Eye Exam vs. Vision Exam

By Ed

As a former teacher in Citrus County Florida I have a unique background to discuss the difference between an eye exam and a vision exam. I have often said that you can have 20/20 vision but 0/0 vision. What do I mean by that? Well, an eye exam is just that, it measures what each eye sees, whether it is near-sighted or far sighted, or no glasses are needed to provide clear vision. But, taking the exam to a higher level by providing a vision exam we now determine how the eyes work together. A vision exam will determine if there are any problems with eye tracking (moving the eyes quickly and accurately from one word to the other and from the end of a printed line of text to the beginning of the next. It will determine if the eyes focus accurately and in an accurately sustained manner and if the eyes are converging and accurately maintaining alignment. There are many other visual skills that are tested in a vision exam. Any child or adult with reading difficulties should have a comprehensive vision exam (not just an eye exam). These exams often take up to an hour or more and will often find the main cause of a reading problem.
