Convergence Insufficiency affects your ability to focus on near objects, causing discomfort and symptoms such as double vision and eye strain. Understanding this condition is the first step towards effective vision therapy.
Convergence Insufficiency (CI) is a common eye coordination disorder where the eyes do not turn inward sufficiently when focusing on close objects such as books, tablets, or computer screens. This condition can make reading, writing, or close work difficult and uncomfortable. Many individuals with CI have clear visual acuity on a standard exam yet still struggle with symptoms that affect daily performance and quality of life.
Convergence Insufficiency is defined as the inability of the eyes to work together effectively when focusing on nearby objects. It occurs when the normally coordinated inward movement (convergence) of the eyes is inadequate, so the eyes tend to “look past” the target rather than maintaining perfect focus. This lack of coordinated movement can lead to a constellation of symptoms that may interfere with reading, learning, and other daily tasks.
When the eyes are not aligning properly during near tasks, a variety of symptoms may present. Here’s the thing—these symptoms are not always obvious and can vary in severity, making it important to be aware of what to look out for:
This array of symptoms can easily be mistaken for other conditions, which is why understanding CI specifically is so important for both children and adults.

Convergence Insufficiency is often the result of an innate imbalance in the vergence system—the mechanism that coordinates how our eyes work together when focusing on near objects. Essentially, the eyes use a blend of muscular movement and neural coordination to maintain single vision, and in CI this balance is off-kilter. Researchers believe that an inborn difference in the way the eyes are innervated plays a role in the development of CI.
There are several components involved in normal eye convergence:
For some individuals, CI stems from a natural imbalance in these components, and in others, acquired factors such as fatigue, medication effects, illness, or even head trauma may trigger or exacerbate the condition. It’s also important to mention that many children with CI might not complain of double vision because their brains may suppress input from one eye to avoid the discomfort, masking the full range of symptoms during casual examination.
One of the challenges in detecting CI is that standard eye exams, which often include a 20/20 chart test, might not uncover these coordination problems. A comprehensive evaluation specifically tailored to measure binocular function is essential.
During a detailed exam, our eye doctors look for several key clinical signs:
Because CI can coexist with or be confused with other binocular vision disorders, our eye doctors take a meticulous approach to ensure that the symptoms are due solely to convergence insufficiency and not another condition such as uncorrected refractive error or accommodative insufficiency.
