Vision and ADHD in kids: What parents should know
Some vision problems can share signs and symptoms with ADHD in children. Understanding the differences can help families get the right care and support.
Some children may need extra support staying focused in the classroom, following directions or completing schoolwork. Or they may have trouble sitting still, raising their hands before answering or working with their classmates.1
When kids show these types of behavior, many teachers and parents assume they may have attention-deficit/hyperactivity disorder, or ADHD. ADHD is a mental health condition. It’s most often diagnosed in children, but adults can have it too.2
ADHD affects how children focus, stay organized and control impulses. But not all attention problems are caused by ADHD. Some kids may actually be having issues with vision.
How vision problems can affect learning and behavior
Seeing clearly is only one part of vision. The brain and eyes also work together to track objects, stay focused and process visual information. When these skills do not work well, children may have difficulty with school tasks.3
For example, a child who has trouble tracking words across a page may lose their place while reading. As a result, they may have trouble with comprehension.4 That can be frustrating. Or it may even cause a child to avoid reading or doing homework.5
Or if the eyes can’t focus right, kids may not be able to read for a long time. They may say their eyes are tired or they have headaches.4
Much of learning, especially in the elementary-school years, is visual. Kids need their eyes to read, write, work on computers and see the board. But as many as 1 in 4 school-aged children may have some type of vision problem.4

The link between ADHD and vision problems
Research shows that visual disorders are more common in children with ADHD. And when children have ADHD plus another learning disorder, eye conditions are even more common.6
These include issues with visual clarity — meaning children are more likely to: 6
- Have blurry vision
- Be nearsighted
- Have trouble seeing details clearly
- Need stronger prescriptions
Children diagnosed with ADHD may also be more likely to have a condition called convergence insufficiency. This affects how the eyes work together when looking at close objects.7
One theory for the link: The same factors that affect attention and learning may also affect how the brain handles visual information, even when eyesight is normal.6

Common signs to watch for
Vision-related problems don’t always show up as blurry vision. Instead, they may appear as behavior or learning challenges. Some common signs include:5
- Skipping words or losing place on a page
- Squinting or covering one eye
- Blinking or rubbing the eyes a lot
- Trouble remembering what they’ve read
- Complaints of eye strain during reading or screen time
- Frequent headaches, especially after close work
- Trouble getting and staying organized
UnitedHealthcare Vision offers a huge selection of eyeglasses that may be a good match for your child — and vision insurance can help pay for them.
How to get the right diagnosis for vision problems
Many schools offer basic vision screenings. These screenings usually check how well a child can see letters on a chart at a distance. While helpful, they don’t test all aspects of vision.
Some skills aren’t typically included in school screenings like:
- Eye tracking
- Focusing
- Eye Coordination
But they’re done during a full eye exam by an eye care provider.
During a comprehensive eye exam, the provider checks how well the eyes work together and how well they focus. These tests can help spot vision issues that may not be as obvious as nearsightedness.4
If the provider finds a problem, treatment may include glasses or vision therapy. Addressing these problems can make reading and schoolwork easier.
Good habits for kids’ eyesight
Simple changes can also help reduce eye strain and protect a child’s vision. These may include:8,9
- Taking regular breaks during homework or screen time
- Keeping screens 18 to 24 inches from the eyes
- Encouraging outdoor play and activities, which support eye health
Attention and behavior challenges can have many causes. A child’s eyesight is one piece of the puzzle that is sometimes overlooked. Start by making an appointment with an eye care provider who can help find the cause of vision-related problems.
