​Comprehensive vision exams

A comprehensive eye exam is the starting point for resolving most vision problems. At eye-brain connection, our eye exams include all the required elements such as visual acuity assessment, pupil responses, a measurement of eye pressure, a determination of the prescription for glasses for both distance and near, field of vision assessment, a check for eye alignment, color vision testing when appropriate and a visual inspection of the front, middle and back of the eye.

Our in-depth examination allows us to determine your prescription for clear eyesight and to rule out issues that relate to ocular pathologies such as a retinal tear, cataracts, or glaucoma.


At eye-brain connection, this exam gives us the initial data to pursue more sophisticated investigation into how your eyes can influence how your brain functions.



Contact lens exam


After a comprehensive eye exam, you may want to add a contact lens exam and fitting.


A contact lens exam includes a tear assessment, measurement of the curves of the front part of your eye, and a selection of the appropriate lens material including water content, type of plastic and rate of disposability for your health and lifestyle. Your exam will address how your contact lens fits your eye.


"Fit" is actually a word used to determine how the lens "breathes" and interacts with the tissues of your eye. The fit of the contact lens matters to eye health as well as vision and comfort. 



Functional binocular vision exams


A functional binocular vision assessment aims to investigate the strengths and weaknesses of how the two eyes work together in focusing, eye teaming and eye tracking. 


The way your two eyes work together is not an innate skill, it is learned skill. As such, it can be modified by light, retinal stimulation and exercises. The reason for problems in tracking, teaming and focusing has much less to do with eye muscle strength and much more to do with neurological connection between the eyes and brain.


These eye-brain connections are tested by applying a stress to the system being evaluated, measuring where the system becomes dysfunctional (double or blurry or both) and then reducing stress until normal function is regained.


This type of testing gives tremendous insight into how much effort a person has to give to basic vision tasks instead of using that effort for awareness, comprehension, cognition and speed of processing.

Basic vision skills/tasks should be subconscious, immediate and accurate. This frees up the mind to use it’s executive powers of reasoning, decision-making and execution of movement in the most efficient ways possible. Addressing the eye-brain connection can improve your learning, balance and coordination and you can have a better quality of life through better visual processing.




Not all eye problems stem from eye health issues and not seeing clearly.


Balance, motion sickness, coordination problems, sensitivity
to peripheral vision and sound, sensory integration disorders
and learning disabilities can all happen to a person
who has 20/20 eyesight and healthy eyes.

All of these issues have to do with the eye-brain connection.




Neuro - optometric vision exam


Neuro-optometry is at the heart of the eye-brain connection. It is the exploration of which pathways from the eye to the brain are dysfunctional and the ways to maximize your potential with those dysfunctions. It is important to know that there are many neural pathways from the eyes to the brain that do not have anything to do with central eyesight.


The neuro-optometric exam builds on the comprehensive eye exam and the binocular vision exam. In this exam, a more comprehensive review of your visual perception and overall body systems are performed through extensive symptom survey forms.


In addition, we perform tests that indicate how fragile your sense of balance is, how well you can spatially locate objects and sounds, and how accurate is your sense of your center (your midline). Strengthening neural connections with activities and brain nutrients are also keys factors to address.

All of this data is used to create a personalized pair of glasses that addresses the symptoms of an inefficient eye-brain connection.


The people most likely to benefit from these specialized glasses are those people who have a small range of tolerance to visual stress and a narrow band of comfort in their visual perception.


The most common conditions associated with narrow ranges of comfort and tolerance are: Traumatic Brain Injuries (TBI),strokes,learning difficulties, ADD/ADHD,motion sickness,and sensory processing disorders.



Color fields


A color field is a measurement of your peripheral awareness to color as compared to your central perceptions of the same color.  It is recorded on an instrument called a stereo campimeter which holds a large piece of graph paper, with a central fixation target about 25 cm away from your eye. You look at the central fixation target through a pair of mounted weak magnifying lenses, one eye at a time.

The examiner has you look at a 1mm dot of color attached to a wand that they bring from the periphery to the center of your field of vision. When you see the colors look identical, you let the examiner know and a mark is made on the graph paper in 8 different meridians. Connecting the marks shows the extent of your color field. Green, red and blue are the colors used to plot the different fields.   

The size of the fields is of great significance. The smaller the field, the more symptoms a person has cognitively, emotionally, optometrically, and physically. If your color fields are small you most likely will have comfort issues with visual perception and awareness. It is not unusual to find collapsed color fields of 10 degrees or less.

The measurement of the color fields leads to a selection of the colors used in optometric phototherapy.


The color fields are a metric to gauge the change in your physiology, awareness, and eye exam findings as the result of optometric phototherapy.


It is simple but profound to note the effect of different frequencies of light on our physiology. By using optometric phototherapy, see below, you can attain a remarkable opening up of your color fields with attendant changes in your symptoms.


Color therapy, Syntonics, optometric phototherapy

Optometric phototherapy, Syntonics, or color therapy all are words to describe the process of shining of differing frequencies of light into the eye to create balance in your nervous system.


Many factors go into the decision of which light frequency combinations are optimal for your particular situation. Optometric findings, emotional status, health history, body type, and color fields are all combined to arrive at a prescription for light therapy.


A typical program involves renting a light machine and looking at the light over about a month's period of time. Most often, you sit quietly in a semi-darkened room and look at a color for 10-20 minutes 5 consecutive days in a row, followed by 2-3 days off. This cycle is repeated twice and then another color field is charted to see if progress is being made. Sometimes an adjustment of the frequencies is made at this visit. Then, another two rounds of 5 days on and 2 days off. A final color field is charted to assess progress.



Developmental Vision Exams


When evaluating a school-aged child who is having learning difficulties, Dr.Trinka must make the determination of whether the problem lies in visual efficiency (tracking, teaming and focusing), visual development, or both.


Visual development are the stages that a child goes through as they mature from an infant to a child to a teenager. Given the normal progression of development, a child can easily tell which is right and left on their body and project that into space. They can easily remember things that are visually processed.


They can easily pick out a simple figure in a complex background. And, they can recognize a form no matter if it is upside down or reversed right and left.They can also make their hands do what their brain wants, guided by their eyes.


Problems in these areas lead to poor handwriting, slow reading, inability to remember what is read,

poor comprehension and struggles in school among other things.


A developmental exam investigates each of these areas with standardized tests that compare the child's performance with their grade norms. In this way, Dr.Trinka can decide which areas are not developed and provide specific therapies to help strengthen them.



Pre- and Post-Operative LASIK and Cataract Exams


A critical role in the decision to have LASIK or cataract surgery is a proper consult. An optometrist is the first professional you will seek to improve your eyesight in this way.


There are certain guidelines that guide Dr.Trinka in helping you decide whether or not a surgical option is the best choice for you. One of the largest factors is weighing the problems with your eyesight in daily life versus the risk of a surgical procedure. With LASIK and cataract surgery, the risks for complications are small yet real.


The comprehensive eye exam will uncover the need or appropriateness for a surgical option. A careful discussion of risk and benefits follows.


Dr.Trinka can refer you to surgical teams he has worked with for over 20 years. Pending approval from the surgeons, an appointment is made for the procedure and the first day post op visit is made at our office. Subsequent followup visits are then scheduled to complete the post operative care.

 "In addition to a complete workup, he performed some simple but very elegant tests that I had never seen before, and pinpointed my problem of vertical doubling/axis rotation of both eyes in different directions.  When he inserted trial lenses in a headpiece that I could explore with around the office, my eyes welled up!  I could see! I could focus on the printed word at all distances!"     -Carrie T.
