What is Vision Therapy?

Vision Therapy is a non-invasive, non-surgical treatment option for crossed eyes, lazy eye, convergence insufficiency (CI), eyestrain, blurred vision, double vision, acquired brain injury, and much more.  It can help children get better grades in school, increase self-confidence in teenagers, and relieve headaches and eyestrain in adults working at computer screens all day long.  Vision Therapy can result in success in school, improved performance in sports and coordination, improvement in visual disabilities and learning disabilities.

We Are An Eye Care Practice!

What People Say About 4D - Vision Therapy Testimonials

4D Vision Therapy Testimonials

Testimonials from Parents

"The staff at 4D are amazing and they have helped my children immensely! My children were struggling in school with reading,writing and spelling. They have been going to 4D for about 1 year and the progress is outstanding! I cannot say enough good things about 4D."  Michael K., Parent of 4D Members


"My son goes to 4D vision gym and is doing great! He is always happy to see Erin and do his excersizes. We are very happy and recommend them for your vision physical therapy."  ~ Bill R., Parent of 4D Member


“Vision Therapy has quite simply been the most positive thing in Breanna's life. It's a miracle. We thought she had ADD all these years; her school thought she had a reading comprehension problem. We didn't know what to do. It was her eyes all this time…Even her teachers could see a visible difference in her attitude and confidence within weeks of the therapy.” ~ Mother of Vision Therapy graduate, 15 years old


"To be honest, I regret that I didn't look into it [Vision Therapy] sooner.  I knew that there was something stopping his reading from going forward because he loved it.  But it never occurred to me that it could be a vision issue, and I wish that I had discovered it sooner.  So, I strongly recommend it to anybody considering it." ~ Mother of Vision Therapy graduate


“…She was struggling with her subtraction facts, spelling, found math tiring, and had trouble concentrating on her reading. We started vision therapy and saw remarkable improvement in a short time. She became less distractible and was able to concentrate and focus better on her work.” ~Parents of 4D Vision Gym Member


"Cormac reached a threshold over the summer. He overcame so much difficulty with physical activities. He could now do jumping jacks and jump rope. Swimming became easier, as well." ~ Father of 4D Vision Gym member


“My daughter no longer experiences motion sickness on family car trips; she’s a much better reader…she’s even improved at soccer, which she was always good at, but now she’s even better!” ~ Mother of Vision Therapy graduate, 10 years old


“She is so confident now because she finally feels like she is at the same level as her classmates, can read just as easily as they can, and her grades--they've gone from C's and D's to A's and B's. It's night and day…We can't thank you enough.” ~ Mother of Vision Therapy graduate
