Concussion Vision Therapy
Understanding Vision Problems After a Concussion
Your brain controls nearly every aspect of your vision, including eye movements, focus, and how you process what you see. When a concussion occurs, it can damage the pathways that coordinate these functions. This disruption often affects multiple areas of the visual system at once.
The injury may impact regions responsible for eye teaming, depth perception, and visual attention. Even a mild concussion can create problems with how your eyes track moving objects or shift focus between near and far distances.
Many people notice vision changes within hours or days of their concussion. These symptoms can range from mildly annoying to severely disabling. We often hear patients describe their world as visually overwhelming or exhausting.
- Blurred or double vision that comes and goes
- Difficulty reading or losing your place on the page
- Headaches that worsen with visual tasks
- Sensitivity to bright lights or glare
- Trouble judging distances or feeling unsteady
Certain factors make some individuals more likely to experience lasting vision difficulties after a concussion. Athletes who play contact sports face repeated head trauma, which compounds the risk. Previous concussions, even from years ago, can make your visual system more vulnerable to new injuries.
Older adults and those with pre-existing vision conditions may also experience longer recovery times. Children and teenagers sometimes struggle more because their visual systems are still developing.
Not all concussion symptoms show up immediately after the injury occurs. Your brain may compensate for damaged pathways at first, masking vision problems until you return to normal activities. When you start reading, using screens, or going back to work or school, the visual demands reveal underlying dysfunction.
Inflammation and metabolic changes in the brain evolve over time, which can trigger delayed symptoms. Delayed onset is common after concussion. If symptoms are new, worsening, or concerning, seek medical care right away.
Get an initial medical evaluation to confirm the concussion diagnosis and to screen for serious brain or eye injuries. This may include a neurologic exam and, when indicated, imaging.
Rest for 24 to 48 hours, then return to light activity as tolerated. Avoid alcohol and high-risk activities. People on blood thinners or with bleeding risk need prompt medical review.
Most post-concussion vision problems improve with proper treatment and rest. However, certain red flags require immediate medical attention. We recommend seeking emergency care if you experience sudden vision loss, severe eye pain, or pupils of unequal size.
- Sudden blindness or vision loss in one or both eyes
- A curtain or shadow blocking part of your visual field
- Severe headache with vomiting and vision changes
- Increasing confusion or difficulty staying awake
- New weakness, numbness, slurred speech, or facial droop
- Repeated vomiting or a seizure
- Severe neck pain or stiff neck after the injury
- Fluid or blood draining from the nose or ear
- New flashes and floaters or many new floaters after trauma
- New droopy eyelid with double vision
Call 911 or go to the emergency department if any of these occur.
What a Neuro-Optometrist Does for Concussion Recovery
Neuro-optometrists complete advanced training beyond standard optometry school to understand how brain injuries affect vision. We study the complex relationship between neurological function and visual performance. This expertise allows us to identify subtle problems that might be missed during a routine eye exam.
Our training includes learning specific rehabilitation techniques designed to retrain the visual system after neurological injury. We stay current with research on concussion and vision to offer evidence-based treatments.
When you visit our office for a post-concussion evaluation, we perform a much more detailed exam than a standard vision check. We assess not only your ability to see clearly but also how well your eyes move, team together, and process visual information. The evaluation typically takes longer than a regular eye exam.
We measure your eye alignment, focusing ability, and tracking skills under various conditions. This comprehensive approach helps us understand exactly which parts of your visual system need rehabilitation. We also examine ocular health, including a slit-lamp exam, intraocular pressure, and a dilated retinal and optic nerve evaluation to rule out traumatic eye disease.
A traditional eye exam primarily checks whether you need glasses and screens for eye diseases. While important, this approach does not evaluate the functional skills your visual system needs for daily activities. Neuro-optometric exams focus on how your eyes work together and communicate with your brain.
- Testing eye movements in multiple directions and speeds
- Measuring how your eyes converge on near objects
- Evaluating your ability to shift focus quickly
- Assessing visual processing speed and accuracy
- Checking for visual field defects or blind spots
Concussion recovery often requires coordination among several healthcare providers. We communicate with your primary care doctor, neurologist, or sports medicine physician to ensure everyone understands your visual challenges. This team approach creates a complete treatment plan that addresses all aspects of your recovery.
We may also collaborate with physical therapists, occupational therapists, or vestibular specialists when your symptoms involve balance or dizziness. Sharing information helps us determine which therapies will benefit you most.
Certain findings require referral to a neuro-ophthalmologist or additional testing to rule out serious complications. We coordinate this care promptly when indicated.
