Strabismus & Amblyopia

Many adults believe that vision training is only meant for children. While it’s true that a younger, more adaptable mind has a definite advantage throughout the vision training process, the benefits that many adults receive from vision training are incredible. In fact, because adults are typically more invested and better able to understand the vision training process, they tend to internalize therapy faster which leads to great results.

Strabismus, also known as an “eye turn” or “cross-eye” is a condition caused by the inability of the brain to point both eyes in the same place in space. One eye may be straight ahead while the other may point up, down, in, or out. The eye turn may happen all the time, only when looking at certain distances, or only when tired. A person with strabismus may experience double vision, headaches, difficulty with eye-hand coordination and depth perception, squinting or closing one eye, or tilting or turning their head to focus

Amblyopia, commonly known as “lazy eye”, is reduced vision in one eye, even with glasses or contact lenses. A “lazy eye” is not actually lazy! When a person has difficulty using both eyes together as a team their brain may begin to actively ignore visual sensory information from one eye to avoid confusion or double vision.

Amblyopia can be caused by strabismus, a significant amount of uncorrected farsightedness, nearsightedness or astigmatism, or a cataract or tumor. A person with Amblyopia may experience headaches, difficulty focusing, eye strain, or difficulty with eye-hand coordination and depth perception.

Treatment of Strabismus and Amblyopia

Vision rehabilitation and training teaches the brain how to use both eyes together and point them at the same point in space. Neuroplasticity research has shown that through the meaningful visual experiences taught in vision training, individuals of any age can learn to use their two eyes together as a team.

Frequently Asked Questions

Vision development and/or rehabilitation is a progressive program of procedures performed under the supervision of an optometrist. Programs are individualized to meet the specific needs of each patient. Most programs are conducted with weekly one-on-one in-office visits with a certified vision therapist, in addition to daily practice at home.

Not all optometrists are trained to assess functional vision. At a typical eye health examination, your optometrist will examine your eyes, looking for any early warning signs of diseases such as glaucoma, age-related macular degeneration, cataracts, diabetic retinopathy, and others. In most cases, the eyes are found to be healthy. Your optometrist will also measure your visual acuity to determine if you need glasses or contact lenses in order to see clearly. 

At a binocular vision or neuro-optometric assessment, your functional optometrist will provide in-depth testing to look at developmental or functional vision problems. You may have 20/20 acuity, but not be able to use your vision effectively or efficiently. When your functional vision is reduced you may experience a variety of symptoms such as headaches, difficulty reading, eye pain, difficulty with comprehension, or concentration. Your functional optometrist will look at the whole picture of how you use your vision in your every day life.

Initial assessments cost $444 + tax and may be covered by your insurance plan. 

At your initial assessment, your optometrist will determine a treatment plan designed to meet your individual needs. There is no standard length of treatment, or standardized program. Once a program has been designed specifically to meet your needs, your vision therapist will provide an approximate cost and length of the prescribed program. Regular follow-up examinations with your optometrist will determine your progression through the program.

Every patient begins with a comprehensive Initial Assessment. Based on the findings of the Initial Assessment, your Doctor may prescribe lenses, filters, tints, prims, further assessments, and/or vision training.

Vision therapy uses the science of neuroplasticity to teach the brain and the eyes how to work together. It used to be widely believed that our brains became “fixed” after a certain age. It is now known that neuroplasticity is a lifelong process. While young brains are highly responsive and adaptive, older brains are also capable of change and growth! Even in cases of brain damage, the human brain shows a remarkable capability to adapt and grow. How we use our vision is a learned process. Vision therapy teaches the necessary skills to use our brain and eyes together effectively and efficiently.

Yes! There is a growing body of research and literature backing the science of neuroplasticity and vision development & rehabilitation. At you can access some of the very latest literature and research papers.

Yes! Success depends on an individual’s motivation, cooperation, and engagement with their program. At Fretz Neuro Vision our passion is to help you unlock your full visual potential. Open communication with your vision therapist is a vital part of this process. If you are presented with a roadblock that is affecting your motivation or ability to fully engage in your program, we are fully committed to working together to identify the barrier and come up with a creative solution.

Optometrists providing vision therapy spend years in post-graduate and continuing education. Specialized training is ongoing throughout their entire lifetime. Some optometrists will opt to complete a fellowship, becoming board certified in vision development, vision therapy, and/or vision rehabilitation.

All of our vision therapists have completed the PVTAP (practical vision therapy accreditation program) through Vision Therapy Canada. Maintaining accreditation requires ongoing CE (continuing education). 

Each person and program is unique. Typical vision therapy programs take 10-60 weeks to complete. Your progress will be closely monitored by regular check-ins with your optometrist. Progress will be reevaluated during each check-in.

Yes! Once visual skills are fully integrated and being used in everyday life, you will continue to see improvements, even after your program of vision therapy is complete. Your optometrist will continue to monitor your progress over the year following your program. If your optometrist finds you are not fully using the skills you learned during your program, they will make recommendations to get you back on track.

20/20 refers to visual acuity. This is the ability to clearly see black letters on a white background at 20 feet. There are not many situations in everyday life where we sit still in a dimly lit room, staring at a stationary chart with letters. In life, our eyes are moving, our bodies are moving, and the objects we are looking at may be moving. Vision is dynamic! The goal of a program of vision therapy is to teach you how to coordinate your brain, eyes, and body, so they can all work together optimally in all conditions!
