Concussion and Vision: Why Your Child's Headaches Are Not Going Away

A concussion can affect much more than your child’s head.

After a concussion, many children complain of headaches, dizziness, light sensitivity, blurry vision, trouble reading, difficulty focusing, or feeling tired after schoolwork. Some children recover quickly. Others seem fine at first, but continue to struggle when they return to reading, screens, homework, sports, or a full school day.

This can be confusing for parents.

You may think:

“The scan was normal.”

“The pediatrician said to rest.”

“The headache should be better by now.”

“Why is school still so hard?”

One reason is that concussion can affect how the eyes and brain work together.

Vision is not always the only reason headaches continue after a concussion, but it is a piece that should be checked when symptoms are triggered by reading, screens, light, movement, or schoolwork.

Why Concussion Can Affect Vision

Your eyes do not work alone. They are controlled by the brain.

After a concussion, the systems that help the eyes focus, move, track, and work together can be affected. Your child may still be able to see 20/20 on an eye chart, but reading, copying, screens, and busy environments may feel much harder than before.

This is why a child can look “fine” but still not feel fine.

A regular eye chart only tells us part of the story. It does not always show how well the eyes are focusing up close, moving across a page, or teaming together during sustained schoolwork.

Common Vision Symptoms After Concussion

Vision symptoms after concussion may include:

• Headaches with reading or homework
• Blurry vision
• Double vision
• Light sensitivity
• Eye strain
• Eye pain
• Trouble focusing up close
• Trouble shifting focus from near to far
• Losing place while reading
• Words moving or swimming on the page
• Dizziness in busy visual environments
• Nausea with screens or movement
• Trouble copying from the board
• Needing frequent breaks
• Feeling tired after short periods of schoolwork

Some children can explain these symptoms clearly.

Others cannot.

A younger child may simply say, “My head hurts,” “I am tired,” “I cannot do this,” or “I do not want to read.”

Why Headaches May Continue After the Injury

Headaches after concussion can come from many causes.

They may be related to the brain injury itself, neck strain, sleep changes, stress, vestibular issues, light sensitivity, migraine patterns, medication use, or other medical concerns.

Vision can also contribute.

If the eyes are working too hard to focus, team, or track, your child may develop headaches during reading, screens, homework, or school.

This often shows up as a pattern.

• The headache may be worse after school.
• It may come on during homework.
• It may happen after screen use.
• It may improve with rest.
• It may be connected to bright lights, busy stores, scrolling, reading, or copying from the board.

That pattern is important. It helps the doctor understand whether the visual system may be part of the problem.

When Headache Symptoms Need Urgent Medical Care

Some symptoms after a head injury should not wait for an eye exam.

Seek urgent medical care right away if your child has:

• A headache that gets worse and does not go away
• Repeated vomiting or nausea
• Seizure or convulsions
• Slurred speech
• One pupil larger than the other
• Weakness, numbness, or poor coordination
• Extreme drowsiness or difficulty waking
• Confusion that is getting worse
• Unusual behavior that concerns you
• Loss of consciousness
• Neck pain with concerning symptoms
• Symptoms that rapidly worsen

An eye exam is not a replacement for emergency care or medical concussion management.

If your child has danger signs, they need medical attention first.

Why School Feels Harder After a Concussion

Many children can rest at home and feel better, then struggle when they return to school.

That does not mean they are making it up.

School is visually demanding.

A typical school day requires your child to:

• Read small print
• Look from the board to the desk
• Use a Chromebook or tablet
• Track across lines of text
• Copy notes
• Move through bright hallways
• Process busy classrooms
• Shift attention between near and far
• Complete homework after a full day of visual effort

After a concussion, these tasks can be overwhelming.

A child may be able to do one worksheet, but not a full school day. They may be able to read for 5 minutes, but not 30. They may tolerate a quiet room, but not bright lights, movement, noise, and screens.

This is why return-to-school should be gradual for some children.

Reading Symptoms Parents Often Notice

Reading is one of the most common areas where concussion-related vision issues show up.

Parents may notice:

• Reading is slower than before
• The child loses place
• The child skips words or lines
• The child rereads the same sentence
• The child cannot remember what they read
• The child gets a headache after a few minutes
• The child closes one eye
• The child avoids homework
• The child needs someone to read directions out loud
• The child becomes emotional during schoolwork

This does not always mean the child has a reading disorder.

