Eye tracking is a visual skill most people take for granted. It allows your eyes to smoothly follow moving objects, jump accurately from one point to another, and move across a line of text when reading. When eye tracking does not work well, it can cause problems with reading, learning, sports, and daily activities.
Eye tracking, also called visual tracking, describes a group of eye movement abilities. These include the ability to look at an object quickly and accurately, follow a moving object with your eyes, and shift focus from one point to another. These skills happen so naturally for most people that they do not think about them.
Good eye tracking is needed for many everyday tasks. Reading requires your eyes to move smoothly from word to word and line to line. Playing sports requires tracking a moving ball. Driving requires following other cars and road signs. When eye tracking does not work well, these tasks become much harder.
Eye tracking problems can affect people of all ages. Children are often affected the most because they are still learning to read and building the skills they need for school. However, adults can also have eye tracking issues, especially after a head injury or concussion.
Your eyes have a built-in lens that helps you see near and far objects clearly. When this focusing system does not work well, your vision may be blurry. Blurry vision makes it hard to keep your place on a page. You may lose track of which word or line you are reading.
Both eyes must work together to create a single, clear image. The muscles around your eyes and the nerve pathways between your eyes and brain must all function properly. When eye teaming is poor, you may see double or have blurry vision. Words on a page may seem to move or swim around.
Peripheral vision, or side vision, allows you to see both ends of a line at once. This helps guide your eye movements when reading. People with a narrower field of vision may only see a few words at a time. This makes it hard to track smoothly across a line of text.
Children and adults with eye tracking problems often struggle with reading. Common signs include skipping lines, losing their place frequently, and needing to use a finger or ruler to stay on the right line. They may also leave out words or swap words around when reading aloud.
Some people move their head excessively while reading instead of moving just their eyes. This is the body's way of compensating for poor eye tracking. You may also notice squinting, frequent blinking, or rubbing of the eyes during reading tasks.
People with eye tracking issues may complain that words seem to swim or float on the page. They may experience headaches or eye fatigue after reading. These symptoms often get worse as reading time increases.
Eye tracking problems can make it hard to catch, hit, or kick a ball. The eyes cannot follow the ball's movement accurately. As children get older, tracking issues may also affect their ability to drive safely.
The skills learned in a classroom at a young age build the foundation for future success. Eye tracking problems can make it hard to follow along in a textbook or copy notes from the board. This can cause a child to fall behind in their schoolwork.
It can be frustrating and discouraging to struggle with something that others seem to do easily. Children with undiagnosed eye tracking problems may think they are not smart or capable. This can hurt their self-confidence and their willingness to try new things.
Finding eye tracking problems early gives children the best chance to improve. Many parents and teachers assume a child who struggles with reading just needs more practice. A comprehensive vision evaluation can determine whether an eye tracking problem is the real cause.
Vision therapy is an effective treatment for eye tracking problems. It trains the eyes to move accurately and efficiently from target to target. The goal is to build the visual skills needed for reading, learning, and everyday activities.
Vision therapy involves weekly sessions with an optometrist and a trained vision therapist. Each session includes activities designed to strengthen specific visual skills. Home practice between sessions helps reinforce what is learned in the office.
With consistent therapy, many people see significant improvement in their eye tracking abilities. Reading becomes easier and less tiring. Sports performance may improve. Most importantly, the frustration of struggling with visual tasks often decreases.
At Insight Vision Center Optometry, Dr. Valerie Lam, OD, FAAO, FCOVD leads the vision therapy program, known as The Eye Gym. Dr. Lam is board certified in Vision Therapy and Pediatric Developmental Vision Care. Dr. Ariel Chen, OD also provides care for learning-related vision problems. The practice offers one-on-one therapist-guided sessions for children and adults.
Children can be tested for eye tracking problems as early as age five or six, when they begin learning to read. However, if a younger child shows signs of visual difficulty, an evaluation can be done earlier. Annual eye exams can help catch problems before they affect school performance.
Yes, adults can improve their eye tracking through vision therapy. While children often progress more quickly, adults with eye tracking problems from concussions, strokes, or lifelong issues can still see meaningful improvement with consistent treatment.
Treatment length varies depending on the severity of the problem and how consistently the patient practices. Many people notice improvement within a few months. A typical vision therapy program may last six months to a year for best results.
Glasses correct how light enters the eye but do not train the eye muscles or brain pathways involved in tracking. If a child needs glasses, they should wear them. However, vision therapy is typically needed to address the underlying eye movement and coordination issues.
Eye tracking problems can cause symptoms that look similar to ADHD or dyslexia, such as trouble concentrating or difficulty reading. Some children have both an eye tracking problem and a learning difference. A comprehensive evaluation can help determine what is causing the symptoms.
While professional vision therapy is the most effective treatment, some activities may help at home. These include playing catch, doing puzzles, and reading together with a finger or bookmark to guide the eyes. Your eye doctor can recommend specific exercises based on your child's needs.
