Functional Vision Problems can affect people of all ages

No matter who you are, functional vision problems affect what you do.  And no matter what age you are, optometric vision therapy can help!

Most people are familiar with typical eyesight screenings. They are aware of the Snellen eye chart (20/20 test), which tests your ability to see objects clearly at a set distance. But functional vision is different.

Undetected by typical vision screenings, many educators and doctors are unaware Functional Vision problems even exist. Vision Therapy can help correct Functional Vision Problems by retraining you or your child’s visual system to work properly.  

Children and Adults can be Treated with Vision Therapy!

The Vision Therapy Center provides optometric vision therapy to correct functional vision problems in children and adults. Optometric vision therapy is the use of lenses, prisms and eye exercises and activities prescribed by a developmental optometrist. The goal is to develop the visual skills so the visual system is working easily and efficiently.

A Functional Vision Problem Can’t Be Detected by Typical Vision Screenings

Snellen Eye Chart

According to the American Optometric Association, 1 in 4 children has an undetected vision problem that affects their ability to learn. They’re “undetected” because typical school vision screenings only screen for acuity, or seeing clearly. They don’t test such skills as:

Eye teaming - Tracking

Focusing - Visualization

It’s why many children and adults who have 20/20 eyesight actually have a Functional Vision Problem! Children lacking in these critical visual skills will have problems reading, writing and may even have behavioral issues. They may experience symptoms such as headaches, sore eyes, and short-attention spans.

Only a Functional Vision Exam will Diagnose a Functional Vision Problem

It tests specifically for the Functional Vision problems typical screenings miss. To find out if this type of exam is needed, scroll up the page and take our Vision Quiz to see if you or your child has the symptoms of a Functional Vision problem. Or, click on the button below to schedule an exam.

Vision Therapy helps Children and Adults Develop the Visual Skills Necessary for Good Vision


How does Vision Therapy work? Using optical devices, patients engage in activities that help the visual system correctly process the visual information that the brain receives from the eyes. A person will practice these activities at home for approximately 20 minutes a day, 5 days a week. These activities at home are combined with weekly office visits, and a typical program lasts 6-9 months. After that, the functional vision problem should be corrected.
