Research, Results & Medical Studies Have Proven
Vision Problems Can Look Like
Learning Difficulties

Children don't know how they are supposed to see - so they rarely complain. The only way they can show you there is a problem is with their behavior. Most of the children we see in our office that struggle with reading have passed vision screenings.
Your child could see "20/20" and still have an eye coordination or eye tracking problem interfering with reading and learning.
Is it ADD, Dyslexia or another Learning Disability?
Or, is it a correctable vision disorder?
As a parent, how can you tell the difference?

When a vision problem is at the root of a child’s struggles
with reading and learning, the signs are very easy
to see – when you know what to look for.
Does your child:
Each of these can be a sign of a possible eye coordination, eye tracking or eye movement problem.
For example, eye coordination problems can make it look like the words are moving on the page or appear double or blurry. When this happens, it can be very difficult to remember what you have read.
Being able to see "20/20" is just one of 17 visual skills required for reading and learning...
Vision screenings in school and at the pediatrician's office usually only test how well your child can see the letters on the eye chart from a distance of 20 feet (20/20). Even though there are 17 different visual skills required for reading and learning, most people think, incorrectly, that 20/20 is "perfect vision." As a result, vision is incorrectly ruled out as a possible cause for their child's struggles with reading and learning.
Dr. Cantwell and his staff specialize in treating children who suffer from vision problems that interfere with a child’s ability to read and learn. Research shows that up to 80% of learning is dependent on vision. As such, an undiagnosed vision problem may have a profound effect on a child’s education.
Many of the symptoms of vision problems, such as difficulty concentrating on classwork, daydreaming, or poor/slow reading are similar to those symptoms displayed by children affected by learning disorders. Vision problems that interfere with learning and reading can easily be overlooked or misdiagnosed as learning disabilities, such as ADD/ADHD, Dyslexia or LD.
If you find that you or your child have 3 or more symptoms above, it is recommended that you schedule an appointment for a full development vision evaluation.
While your child does not appear to have many of the above signs, if your child has attention problems, struggles with reading or has an eye turn (Strabismus) or a lazy eye (Amblyopia) we recommend you schedule an appointment with Dr. Cantwell.
If your child is doing fine, it is recommended that school-age children have a routine eye exam by an optometrist once a year.
