Understanding Vision

Published on
February 14, 2022

Vision is more than 20/20 eyesight. Great vision relies on more than just healthy eyes. The visual system is made up of both the eyes and the brain - and the way these two parts function together defines the quality of vision.

It is the brain-eye interaction that allows children and adults to function effectively, whether their task is to read words or work on a computer, read a book, catch a ball, walk down the street, play sports or just stay focused throughout the day.

Our eyes are essential tools needed to take in visual information, however our brain takes the images gathered from both of our eyes, combines them, and understands them. It is estimated that between 10-20% of children will have a vision issue that is unrelated to what we normally consider 20/20 vision. A common example is amblyopia which is estimated to impact between 3-6% of the population. Amblyopia is where the brain favors the stronger of the two eyes, and as it develops it shuts of input from one of the eyes. There are over 11 different visual processes, also known as visual skills, used in reading alone. Vision therapy assists those who have vision problems stemming from a delay in the development of a visual process, an injury that has impacted a visual process, or for people looking to optimize their vision for athletic performance. 

What is vision therapy?

Optometric vision therapy is an individualized program that uses an integrated model of visual processing approach that follows evidence-based best practices designed to improve and enhance visual perception and motor skills. It is based on volumes of clinical research from accredited colleges of optometry and published in peer reviewed journals. There are currently established clinical guidelines that encompass the various areas of medically diagnosed visual deficits including but not limited to myopia, strabismus, amblyopia, accommodation, ocular motor function and visual perception motor skills. All of these skills are essential for learning and activities of daily living.

What conditions can vision therapy treat?

Vision therapy is not a replacement for eyeglasses and contact lenses, but it can be used to treat a wide range of conditions that are not addressed with a standard eye exam and prescription. The following list of diagnoses that vision therapy can improve is not exhaustive; however, it offers an idea of how life-changing this corrective modality can be for patients who suffer from these conditions.

  • Brain Injury
  • Strokes
  • Binocular Coordination
  • Convergence Insufficiency
  • Amblyopia (lazy eye)
  • Diplopia (double vision)
  • Strabismus
  • Accommodative Dysfunction
  • Binocular Vision Dysfunction/Strabismus
  • Cranial Nerve Palsy Involving the Eyes
  • Nystagmus
  • Ocular Motor Dysfunction
  • Post Traumatic Vision Syndrome
  • Spatial Disorientation
  • Vestibular (balance) problems
  • Developmental vision delays 

Who benefits from vision therapy?

A vision therapy program can benefit anyone whose vision is not performing at the level they need with standard forms of vision correction such as glasses and contact lenses, regardless of age. Although being treated earlier is always a better choice, vision therapy can also benefit adults. It helps those who have suffered concussions and brain trauma, as well as those with neuro-visual deficits that make it difficult for them to read, write, and learn. Developmental delays in vision highly impact the neuro-diverse populations. Many of our patients include people with autism, downs syndrome, cerebral palsy, and non-verbal learning disorders.  It may take longer for vision therapy to help some populations, but it can greatly improve not only their skills, but also their sense of self.

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.

Claire A.

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.

Jim K.

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!!

Teresa S.

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.

Joe M.

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.

Kayla W.

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.
