Everything You Need to Know about
Convergence Insufficiency

Normally, your two eyes work as a well-coordinated team to help you focus on objects that are nearby and far away. Convergence insufficiency is a vision problem that occurs when your eyes do not work well together to focus on a nearby object. This vision problem can cause several symptoms when you are reading or doing other work at a close distance. Fortunately, vision therapy as provided by developmental optometrists and vision therapists relieves symptoms associated with convergence insufficiency.

Our Yakima and Richland Developmental Optometrists Discuss Convergence Insufficiency

When you look at an object close to your face, both of your eyes should turn inwards to focus on that object. In patients with convergence insufficiency, it is difficult for them to pull their eyes inward to focus on things up close such as words in a book.

Symptoms of convergence insufficiency include blurred vision, words that seem to move off the page when reading, double vision, headaches and difficulty concentrating. A person with this condition may squint or close one eye to read or focus on nearby objects.  This may occur even if the patient has 20/20 vision.

Convergence insufficiency is almost always not caught in a normal school vision screening or the vision screening done at a pediatrician or other medical office.  Even in a routine vision exam by an eye doctor, it is often missed.  Vision Therapy Clinics have eye doctors that specialize in convergence insufficiency and other binocular disorders, called developmental optometrists.  At Washington Vision Therapy Center, we are a referral center that over 100 doctors in the area refer to for convergence insufficiency and other vision conditions needing vision therapy.  If you are concerned that you or your child has vision therapy, you can ask your doctor to refer you or feel free to call us directly with your questions.  

Vision Therapy is Effective Treatment for Convergence Insufficiency

Vision therapy for convergence insufficiency helps ensure that both eyes turn inward when you focus on an item near. This therapy is done by trained vision therapists under the direction of specially trained developmental optometrist, and may include the use of glasses, prisms, and exercises aimed at helping the individual improve the coordination of the eyes so that they can effortlessly focus the eyes at near.

The American Optometric Association and the College of Optometrists in Vision Development recommend vision therapy to treat convergence insufficiency. Results from the Convergence Insufficiency Treatment Trial, a study sponsored by the National Institutes of Health and published in the Archives of Ophthalmology, show that 75 percent of pediatric participants who received vision therapy by a trained vision therapist had fewer and less severe symptoms associated with reading and doing other near work.  At Washington Vision Therapy Center, we have a history of even higher rates of success, most likely because we can tailor the therapy to the patient and not have to deal with the rigors of a double-blind, placebo-based, multi-center treatment trial.
