Our Approach

How Can We Help You Or Your Loved One?

Redefining Levels of Care


Traditional optometrists answer the questions, “Can you see clearly?” and “Are your eyes healthy?” but eyesight is only one small part of vision. At the Mind-Eye Connection we treat beyond that because some patients need a more comprehensive evaluation of symptoms that might seem unrelated to the eyes.

To that end, we provide 2 distinct levels of care:

1. Developing Mind-Eye Connections:

– Can you efficiently see with ease and comfort?
– Are you effectively using your visual system?

2. Redeveloping Mind-Eye Connections:

– Are the systems connected with your eyes correctly synchronized?

Each person is unique due to differences in genetics, experiences and mind and body control. In fact, it is important to realize that there are crucial links between the body, environment and the mind which determine personality traits.

Even gifted people may have discrepancies among those connections. They may have an over developed mind, but lack social skills (environmental awareness), or they may be gifted in sports (body control) and be poor at academics, etc. Gifted leadership skills are just as important as gifted music and art skills.

At The Mind-Eye Institute we take an individualized approach to every single one of our patients. Each one of our doctors’ skills complement each other, allowing our practice to offer a broad spectrum of services for a variety of populations with various backgrounds. Below is a brief overview of the approach taken by our practice in all these different areas.

1. Developing Mind-Eye Connections

Sensory Processing Assessments

Beyond the traditional eye examination, the Mind-Eye Institute provides Visual Processing Evaluations which determine whether you efficiently see with ease and comfort.  This level of evaluation includes specific testing for ranges of comfort in eye aiming, focusing, eye teaming and evaluates your awareness of and interaction with your environment.

This is helpful for people who have trouble gathering and processing incoming information, for instance those who are lacking in social skills or organization. Typically, patients that would benefit from this kind of evaluation are labeled to exhibit learning difficulties. Symptoms include not being able to easily transition from one situation to another or not being able to visualize concepts while keeping the details in mind. The most common sign observed is avoidance (i.e. avoiding driving, essay writing, reading or sports, etc.)


2. Redeveloping Mind-Eye Connections

Neuro-Developmental Assessments

When conventional eyeglasses are not beneficial, other systems must be considered. Are the systems connected with your eyes corrected synchronized? Here, the linkage among posture, auditory and biochemical systems are analyzed, all which influence eye control and usage.

This level of testing is beneficial for people who have delicately balanced visual systems, where minimal environmental changes are annoying. People who have difficulty in coordination, maintaining attention, or have a delay in development often benefit from this extensive battery of testing which gets to a root cause of a problem, rather than simply addressing symptoms.


Our Research & Expertise

 Autism and Developmental Deficiencies

For almost thirty years, the Mind-Eye Institute has served patients from national and international locations, assessing peripheral eyesight usage in addition to central (20/20) eyesight. Children with special needs or those on the autistic spectrum, benefit from having Mind-Eye eyeglass prescriptions, which help ensure brain signals are being processed efficiently in a synchronized manner. For instance, eyeglass prescriptions determined by using our patented Z-Bell testing help regulate eye-ear connections. Those Z-Bell prescriptions enhance patients' reading, listening and attention in a majority of cases. The individualized glasses create a stable balance between central and peripheral eyesight, as well as auditory and visual localization ability.

Post-Concussion &
Traumatic Brain Injury Exams

Many people suffer from various post-concussive and brain injury symptoms such as photophobia, ocular fatigue, headaches, dizziness, and sleep problems and mood changes. We understand that interactions between the electrical and biochemical pathways in the brain affect physical, physiological and psychological systems. Patients undergo a thorough examination with advanced technology and testing techniques to measure visual performance and visual processing functions. The goal is to determine whether the visual processing systems are in balance with other sensory systems that require perception of space and time, such as auditory localization ability.

A Different Approach to
Learning Difficulties, ADD/ADHD

At our practice, developmental examinations cover much more than how well a patient can see. For example, a child who is diagnosed with ADD, ADHD, CAPD, or developmental delays, may in fact be experiencing these symptoms as a results at least in part because of visual systems dysfunctions. It is important to realize that eyesight is only one small part of the visual system; there are many other visual inputs often not addressed during routine eye exams. Each of the systems develop in a hierarchy, linking with other systems' development. For instance, motor skills and visual skills combine for good hand-eye coordination, or visual and auditory skills combine for reading.

My son has always struggled with developmental delays and academic performance. After spending years working with doctors, interventionist, special ed teachers, reading specialist and tutors, I just had that motherly instinct that there's was something more to my son's struggles. After a lot of research, I found Dr. Z and decided I was desperate for help and would wait the two months to get in, pay the price required and spend the 4 hours in her office on appointment day. I'm here to tell you that it was worth it and I'm just sorry I didn't find her sooner. The outcome was life altering! Just being able to identify that my son has eye tracking issues and has dealt with that challenge the last 8 years of life was enough to almost bring me to tears. We just received his custom designed glasses so only time will tell how effective they are at correcting his issues but after FINALLY finding someone who would listen and could identify his issues was worth more than I can ever express in words. I've already referred a friend and haven't stopped singing her praises since we left her office. Dr. Z is truly an amazing person!!