- Afferent pupillary defect, optic disc swelling, or unexplained reduced color vision
- Homonymous visual field loss or persistent field defects
- New cranial nerve palsy causing diplopia or ptosis
- Persistent, unexplained vision loss or severe photophobia not improving
- Signs of ocular trauma or suspected optic nerve injury
- Progressive neurologic symptoms or headache not responsive to care
Diagnostic Tests for Post-Concussion Vision Problems
We assess how smoothly and accurately your eyes follow moving targets and jump between stationary objects. These skills are essential for reading, driving, and sports. After a concussion, many people develop jerky or inaccurate eye movements that strain the visual system.
During testing, we may ask you to track a moving object with your eyes while keeping your head still. We observe whether your eyes move together, overshoot targets, or require multiple attempts to find the right position. We may use standardized tools such as VOMS, NSUCO, DEM, King-Devick, or instrumented eye-tracking when available. We document baseline findings and track change over time to guide treatment.
Your eyes must turn inward and adjust their focus when you look at something close, like a phone or book. This process, called convergence and accommodation, often breaks down after head trauma. We measure how close an object can come to your nose before you see double or experience discomfort.
- Near point of convergence testing to check eye teaming
- Accommodative amplitude to measure focusing range
- Facility testing to evaluate how quickly you shift focus
- Stamina assessments for sustained near work
- Positive and negative fusional vergence ranges at distance and near
- Maddox rod and von Graefe phoria measurements
- Accommodative facility with flipper lenses
We document baseline findings and track change over time to guide treatment.
Concussions can create blind spots or reduce your awareness of objects in your peripheral vision. We map your entire visual field to identify any areas where you cannot detect light or movement. This testing is especially important if you plan to return to driving or activities that require good side vision.
Some tests use computerized equipment that presents lights at various locations while you focus on a central target. Other methods involve moving objects from outside your field of view toward the center. Automated static perimetry helps quantify any field loss and is often needed for driving clearance.
When your eyes do not align properly, your brain receives two different images instead of one clear picture. Manifest misalignment is called strabismus and latent misalignment is called phoria. This forces your brain to work harder and can cause double vision, eyestrain, and headaches. We use specialized lenses and prisms to measure even tiny alignment problems.
Cover tests reveal whether one eye drifts when the other is covered, while prism measurements determine the degree of misalignment. These findings guide our treatment recommendations, including whether you might benefit from prism lenses.
Many concussion patients become extremely sensitive to bright lights, glare, or certain colors. We evaluate your light sensitivity and may test how quickly and accurately you process visual information. These assessments help us understand whether you need tinted lenses or other modifications to reduce symptoms.
- Photophobia screening with different light intensities
- Contrast sensitivity testing for low-light vision
- Visual processing speed evaluations
- Pattern recognition and visual memory tasks
We also use standardized symptom scales, such as the Convergence Insufficiency Symptom Survey and Post-Concussion Symptom Scale, to track change over time.
Vision Therapy Treatment Approaches
Vision therapy involves structured activities designed to improve specific visual functions damaged by your concussion. We create a personalized program targeting your unique combination of deficits. These exercises retrain your brain and eyes to work together more efficiently.
You will perform some exercises in our office under supervision and practice others at home. The program typically progresses from simple tasks to more complex activities as your skills improve. Consistency and regular practice are essential for achieving the best results.
Prism lenses bend light before it enters your eyes, helping to realign images and reduce double vision or eyestrain. We may prescribe prisms either as a temporary aid during recovery or as a long-term solution if your alignment does not fully normalize. Some patients notice relief with properly prescribed prism glasses, while others require adjustment time.
Prisms can cause motion distortion or imbalance for some people and may require adaptation. Use caution with new prisms during driving and complex mobility, and report any worsening diplopia or imbalance.
We might also recommend tinted lenses to reduce light sensitivity or specialized filters to improve visual comfort. These optical interventions often work best when combined with active vision therapy exercises. Tints should be individualized and re-evaluated regularly to avoid over-darkening.
Several clinically used programs with emerging evidence target specific visual skills affected by concussion. These interactive activities allow precise control over difficulty level and provide immediate feedback on your performance. We may incorporate computer training as one component of your broader rehabilitation plan.
- Eye movement exercises with adjustable speed and complexity
- Visual attention and processing tasks
- Reaction time and hand-eye coordination activities
- Tracking and focusing challenges with performance metrics
Unsupervised brain-training apps are not a substitute for a clinician-guided rehabilitation plan.
Your visual system works closely with your inner ear and balance mechanisms to keep you stable and oriented. Concussions often disrupt this integration, causing dizziness, unsteadiness, or motion sensitivity. We use exercises that combine eye movements with head movements and balance challenges to restore normal function.