Sometimes the child’s eyes and brain are struggling to keep the print clear, single, and stable long enough to read comfortably.

Screen Symptoms After Concussion

Screens can be especially hard after a concussion.

Your child may complain that screens make their head hurt, make them dizzy, blur their vision, or make them feel sick.

This can happen for several reasons. Screens require sustained focus up close. They often involve scrolling, contrast, glare, brightness, and rapid visual movement. Children also tend to blink less when using screens, which can add dryness and irritation.

If your child is recovering from a concussion, screen use may need to be adjusted temporarily.

Helpful changes may include:

• Shorter screen sessions
• Frequent breaks
• Reduced brightness
• Larger text
• Printed materials when possible
• Audio support when appropriate
• Reduced scrolling
• Avoiding screens close to bedtime
• Using school accommodations during recovery

These changes do not replace care. They simply reduce visual load while your child is healing.

Light Sensitivity After Concussion

Light sensitivity is common after concussion.

Your child may be bothered by sunlight, fluorescent lights, bright classrooms, screens, white paper, or glare.

Some children want to wear sunglasses indoors. That may feel better in the moment, but it is important to talk with your child’s doctor before relying on indoor sunglasses all day. In some cases, too much avoidance of normal light can make light sensitivity harder to improve.

The right plan depends on the child.

Sometimes tinted lenses, environmental changes, breaks, or gradual re-exposure may be discussed. Sometimes the child needs medical concussion care, vestibular therapy, vision evaluation, or a combination of supports.

Eye Teaming Problems After Concussion

After a concussion, some children have trouble getting the two eyes to work together comfortably.

One common issue is convergence insufficiency. This means the eyes have trouble turning inward and staying together for near work like reading or screens.

Symptoms may include:

• Headaches with reading
• Eye strain
• Double vision
• Blurry vision
• Words moving on the page
• Trouble concentrating
• Losing place
• Avoiding near work

A child with convergence insufficiency may still see 20/20.

That is why parents may feel confused when they are told the child’s eyesight is normal, but the child still cannot tolerate reading.

Seeing clearly and using the eyes comfortably are not the same thing.

Eye Focusing Problems After Concussion

The eyes also need to focus clearly up close and then relax to see far away.

After a concussion, some children have trouble focusing.

They may say:

“The words get blurry.”

“It takes a second to focus.”

“The board is blurry after I look down.”

“My eyes feel tired.”

“I cannot switch from my paper to the board.”

Focusing problems can cause headaches, eye strain, blurry vision, and trouble with schoolwork.

This is especially frustrating for children because symptoms may come and go. They may see clearly for a short time, then blur after effort.

Eye Tracking Problems After Concussion

Reading requires the eyes to move accurately across words and lines.

After a concussion, some children have trouble with eye movements. They may lose place, skip lines, reread, or feel overwhelmed by paragraphs.

This can make reading feel slow and exhausting.

It can also affect sports, copying, driving for older teens, and moving through busy environments.

If your child says the words move, the page feels busy, or they cannot keep their place, tracking and eye movement should be checked.

Why a Regular Eye Chart May Not Explain the Symptoms

Many children with concussion-related vision symptoms can still read the eye chart.

That can be frustrating for families.

The child is saying they cannot read comfortably, but the chart says they can see.

Both can be true.

An eye chart checks clarity at a specific distance under a short testing condition. It does not always show what happens after 10 minutes of reading, screen use, or shifting focus all day in school.

A more complete exam looks at how the visual system functions, not just whether the letters are clear for a few seconds.

What Should Parents Track at Home?

Before the eye exam, write down the symptom pattern.

Helpful details include:

• Date of the concussion
• How the injury happened
• Whether there was loss of consciousness
• Current symptoms
• What triggers headaches
• Whether symptoms happen with reading
• Whether screens make symptoms worse
• Whether bright light bothers your child
• Whether your child has dizziness or nausea
• How long your child can read before symptoms start
• Whether symptoms are improving, worsening, or staying the same
• What accommodations are currently being used at school
• Whether your child had vision problems before the concussion

This helps the doctor see the full picture.

It also helps separate general recovery symptoms from symptoms that may be more visually triggered.

What Happens During an Eye Exam After Concussion?