Several years ago I had debilitating vertigo. It got so bad that when I could walk it was with a walker and much of the time I was in a wheelchair. Several neurologists and MRIs, x Ray's, and several other tests  could not help. I went to Dr Z and was barely able to walk in to the appointment with a walker. I left walking without assistance. She and her staff are miracle workers and the cure was without medication.

How do you properly thank someone who has literally given you your life back? I am thrilled to report that I am having virtually no concussion symptoms at all. I am forever in her debt for helping me regain full functioning. She is absolutely worth the time, travel, and money. I wouldn't have the job I have today, be running my ministry, or enjoying life if it wasn't for Dr. Z, whom God has gifted with brilliance, innovative treatment methods, and a wonderful, warm, caring heart for each and every one of her patients. People are coming from all over the world to see her, because she gets results.

I suffered a traumatic brain injury and struggled with symptoms for eight years, despite trying everything, I am finally seeing steady improvements in the last 8 months since seeing Dr. Zelinsky. I literally have been to 40 doctors and underwent 40 healing modalities but so few really helped. If you want your life back, you owe it to yourself to try this! It works. I wish I had done it sooner, but could not drive or figure out how to get there. A simple flight and Lyft/Uber make that easy now, so don't let that stop you. I am so grateful for her brilliance and her work! She is a godsend!

Like so many others, I was immensely fortunate to have found Dr. Zelinsky by reading The Ghost in My Brain book (by Dr. Clark Elliott). After months of desperate scrambling, going to doctor after doctor seeking help with my debilitating concussion, Dr. Zelinsky was able to quickly identify my hidden visual concerns and address them. She has been compassionate and understanding and provided effective solutions using therapeutic eyeglasses for my head injury. Thank you Dr. Zelinsky for giving me my life back, there are few words to express how appreciative I and my family are for your amazing work!

Much, much more than "just an eye doctor". Dr z has a solid practice in eyes but for anyone who personally struggles with spectrum related issues or who has a child that struggles with autistic spectrum issues, Dr. Z is a god send.  Her innovative and deeply researched approach has produced amazing results for many families. I HIGHLY recommend this practice. Definitely worth a visit!

I am amazed by Dr. Zelinsky - seriously amazed. I am dealing with post concussive symptoms (1 year out) including difficulty with sensory integration. Her Z bell test is mind blowing. I don't get it, but I don't need to. All I know is that I have been wearing lenses for 4 weeks now and the impact has been staggering. I wish I had come to see her sooner and am excited for my next set of lenses. If you have a TBI or PCS, save your $ and see Dr. Zelinsky. I have tried several other therapies: including vision with another Neuro-optometrist and NUCCA and these lenses have yielded the best results. Hands down.

I found that the results provided at Mind-Eye are outstanding!  When it came time for it to be my turn to be seen, I was given the time I needed and not rushed out the door. Dr. Zelinsky is an AMAZING doctor who gives such thorough service and individual care, that you cannot help but tell others about the office visit. The bottom line is Dr. Z will save you money in the long run by solving your mind-eye issues quickly.

Brooke M Illinois

I have been a patient of Dr. Zelinsky's for several years. I brought my older son to see her when he was a few months old and Dr. Zelinsky made a few suggestions to help even out his development (he favored his right side).  She mentioned that the sooner you can correct the problem in a child's life the quicker they can make the change (makes sense to me too).  So needless to say my second child went to see her early on too.  I really trust Dr. Zelinsky's advice.  She is truly brilliant at what she does connecting the mind and eye.

Brooke M
Tiffany S Illinois

I have been taking my son Grant to mind eye connection for 10 years!  Yes, 10 years and I am still truly amazed at how her techniques and bell test still help my son with his auditory processing disorder.  She is ahead of her time and finally after 25 years of research she has done, the US doctors are now inquiring about her bell test. I found a gem in Dr. Zelinsky, she is amazing and has made my son's academic experience a positive one.  So worth going to see this doctor, you will not regret it.

Dr. Zelinsky was able to help my daughter when she was very young with her eye problem where no-one at the time could even diagnose what was wrong with her. My daughter excelled in school and her eyesight just got better and better. I have recommended this place to everyone I know who has an unsolved eye problem. Dr. Zelinsky's patience and personality made it such an enjoyable experience for my daughter.

