How do eyes work together as a team?

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.


I haven't actually used the optometrist side, so my review is limited to the vision therapy offered.  This office was recommended by my occupational therapist for the treatment of my double vision following a stroke.

Love this location. I had a brain injury accident from day one one. All the team make you feel you still important and hope in the horizon after when the medical system fell you miserably. Dr. Ikeda very professional and very understanding about your issue. Two tombs up.

My husband and I were immediately impressed with Dr Ikeda. I was hit by a car while cycling which caused broken bones and three brain injuries. The brain injuries caused double vision. Dr. Ikeda examined my eyes and got me started on vision therapy with his occupational therapist who specializes in vision therapy.  She (Chris) is absolutely great.  I am impressed with the array of tools used to help recover my binocular vision.  I am doing things I never thought were possible (balance boards etc).  Chris pushes me and keeps me motivated. I really enjoy my sessions with her.  The office staff is always friendly and they have a wonderful appointment reminder tool that makes it easy to keep my calendar up to date. I am happy the rehab center at Little Co. of Mary recommended them!!

The Vision Therapy is handled in a separate office through a different door from the shared waiting room. Chris, the vision therapist, has a wide and varied assortment of tools, equipment and resources to best evaluate and treat most vision issues. After just a few visits, my double vision became easier to control, using exercises developed during the therapy process. It was time well-spent.

I have been coming here since I can remember. I love it here. The staff is so amazing and nice. They explain everything they gonna do and never make you feel rushed. Dr. Ikeda has always been my doctor and I would never want another one. He is the doctor for my whole family and is always asking how everyone is doing. I am also so crazy about picking out my frames and have to try so many and each person who helps me take the time and lets me try them all on. I would never want to go anywhere else! I definitely would recommend this office to anyone looking for a great eye doctor.

This is not for the eye exam but for the frames selection portion. I brought my prescription from Kaiser here with my VSP insurance. The reception staff was very polite and professional.  Manny helped me to pick out frames and explain my coverage.  Very helpful and patient not like the individual at the other place I rated here on Yelp.  I was running late and he still helped me and was not bothered at all.  I am so glad I came here ..........very pleased.

Very professional staff and pleasant.
