The Teamwork of the Eyes

In order for the eyes to work properly together as a team, both eyes must be focused on the exact same target. This is the ideal situation when these visual signals get sent back to the brain where the image gets processed as a clear picture. Think about the eyes as if each one is a camera that takes a picture and sends it back to the brain to get processed, or as if the brain is where the film gets developed. If both images from each camera are going to get processed together, we need both cameras, or eyes, to be focused on the exact same spot.

Convergence Insufficiency

There is a condition called convergence insufficiency which occurs when both eyes are supposed to come together to focus on a near target but the eyes are not coming together enough. For example, if someone with convergence insufficiency is trying to read a book, they won’t receive the most clear image possible because one eye might be pointing exactly on the target in the book, but the other eye might be pointing more outwards.
Using the camera metaphor, in convergence insufficiency, the cameras are not broken. There still is an image being received from the right camera and another image being received from the left camera. However, when these images go to the brain for processing, they do not perfectly overlap to cause the ideal clear picture and instead there is a misalignment between the images.

Common Questions

In convergence insufficiency, there is often a subtle mismatch between the images that the brain is receiving from each eye. This misalignment is profound when trying to read a small font on a page. However in contrast, the mismatch that occurs in convergence insufficiency is not so noticeable when looking at images which is the case of our example, when a child is playing video games. In addition, convergence insufficiency does not have a significant impact when looking at large print which is usually the case for very young children who mostly read using a big font. The complaints of difficulty due to convergence insufficiency is most common when trying to read fine print.

What Is Convergence Insufficiency?

Convergence insufficiency is a condition when the eyes are not working together properly as a team. It’s when one or both eyes are not properly moving inwards when trying to focus on a near object. This makes it hard to focus or read and can lead to blurry or double vision. It can also cause headaches or eye strain.

Such a nice optician. My grandson is only 4 and needs glasses. We were so sad, but he explained the issues, and we will follow up as he suggested.

I had such a good experience with the clinic. Very friendly staff and doctor, did not have to wait for long to be called, and was treated respectfully. Thanks, American Family.

Dr. Zurcher has gone above and beyond what any other eye doctor has ever done to figure out what is going on with my eyes. Very happy with American Family Vision.

Family Vision Clinic changed our lives! My daughter was frequently car sick, and she was getting headaches every day, often painful enough that they brought her to tears. We saw a string of doctors and therapists, but we made no progress. Finally, we found Dr. Levi Zurcher and his eye therapist Rain. After ten weeks of eye therapy my daughter no longer gets headaches, and she no longer gets car sick. Daily tears are a thing of the past. I really can’t say enough about this clinic. It was fascinating to watch Dr. Zurcher work. For the first time, someone who knew what they were doing was intently studying my daughter, really trying to figure out all of her eye issues, and his therapist Rain is one of the most patient and lovely people that I’ve ever had the good fortune to meet. We’re finished with eye therapy—yay!—and I have switched to American Family Vision Clinic for all of my family’s other eye health needs.

Very professional, yet kind and helpful. They do what they can to make the appointment comfortable. I was running a bit late, I made sure ti call. They were able to switch me with a patient who was already there, they treated me with respect, and helped my son have confidence by getting him the eye care he needed that day. Thank you so much! Would recommend to anyone. It's a blessing that they care enough to work with people who have all different types of insurance from work to state coverage.

The staff is friendly. The Doc is very knowledgeable. The office is family friendly and everyone is so patient with the little ones.
