Concussions and Their Effect on Vision: Understanding Changes That Can Affect Daily Life

After a head injury, it can be frustrating to feel that your vision has changed while a quick check of eyesight seems normal. Personalised eye care allows time to listen carefully to the situations that trigger symptoms, rather than treating a vision concern as a simple question of whether letters on a chart look clear.

Key Takeaways

• A concussion can affect how the brain coordinates eye movements, focusing ability, balance, and visual attention.
• Symptoms may include blur, double vision, light sensitivity, difficulty reading, visual fatigue, or discomfort in busy environments.
• Clear distance vision does not always rule out a concussion-related visual concern.
• An in-clinic assessment can help identify whether further care or referral is appropriate through our Our Eyecare Services.

At The Focal Point Optometrist, we take time to understand how a head injury may be affecting your day-to-day visual comfort. We assess the eyes and visual system in context, including the tasks that now feel more difficult, such as reading, screen use, driving, walking through crowded spaces, or changing focus between distances.

We also recognise that symptoms can feel unsettling even when they are intermittent. Being properly seen and heard means having space to explain what has changed, receiving clear information about possible next steps, and knowing when an optometrist, General Practitioner (GP), ophthalmologist, or another health professional may need to be involved.

Why This Issue Should Not Be Ignored

A concussion is a type of mild traumatic brain injury that can temporarily affect the way the brain processes information. The eyes themselves may look healthy, yet a head injury can alter the communication between areas of the brain that help control eye movements, visual attention, focusing ability, and balance.

This does not mean every concussion will cause visual symptoms. Some people notice no change at all, while others experience symptoms immediately or only when they return to demanding tasks. Symptoms can also vary from day to day and may become more noticeable with fatigue, concentration, bright light, movement, or extended screen use.

Vision is an active process. The brain must combine information from both eyes, keep images stable while the head moves, shift attention between targets, and interpret what is happening in the surrounding environment. When head trauma disrupts some of this coordination, the result can be blur, discomfort, disorientation, or difficulty completing visual tasks that previously felt routine.

A thorough assessment matters because new visual symptoms after a head injury can have more than one cause. An optometrist can assess eye health and visual function, while urgent or complex signs may require timely referral to a GP, ophthalmologist, neurologist, or emergency service.

Common Symptoms or Challenges

Concussion-related visual symptoms can involve clarity, comfort, eye coordination, or the way visual information is processed. A person may describe print moving on a page, losing their place while reading, sore eyes after screen use, or difficulty holding a single clear image when looking at something close.

Blurred vision may occur when the eyes are working harder to keep images aligned or when focusing ability is less flexible after the injury. Double vision can occur if the eyes are not coordinating comfortably together. These symptoms may be occasional rather than constant, and they can appear during reading, computer work, driving, or rapid shifts of gaze.

Light sensitivity is another common concern. Bright sunlight, indoor lighting, screen glare, and high-contrast patterns can be uncomfortable and may contribute to headaches or visual fatigue. Some people also find scrolling, watching moving traffic, or walking through supermarkets more difficult because visual motion can feel overwhelming.

Balance and vision are closely connected. A head injury can disrupt the way the visual and balance systems work together, particularly when the head moves. This can contribute to dizziness, nausea, a feeling that the environment is moving, or difficulty feeling steady in visually busy spaces.

Reading can be especially demanding because it relies on accurate eye movements, stable attention, comfortable eye teaming, and flexible focusing ability. When one or more of these skills is affected, a person may skip lines, reread words, lose their place, or tire more quickly than usual.

What Personalised Eye Care Actually Looks Like

Personalised care begins with listening to the details that may not appear on a standard Eye Test. We may ask when the symptoms started, whether they happen at near or far distances, what activities bring them on, whether head movement makes them worse, and whether there are associated concerns such as headaches, dizziness, or difficulty concentrating.

Our optometrists can assess visual clarity, eye health, eye alignment, eye movements, focusing ability, and how comfortably the eyes work together. Depending on the history and symptoms, this may include looking at how the eyes follow a target, move between targets, maintain alignment at close distances, and respond as focus changes.

These assessments are performed in-clinic and are tailored to the individual. They are not designed to replace medical concussion care. Instead, they help clarify whether a visual factor may be contributing to ongoing symptoms and whether monitoring, practical visual support, or referral is appropriate.

In some cases, the assessment may indicate that the concern is outside the scope of routine optometric management. Sudden persistent double vision, loss of part of the visual field, unequal pupils, worsening severe headache, repeated vomiting, new flashes, or a sudden onset of spots in vision should be treated as urgent concerns. We can help direct patients to the appropriate level of care, but emergency symptoms require prompt medical attention.