These activities might include tracking objects while walking, maintaining balance while shifting your gaze, or coordinating head and eye movements. The goal is to reduce your symptoms during movement and improve your overall stability.
Specific exercises target your ability to focus at different distances and turn your eyes inward for close work. These activities build stamina and flexibility in the muscles that control focusing and eye teaming. We gradually increase the difficulty and duration to strengthen these critical skills.
Common techniques include near-far focusing drills, convergence push-ups, and activities using specialized equipment like Brock strings or vectograms. Most patients notice reading and screen work become easier as these functions improve.
Vision therapy works best when integrated with other forms of concussion rehabilitation. If you continue to experience headaches, neck pain, or cognitive difficulties, we may recommend adding physical therapy, cognitive therapy, or counseling to your treatment plan. Some symptoms require a multidisciplinary approach for complete resolution.
We monitor your progress closely and communicate with other providers to adjust your care as needed. The decision to add services depends on your specific symptoms, functional goals, and response to initial treatments.
Safety, Risks, and Limitations
Vision therapy and prism lenses are generally well tolerated, but some patients experience temporary side effects as their visual system adapts. Be aware of these common reactions and report any concerns to our office.
- Temporary headaches, eye strain, or nausea during or after exercises
- Dizziness or motion sensitivity with vestibular-ocular work
- Visual discomfort when starting prisms or tints
- Fatigue or brain fog after sessions
- Increased symptoms if exercises progress too fast
Most mild discomfort during vision therapy resolves on its own as you adapt. However, certain symptoms require stopping therapy and getting medical attention right away.
- New or rapidly worsening double vision, severe headache, or neurologic changes
- Falls or near falls after new lens or prism changes
- Vomiting, syncope, or prolonged recovery after home exercises
Vision therapy is one component of a comprehensive concussion recovery plan. Depending on your symptoms and goals, we may recommend other strategies or refer you for additional services.
- Short-term occlusion (patch or Bangerter foil) to manage disabling diplopia
- Migraine management and sleep optimization
- Vestibular and cervical spine rehabilitation
- Graded exposure to visual motion environments and optokinetic therapy when indicated
Home-Based Care and Activity Modifications
Digital devices place heavy demands on your visual system, often triggering or worsening concussion symptoms. We recommend limiting screen use during the early stages of recovery and gradually increasing exposure as tolerated. Taking frequent breaks helps prevent symptom flare-ups.
- Follow the 20-20-20 rule: every 20 minutes, look 20 feet away for 20 seconds
- Reduce screen brightness and increase text size
- Position screens at arm's length and slightly below eye level
- Use artificial tears if your eyes feel dry during screen work
- Stop immediately if symptoms worsen and rest before resuming
Harsh overhead lights and bright sunlight commonly trigger headaches and discomfort in people recovering from concussions. We suggest using softer, indirect lighting whenever possible and wearing sunglasses outdoors. Creating a visually comfortable environment supports healing and allows you to function better.
Avoid fluorescent lights if they bother you, and consider using lamps with adjustable brightness. Natural light is often easier to tolerate than artificial sources, but you may need to filter it with curtains or blinds during peak brightness hours. Avoid wearing dark sunglasses indoors for long periods, because this can worsen light sensitivity over time.
Pushing through visual activities when symptoms appear can slow your recovery and increase frustration. We encourage you to listen to your body and take breaks before you reach your limit. Gradually building your tolerance works better than forcing yourself to power through discomfort.
Keep a symptom diary to identify which activities trigger problems and how long you can perform them comfortably. This information helps us adjust your therapy program and gives you concrete goals for increasing your activity tolerance.
Specific tint colors can reduce light sensitivity and improve visual comfort for some concussion patients. We may recommend trying tinted glasses in colors like rose, amber, or gray to see if they help your symptoms. Some people benefit from specialized filters that block certain wavelengths of light.
- FL-41 tints for light sensitivity and migraine-related symptoms
- Polarized lenses to reduce glare from reflective surfaces
- Blue light filters for computer and device use
- Photochromic lenses that darken outdoors automatically
Plan to use the lightest effective tint indoors and wean as symptoms improve, since darker tints can reduce contrast and may affect color-dependent tasks and driving.
Returning to normal activities should happen gradually based on your symptom levels, not a fixed timeline. Start with short periods of reading or work tasks and slowly increase duration as tolerated. We help you create a realistic plan for resuming school, work, or hobbies without causing setbacks.
Most people benefit from a phased return that includes accommodations like extra breaks, reduced hours, or modified duties. Communicate openly with your employer or school about your needs during recovery so they can provide appropriate support.
Resume physical activity in stages. Begin with light aerobic activity and progress gradually as long as symptoms do not worsen.
Avoid contact or high-risk sports until medically cleared by your healthcare team.
