concussion can indeed lead to a variety of vision problems. The impact on the brain can disrupt the normal functioning of the visual system, causing a range of symptoms that affect one’s ability to see clearly.

How does a concussion affect vision?

After a concussion, the brain’s processing of visual information may be impaired. This can result in a variety of vision-related issues, which can vary from person to person.

What are post-concussion vision problems?

Post-concussion vision problems refer to a range of visual disturbances that occur after sustaining a concussion or traumatic brain injury. These can include issues like blurry vision, double vision, difficulty focusing, post-concussion eye dilation, and more.

Kinds of Vision Symptoms That Can Occur After Concussion


After sustaining a concussion, individuals may experience a range of distressing vision-related symptoms that stem from the disruption of normal brain function.

These vision changes after concussion can manifest in various ways, including blurry vision, double vision, difficulty reading, eye strain or pain, and challenges in focusing on objects at close distances, all of which can significantly impact daily activities.

Blurry Vision

One of the most common vision issues is blurry vision after head injury or post-concussion. This can occur due to the disruption of the brain’s ability to process visual information accurately.

Double Vision

Concussions can lead to double vision (double vision concussion), a condition where a person sees two images of a single object. This occurs because the eyes may not be working together as they should.

Difficulty Reading

Some individuals may experience difficulty reading after a concussion. This can be due to challenges in focusing or tracking words on a page.

Eye Strain or Pain

Eye strain or pain may also be present, particularly during activities that require sustained visual concentration, such as reading or using a computer.

Difficulty Focusing at Near Distance

Concussions can affect the ability to focus on objects at close distances. This can be particularly troublesome for tasks that require detailed or intricate visual work.

What are the symptoms of post-concussion vision problems?

Apart from the specific vision-related symptoms or vision problems after concussion mentioned above, individuals may also experience these additional symptoms. These can compound the challenges individuals face in their daily activities, underscoring the importance of seeking timely medical attention and appropriate treatment for post-concussion vision problems.

How is post-concussion vision problems diagnosed?

A comprehensive evaluation by a healthcare professional, often including ophthalmologists and neurologists, is essential. Specialized tests may be conducted to assess visual acuity, eye movement, focusing abilities, and other aspects of visual function.


Here are the key steps typically taken in the diagnosis process:

  1. Medical History Review: Understanding the patient’s medical background, including any history of concussions or visual conditions, provides crucial context for the evaluation.
  2. Symptom Assessment: A detailed inquiry into specific visual symptoms, such as blurry vision, double vision, and difficulty focusing, helps pinpoint areas of concern.
  3. Visual Acuity Testing: This fundamental eye examination assesses the patient’s ability to see clearly at various distances, identifying any refractive errors or visual acuity deficits.
  4. Eye Movement Evaluation: Testing the coordination and smoothness of eye movements helps reveal any difficulties in tracking or following objects, which can be indicative of underlying issues.
  5. Pupil Examination and Light Sensitivity Assessment: Evaluating the pupils’ size, shape, and reactivity to light, along with assessing sensitivity to different light levels, provides valuable information about neurological and visual function.

Treatments That Improve Vision Following A Concussion

By combining these treatments, individuals can significantly improve their post-concussion vision problems, ultimately enhancing their overall quality of life and ability to engage in daily activities. It’s important to note that the specific treatment plan will be tailored to each individual’s unique needs and symptoms.

Vision Therapy

Concussion vision therapy is a specialized form of rehabilitation that involves a series of exercises and techniques designed to enhance visual skills and alleviate symptoms associated with post-concussion vision problems.

Optical Aids

These may include prescription glasses, prisms, or other specialized lenses that are prescribed to improve vision and provide more comfortable visual experiences.

Coordination Exercises

Specifically designed exercises that aim to improve the coordination between the eyes, allowing for better teaming and tracking of visual information.

Focusing Exercises

These exercises focus on training the eye muscles to adjust focus efficiently, helping individuals regain the ability to shift focus between near and far distances.

Visual Scanning and Tracking Activities

Activities that retrain the eyes to smoothly follow moving objects, which is crucial for tasks like reading and driving.

How long does it take for post-concussion vision problems to go away?

The duration of post-concussion vision problems can vary widely depending on the individual, the severity of the concussion, and the specific nature of the vision issues. Some may experience a resolution of symptoms within a few weeks, while others may require several months of therapy and recovery.

In most cases, with proper treatment and rehabilitation, post-concussion vision problems can be significantly improved, if not completely resolved. However, in rare cases, some individuals may experience long-term visual challenges.