The Value of Ongoing Care With a Consistent Optometrist

Symptoms after concussion can change as a person returns to work, study, driving, exercise, or everyday responsibilities. Ongoing care with a consistent optometrist can make it easier to compare symptoms over time and keep the assessment focused on the visual situations that matter most to you.

At our small, independent family optometry practice in Wembley, Western Australia, we value longer consultations and continuity of care. An initial consultation for ongoing post-concussion visual concerns is generally around one hour, allowing time to discuss your history, visual demands, and any relevant reports from other health professionals.

A consistent optometrist can also help coordinate care when several factors are involved. Concussion recovery may involve a GP, physiotherapist, neurologist, ophthalmologist, occupational therapist, or other health professional. Our role is to assess the visual component, monitor relevant findings, communicate where appropriate, and refer when specialist care is needed.

This approach avoids assuming that every symptom has one simple explanation. It also gives you an opportunity to raise changes that may feel minor but affect confidence, comfort, productivity, or safety in everyday life.

What to Expect at The Focal Point Optometrist

Your appointment begins with a conversation about the injury and the visual changes you have noticed. It can be helpful to mention whether symptoms occur while reading, on screens, in bright environments, while driving, during head movement, or in crowded places. Bringing any relevant medical information can help us understand the broader picture.

We then carry out an in-clinic Eye Test tailored to your symptoms. This may involve assessing the health of the eyes, visual clarity, eye movements, eye teaming, and focusing ability. The findings help us explain whether the visual system appears to be under added strain and whether another practitioner should be involved.

Please bring your Medicare card to your appointment. If the assessment identifies signs that need medical investigation or specialist management, we will explain why referral is recommended. For concerns requiring surgical or complex medical treatment, an ophthalmologist or GP is the appropriate provider.

You do not need to have every symptom perfectly described before attending. We encourage you to explain the situations that feel different since the head injury, even if the problem is intermittent. That information can be just as useful as a description of blur or double vision.

Practical Solutions and Reassurance

There is no single visual experience after concussion, and there is no assumption that every person will need the same support. The first step is understanding what is happening for you and identifying which visual demands are causing the greatest difficulty.

Depending on the assessment, your optometrist may discuss ways to reduce visual strain, monitor changes, or coordinate referral with your other health professionals. If ongoing eye movement, eye teaming, focusing ability, or visual processing concerns are identified, a tailored Vision Therapy Programmes assessment may be discussed where appropriate. Vision therapy is not presented as a quick fix, and suitability varies between individuals, but it can provide a structured avenue of support for selected visual skills.

The aim is to give you clear information and a realistic plan, not to make promises about recovery. We will explain what we can assess, what may need referral, and how we can continue to support your visual comfort and function as your needs change.

At The Focal Point Optometrist, we want people experiencing changes in vision after a concussion to feel listened to, respected, and supported. Our optometrists provide careful, individualised assessment and clear guidance about the most appropriate next step.

Frequently Asked Questions About Concussions and Vision

Can a concussion affect vision even if an Eye Test seems normal?

Yes. A standard Eye Test is important, but it may not capture every issue that occurs when the eyes need to move, coordinate, maintain focus, or process visual information during everyday activities. A concussion can affect these functions without causing an obvious change in basic distance clarity.

Can a head injury always cause visual symptoms?

No. A head injury can affect vision, but it does not always do so. Symptoms differ between individuals and can be influenced by the nature of the injury, recovery, visual demands, and other health factors. An assessment can help determine whether a visual concern may be contributing to your symptoms.

What should I bring to an appointment for post-concussion visual concerns?

Bring your Medicare card and any relevant information about the head injury, including reports or referral information if available. It is also useful to note the visual tasks that bring on symptoms, such as reading, using screens, driving, or being in bright or busy environments.

How long does an appointment take?

An initial consultation for ongoing visual concerns after a concussion is generally around one hour. This provides time to discuss your history, carry out appropriate in-clinic testing, and explain whether monitoring, further assessment, or referral is recommended.

Can vision therapy help after a concussion?

For some people, vision therapy may be considered after an optometrist has assessed specific concerns involving eye movements, eye teaming, focusing ability, or visual processing. It is not appropriate for every person, and outcomes vary. Your optometrist can explain whether a vision therapy assessment may be relevant to your individual findings.

When might referral be needed?

Referral may be needed when symptoms suggest a medical, neurological, or ophthalmic issue that requires further investigation. Our role is to assess the visual component, explain the findings clearly, and refer to a GP, ophthalmologist, neurologist, or emergency service when that is the most appropriate pathway.
