Understanding headaches in children — and why a child who was told they see 20/20 can still get them after school, reading or screens.
Headaches after homework
If your child comes home from school with a headache, says their head hurts after homework or a tablet session, or squints and rubs their eyes through reading, it is worth asking a question most screenings never do: how hard are their eyes working to see?
Passing the eye chart means each eye can read small letters clearly at a distance. It says nothing about whether the two eyes aim together, hold focus up close, or move smoothly across a page — the skills a school day actually demands. When those skills are inefficient, the visual system compensates all day long, and that effort often shows up as a headache. This short explainer walks through why.
Four common reasons children get headaches — three of them visual, one of them not.
Excessive screen time can lead to digital eye strain, a common cause of headaches in children. Staring at a tablet, computer or phone for long stretches forces the eyes to focus intensely, often without enough breaks. That strain tires the eyes, causes discomfort and leads to headaches — especially after extended use. Regular screen breaks, proper lighting and sensible limits on screen time can reduce these headaches and improve your child’s comfort.
Uncorrected nearsightedness, farsightedness or astigmatism can lead to headaches in children. When the eyes struggle to focus clearly, the brain works overtime to compensate, causing strain and discomfort. That constant effort — especially during reading or screen time — can trigger headaches. Correcting the problem with glasses or other treatment can significantly reduce headaches and improve your child’s comfort and performance in everyday activities.
Binocular vision problems cause headaches because the two eyes struggle to work together and stay aligned. When the eyes aren’t aligned, the brain has to work harder to merge two images into one, leading to eye strain and fatigue. That extra effort, especially during reading and other close tasks, often ends in a headache.

Dehydration and lack of sleep are common causes of headaches in children, and they have nothing to do with the eyes. A dehydrated body lacks the fluids it needs to function properly, which can bring on a headache. Too little sleep keeps the brain and eyes from resting and recovering, causing tension and discomfort. Making sure your child stays hydrated and gets enough sleep helps prevent headaches and keeps them feeling their best.
Not every headache is a vision problem. If hydration and sleep are already solid and the headaches keep coming, that is when a closer look at vision makes sense.
Headaches that are tied to vision tend to travel with other signs. See how many of these sound familiar.
A comprehensive developmental and binocular vision evaluation goes well beyond the eye chart. For a child or adult with recurring headaches, Dr. Murray measures the visual skills that get taxed by reading, homework and screens — then explains the findings in plain language, with time for your questions.
Whether the two eyes aim at the same point and stay aligned at distance and near. Merging two misaligned images is a common source of strain.
How quickly and comfortably focus shifts and holds during near work like reading, homework and time on a tablet.
How smoothly and accurately the eyes move across a line of text or follow a moving target.
Whether nearsightedness, farsightedness or astigmatism is going uncorrected, plus overall ocular health.
How efficiently the brain interprets, remembers and acts on what the eyes take in during a school day.
You leave understanding the findings and the next steps — glasses, prism, vision therapy, or simply reassurance.
Families who came in for headaches, eye strain and reading fatigue — in their own words.
“Dr. Murray and her staff are wonderful! Getting an assessment and then Vision Therapy here has been super helpful for my daughter. She got headaches at school almost daily, and whenever she read she tired easily, lost where she was, and had a hard time staying focused on the text. All of this got much better with a few months of Vision Therapy. It was a commitment that was absolutely worth it!”
“My son was having troubles with reading and was getting headaches all the time. Dr. Murray and her staff helped us find what was going on. Through therapy we were able to ease his vision problems. My son went from struggling in school to being at the top of his class!”
“My son has been going here for about three months now. His handwriting has improved. He is more focused in school, and most importantly his headaches are gone. This program really seems to be working!”
“I was blown away by Dr. Murray's knowledge and communication about vision processing disorder, something we had never heard of at the time. She made my son very comfortable during the evaluation and spent a lot of time with us reviewing her findings and next steps. All of the staff is wonderful and knowledgeable. Highly recommend if you have any concern that your child may need this type of care.”
“The initial evaluation and consultation were so informative! It helped us answer so many of the question marks in my daughter's life. I have NEVER had a physician spend so much time and energy answering questions and getting me everything I needed to help my daughter be successful at school. I will say it isn't "cheap" but nothing good ever is. Worth every penny!”
“Already changed our son in just a few short weeks. As parents who were desperate for answers, we were relieved when Dr. Murray realized our 5-year-old simply needed visual processing therapy. We are already told from his kindergarten teacher that he is participating more and more, and the welcomed side effects of his therapy are increased self-confidence, self-calm, and true ability to learn quickly!”
“I wasn't sure about therapy at first but after a few sessions I noticed a huge difference in my daughter's academic performance. I highly recommend this place if you struggle with getting your eyes to work together and it impacts your school work or everyday life.”
“My daughter had surgery for her strabismus and it was recommended for her to go to a vision therapist to straighten her eyes. I truly believe it's been the best choice we could have made.”