An eye exam after concussion may include:

• Visual acuity
• Glasses prescription
• Eye health
• Pupil responses
• Eye alignment
• Eye teaming
• Convergence testing
• Eye focusing
• Eye movement
• Depth perception
• Light sensitivity discussion
• Symptom review
• School and screen tolerance discussion

The goal is to understand whether the eyes are contributing to your child’s headaches, reading fatigue, blur, double vision, dizziness, or screen intolerance. (Here is what to expect at a comprehensive pediatric eye exam.)

If the exam shows a vision problem, the doctor can explain the next step.

If the exam is normal, that is also useful. It helps you and your child’s medical team look more closely at other causes.

Does My Child Need Glasses After a Concussion?

Maybe, but not always.

Some children need a new glasses prescription after a concussion because their visual demands have changed or an old prescription is no longer comfortable.

Some may benefit from a temporary lens support for near work.

Some may need treatment for eye teaming or focusing.

Some may not need glasses at all.

The right plan depends on the findings.

It is important not to assume that all concussion vision symptoms are fixed with glasses. It is also important not to assume glasses cannot help. The exam helps sort that out.

When Vision Therapy May Be Considered

Some children have persistent eye teaming, focusing, or tracking problems after concussion.

If those problems are affecting reading, schoolwork, headaches, or screen tolerance, vision therapy may be discussed.

Vision therapy is not a treatment for the brain injury itself. It is used when specific visual skills need rehabilitation, such as eye teaming, focusing, or eye movement control.

Not every child with a concussion needs vision therapy.

Some children recover with time, medical management, school accommodations, and gradual return to activity.

Others need more targeted help.

The decision should be based on testing, symptoms, and how the child is functioning.

What School Accommodations May Help During Recovery?

Some children need temporary school support after concussion.

Depending on the child’s symptoms, accommodations may include:

• Shortened reading assignments
• Printed notes
• Reduced screen time
• Audiobooks or text-to-speech
• Breaks during near work
• Larger print
• Reduced copying from the board
• Extra time for assignments
• Sunglasses or hat use when appropriate
• Dimmed screen brightness
• Rest breaks in a quiet area
• Gradual return to full workload

Accommodations should be based on the child’s symptoms and recovery plan.

The goal is not to avoid school forever. The goal is to let the brain and visual system recover while the child continues learning as safely and comfortably as possible.

What If Your Child Had Vision Problems Before the Concussion?

This matters.

Some children already had focusing, eye teaming, tracking, or prescription issues before the injury. A concussion can make those problems worse or make the child less able to compensate.

Parents may say:

“My child always struggled a little with reading, but now it is much worse.”

“She had headaches before, but now they are constant.”

“He used to manage homework, but now he cannot get through it.”

This history is important. It helps the doctor understand whether the concussion created a new vision problem, worsened an existing one, or reduced the child’s ability to compensate.

When Should You Schedule an Eye Exam?

Schedule an eye exam after concussion if your child has:

• Headaches with reading
• Blurry vision
• Double vision
• Light sensitivity
• Eye strain
• Dizziness with visual tasks
• Trouble focusing
• Trouble with screens
• Trouble copying from the board
• Losing place while reading
• Words moving on the page
• Symptoms that return when schoolwork increases
• Symptoms that are not improving as expected
• A history of eye teaming, focusing, or reading-related vision concerns

You should also follow the care plan from your child’s pediatrician, neurologist, sports medicine doctor, or concussion specialist.

Eye care is one part of concussion recovery, not the whole plan.

Concussion Vision Care at Pediatric & Family Vision

At Pediatric & Family Vision, we evaluate children and teens who continue to have headaches, blurry vision, double vision, light sensitivity, reading fatigue, or screen intolerance after concussion.

We look at more than whether your child can read the eye chart. We check eye health, prescription, focusing, eye teaming, tracking, and how the visual system is functioning during near work.

If your child needs glasses, we will explain why. If your child needs accommodations, we can help document visual concerns that may be affecting schoolwork. If more detailed developmental or binocular vision testing is needed, we will guide you through that next step.

Concussion recovery can be frustrating for families because the child may look fine on the outside but still struggle with school, screens, reading, and headaches.

If your child’s headaches are not going away, and they are worse with reading, screens, light, or schoolwork, their eyes may need a closer look.
