Binocular vision and why two eyes need to work together

Published on
September 27, 2022

A significant percentage at least 10% to 20% of the population suffers from binocular vision dysfunction, yet almost no one is aware of it. A simple eye exam does not detect BVD due to slight vision misalignment, making things even more complicated.

What is binocular vision?

The term binocular vision simply refers to seeing with two eyes at the same time. Our brain cannot see in 3D and judge distances and depth without two eyes, and using two eyes at the same time is much better than using one eye at a time, as the combined image from two eyes has a higher quality than that of a single eye.

Why is testing for binocularity important in an eye exam?

The majority of people are surprised when they are tested at our practice for binocular vision during an eye examination. We include this testing because using two eyes together is so important for visual function, specifically it is needed in order to perform daily tasks such as driving, reading, walking, and so on, we rely on our binocular vision.

Testing for binocular vision is an essential part of our eye examinations. In some cases, the binocular system itself is ignored during an eye exam and the eye doctor is only concerned about whether you can see or if you have any refractive errors that require glasses or contact lenses. As a result it may be difficult to get used to certain glasses or contact lenses because no effort was made to determine whether there was a binocular vision problem.

Our eye doctors get referrals from other optometrists not because they aren't capable themselves, but because they don't do additional tests that our vision therapists or behavioural optometrists do, such as determining how your binocular vision is performing.

How is binocular vision dysfunction treated?

Wearing prescription glasses or contact lenses will not solve this problem. Generally, vision therapy and specialised glasses are used to treat inadequate binocularity. The purpose of vision therapy is to develop efficient visual skills and processing by utilizing a sequence of activities prescribed and monitored by behavioural optometrists and vision therapists.

Testimonials


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.