Leanne V Illinois

Dr. ZELINSKY has come up with a truly revolutionary way of viewing & connecting visual function, auditory function and optimal brain function. We are integrated wholes, not pieces and parts. You cannot effectively diagnose and treat vision problems without realizing that our vision is directly connected with the entire body & brain. What affects one will invariably effect changes in the other.

Carol H Illinois

For the first time in my adult life I can see well with glasses. Dr. Zelinsky did this cool test in which I closed my eyes and tried to touch a bell that they rang. I couldn't touch it... Until they covered my closed eye with a red tented lens. Then my hand went right to the bell... with my eyes closed! It's crazy! Then, Dr. Zelinsky did the same thing with my daughter. Our minds, eyes, and ears are indeed connected.

Augusta started wearing the glasses right away after her visit with you. She noticed an incredible difference in the richness of tones and awareness of notes and measures while listening to music. She remarked within the first day that she felt less clumsy. After about two weeks, she noticed that she no longer experienced headaches as much when she exerted herself physically.

Juli K

After 2 years of continued local treatment, due to a car accident that left me mentally, physically damaged along with post concussion, two amazing friends helped me find my way to the Mind-Eye Institute. Deborah is nothing but amazing, very smart, caring and has unlocked a way to treat injuries through your brain and eyes together. This exam was like nothing I had ever received. Deborah explained what was going on to me and how we were going to start correcting issues by the use of glasses with filters, colors and prisms. It took several treatments and “homework” to help my body heal by using the tools they gave me until my next appointments to treat the whole body. Thank you Deborah, without you I never would have been able to successfully obtain and keep a full time job to get me off disability. You were the one that started the treatments that gave me my life back.

At the Mind-Eye Institute

We understand that interactions between the electrical and biochemical pathways in the brain affect physical, physiological and psychological systems. Visual interventions that alter retinal signaling pathways impact both the electrical and biochemical systems.

Our patients undergo thorough examination with advanced technology and testing techniques to measure their reactions and responses to light entering the retina. With this information, experts at the Mind-Eye Institute determine whether a patient’s visual and auditory systems are synchronized. They consider how light might be manipulated to positively impact brain function and body chemistry. The goal is to find optimal ways of mitigating symptoms that are not improved or resolved through standard approaches.

Specifically, our team offers patients prescriptive eyeglasses, contact lenses or other optometric interventions to selectively stimulate light dispersed on the retina. Individualized lenses can:


  • Maximize patients’ visual performance and visual processing capabilities and create a stable balance between hearing and visual localization.
  • Improve patient perception of the surrounding environment in order to modify behavior and enhance communication skills.
  • Help rebuild brain pathways or develop new pathways that enhance a patient’s ability to learn, understand and interact normally with others.

'Dr. Zelinsky Is Renowned'

~ Norman Doidge, M.D. & Clark Elliott, Ph.D., Dr. Patrick Quaid and Patricia S. Lemer praise her accomplishments:

"Zelinsky fit Elliott with a series of eyeglasses designed to improve the perceptual damage that made his life so difficult... Getting fitted for Zelinsky's eyeglasses is like no eye appointment you've ever had... Now, Elliott says, he is almost entirely symptom-free, able to problem-solve, multi-task and find his way easily — all abilities he lost in the auto accident in 1999. When he put on his Phase VI glasses he felt something that he hadn't felt for years: "I felt normal."

Review: 'The Ghost in My Brain'
- The Chicago Tribune

"One brilliant Chicago-area optometrist I know, Deborah Zelinsky OD, FNORA, FCOVD, has developed a unique, patented, easy-to-administer evaluation called the Z-Bell Test. This test measures the efficiency of integration between visual processing and listening....A 2014 study at Vanderbilt University found that children with autism do not synchronize their seeing and hearing...I have watched Dr. Zelinsky administer this test to disbelieving colleagues, who were astounded by its accuracy and results...Over the past two decades, the Z-Bell Test has become internationally recognized by the scientific community.”

- Patricia S. Lemer, Licensed Profesional Counselor (LPC)

"I visited Dr. Zelinsky, and she showed me how she can use optical lenses to alter sensory filtering, by directing light to different retinal cells and brain circuits. This can influence activity in the brain and the hypothalamus to better regulate body chemistry, sensory integration, and even some auditory processing. [Dr. Zelinsky] works frequently with patients working with learning and cognitive disorders as well as TBIs."

- Norman Doidge, M.D.

"I was delighted to have Dr. Zelinsky personally contribute to the book. Her wealth of knowledge in the area of visual development and visual processing is widely known, not just through her contribution of eye-care to the author of “The Ghost in My Brain”, but also via her Mind-Eye Institute and the lectures and training their provide. Dr. Zelinsky is not just college and a friend, but also a valued member of the neuro-optometric community and an invaluable bridge to other allied professions treating brain injuries. Her contribution to the book is deeply appreciated."

- Dr. Patrick Quaid, MCOptom, FCOVD, PhD
