Testing for More than 20/20
Our vision exam tests much more than just the clarity of your eyesight (referred to as 20/20 eyesight).  A complete vision exam evaluates many important visual skills.  We evaluate depth perception, eye movement skills, ability to focus easily from near to far to near, focus endurance for near-centered tasks, color vision, visual fields and more, if necessary.  In addition, the health of your eyes, inside and out, is carefully evaluated for such problems as cataracts, glaucoma, circulatory problems, hypertension, diabetes, etc. 

Vision Exams for Children
Children should have a complete vision exam at the ages of 6 months and 3 years.  Thereafter, they should have complete visual evaluations on a yearly basis with the first evaluation occurring the summer prior to entry into Kindergarten. 

Vision Exams for Adults
A thorough vision evaluation and follow-up care on a regular basis are very important for early detection and treatment of eye health problems and for prevention of vision problems created by or aggravated by today's academic and professional demands.  Our modern world demands more from our vision than ever before.  In fact, 80 percent of all school learning tasks require close-up vision.  Adults in our hi-tech society constantly use their near vision at work and at home.  Your vision should be evaluated EVERY YEAR or more frequently if symptoms of vision problems occur.
Helpful Vision Guidelines for your Family

Vision Therapy is also referred to as:

  • Visual Training
  • Vision Training
  • Visual Therapy
  • Optometric Vision Therapy (not entirely accurate)
  • Neuro-Optometric Rehabilitation
  • Behavioral Optometry
  • Developmental Optometry

Vision therapy is a type of physical therapy for the eyes and brain -- is a highly effective non-surgical treatment for many common visual problems such as lazy eye, crossed eyes, double vision, convergence insufficiency and some reading and learning disabilities. Many patients who have been told, "it's too late," or "you'll have to learn to live with it" have benefited from vision therapy.

In the case of learning disabilities, vision therapy is specifically directed toward resolving visual problems which interfere with reading, learning and educational instruction. Optometrists do not claim that vision therapy is a direct treatment for learning disabilities.

What is involved in a Vision Therapy program?

Vision therapy is --
  • a progressive program of vision "exercises" or procedures;
  • performed under doctor supervision;
  • individualized to fit the visual needs of each patient;
  • generally conducted in-office, in once or twice weekly sessions of 30 minutes to an hour;
  • occasionally supplemented with procedures done at home between office visits ("home reinforcement" or "homework");
  • depending on the case, the procedures are prescribed to:
    • help patients develop or improve fundamental visual skills and abilities;
    • improve visual comfort, ease, and efficiency;
    • change how a patient processes or interprets visual information.

Vision Therapy Is Not Just Eye Exercises

Unlike other forms of exercise, the goal of Vision Therapy is not to strengthen eye muscles. Your eye muscles are already incredibly strong. Vision Therapy is not to be confused with any self-directed self-help program of eye exercises which is or has been marketed to the public.

In-office Vision Therapy is supervised by optometric vision care professionals and many types of specialized and/or medical equipment can be used in Optometric Vision Therapy programs, such as:

  • corrective lenses (regulated medical devices);
  • therapeutic lenses (regulated medical devices);
  • prism lenses (regulated medical devices);
  • optical filters;
  • occluders or eye patches
  • electronic targets with timing mechanisms;
  • computer software;
  • balance boards (vestibular device)
  • visual-motor-sensory integration training devices
The first step in any Vision Therapy program is a comprehensive vision examination. Following a thorough evaluation, a qualified vision care professional can advise the candidate as to whether Vision Therapy would be appropriate treatment.


The comments below are a very good example of the response we receive following Vision Therapy for young people who are active in sports programs in their community and/or school.  Sometimes it's difficult to spot a vision problem in your child, which is why it's very important to schedule eye exams at an earlier age so your child can participate more effectively in school.   
Lindsey is so much happier after Vision Therapy. She has been really struggling in school, but we are watching a turn around this year. Lindsey is beginning to love reading. She used to struggle to finish a book, but now she is reading two books a week. Her reading comprehension is improving by leaps and bounds!

Lindsey has always been very active in school and sports, but I've seen such a change in her spirit this year. She's more confident of all her abilities. She is much more coordinated in her sports. She almost always missed the goal in soccer, because she couldn't line the ball up with the goal. That is not a problem anymore. She is doing really well right now in basketball. It is so nice to have my happy child back!

Both of my girls have benefited greatly from Vision Therapy. We were skeptical at first, but I'm so glad that we had both our girls treated. They are on their way to success in all walks of their lives.

     - Comments from Lindsey's Mother

If your child exhibits any of the following behaviors, he or she may be suffering from a problem with convergence and/or adequate visual function and/or visual perception. These visual problems can contribute to learning disabilities or, in some cases, can be mistaken or misdiagnosed as learning disabilities.

Your child . . .

  • Seems bright, but struggles with reading.

  • Fatigues quickly when reading, with frequent signs of frustration.

  • Is unable to sit still; cannot stay on task for any length of time.

  • Reverses words, numbers or letters.

  • Has difficulty remembering spelling words.

  • Is disorganized and frustrated when studying visual information.

  • Frequently loses his place, skips words or whole lines of text.

  • Has poor reading comprehension.

  • Has difficulty copying from the board or a book, has sloppy handwriting.

  • Medication or tutoring has not been successful in improving school performance.

  • Has been labeled LD (learning disabilities), ADD, ADHD, or dyslexic.

What is the treatment strategy when it is determined that a defect in visual function is present?

When indicated, a personalized and interactive Vision Therapy program can be administered under supervision. Each program is individualized to meet a child's specific visual needs. This type of therapy is short-term and goal-oriented.

Does Your Child Have a Vision Problem That Might Be Interfering With School Performance?

If your child is not working up to potential in school there is a strong possibility that a vision problem might be present. According to experts, almost 50% of children with learning difficulties have vision disorders. In most cases these problems can be successfully treated leading to improved learning and better grades.

You can determine whether your child might have a learning related vision problem by completing the following questionnaire.

Print Out the form below and then for each question, CIRCLE the appropriate answer.

1. My child has difficulty concentrating and paying attention.
1. never 2. sometimes 3. often
2. My child requires a lot of time to complete homework.
1. never 2. sometimes 3. often
3. My child complains of blurred vision, or double vision when reading.
1. never 2. sometimes 3. often
4. My child complains of eyestrain or headaches when reading.
1. never 2. sometimes 3. often
5. My child loses his/her place when reading or skips words or lines.
1. never 2. sometimes 3. often
6. My child has difficulty copying from the board.
1. never 2. sometimes 3. often
7. My child has difficulty with handwriting.
1. never 2. sometimes 3. often
8. My child reverses letters, numbers or confuses similar words.
1. never 2. sometimes 3. often
9. My child becomes tired or sleepy after short periods of time or his/her reading comprehension deteriorates with time.
1. never 2. sometimes 3. often
10. My child has struggled in school.
1. never 2. sometimes 3. often

For each question your child's score will be 1, 2, or 3.

Add up the total score for the ten questions and compare it to the guidelines below.

Score What That Score Means
10-12 Your child probably does not have a vision problem interfering with school performance.
13-18 Your child may have a vision problem interfering with school performance.
19-30 Your child almost certainly has a vision problem interfering with school performance.

If a child has a score greater than 12 it is strongly suggested that an evaluation be done testing those aspects of vision that might be contributing to learning difficulties. If a problem is detected, a Vision Therapy program may be recommended to eliminate the vision disorders.
