Vision problems can indeed massively impact one's quality of life. I can speak on that from experience. When I was a baby, I never crossed my eyes when trying to look at my own nose. Not because I wasn't interested in my nose, but because it turned out that I was physically unable to control my eye muscles well enough to do so. I still can't cross my eyes, even after decades of doing eye exercises. Thanks to an optometrist like Cameron who was interested in vision development, I finally got help for my vision challenges when I was five years old. Noticing real improvement took three years of hard work every day doing the eye exercises that he prescribed for me and returning to his office to try different glasses to correct my nearsightedness and to check my progress in the physical therapy. Yes, it was physical therapy..... for my eyes. We usually think of PT for injured arms or legs or things like that, but part of what I needed (and what far more people than we realize need) was PT for my eye muscles. He found that the rectus muscles that control eye movement from side to side were too weak, especially in my left eye, to help me track movement and to focus on objects. I also had some weakness in the up and down moving muscles as well. My right eye was doing most of the work and it wasn't as good at it as it could be either. He had me use the Brock String (beads that you can slide to different distances on a string, and they'll stay put until you move them again), Stereoscopic 3D Therapy, pendulum swings and others. It took a lot of determination, self-control, and encouragement from my family for me to get through the sweat, tears and frustration of doing those exercises daily, but I'm now glad that I did. Because of his help, I was finally able to read and write to some degree by the time I was eight and able to read fluently by the time I was twelve. It got so I went from avoiding reading and asking people to read to me, or listening to books on tape, so that I could memorize the stories to becoming an avid reader and frequent visitor to the library. Cameron explains ways that our vision problems can impact our reading so well in this video! It took a long time, a ton of concentration and a lot of practice for me to stop seeing pages like his video within the talk shows. I love that video where the sensor can detect what the patient's eyes are actually looking at on the page! I've never been able to explain to people what I see when I'm trying to read very well, but this video comes quite close to it. In addition to getting lost on the page because my eyes accidentally focus on the wrong spots at the wrong times, I also see the words slide from side to side and sometimes, I see two lines of the same text overlapping each other. It's not as bad now that I strengthen my eye muscles with exercises (which I still have to do now and then), but if I'm the least bit tired or distracted, these vision problems can still happen to me all these decades later (I'm in my late 40's now). Like he says so well in the speech with the bicycle analogy, my vision was very broken, and it didn't just affect my ability to read. It affected, and still affects, my ability to judge distance, track movement, focus on objects or on people, see details of things properly, etc. This has effects on practically every aspect of daily life. Like he said, I wasn't any good at sports that involved moving objects - which is most of them. The only one I was kind of good at was running and I had the stamina to run long distance races. Too bad my community didn't care about track and field very much. They were all about rodeo, football and basketball - three things I couldn't do at all. Even social interactions are difficult because people might assume that I'm avoiding them or that I'm lying to them because I can't maintain eye contact with them for more than a few seconds at a time. It takes so much concentration to see properly that I'm actually better off not even looking at a speaker if I need to focus on what he or she is saying. I'll subconsciously turn my head so that my right ear is pointed towards them instead. I'm so glad that people are talking about these issues more now and that there are people like Cameron who are working so diligently to help others with their vision challenges! Great talk!
This is my go to video to help parents understand when I say they should consider a Developmental Optometrist evaluation for their student. It has helped multiple kids get visual problems treated.
Excellent description of the visual process--explains so clearly as to why so many children and adults have difficulty with literacy issues. Thank you, Cam, for your passion and knowledge base on a topic so important to so many people.
Wow! This gave me so much to think about. Seeing all those different types of vision was really helpful. I am longsighted, myself and had to manage without glasses which means that I didn't get the chance to develop all those visual skills as my eyes were permanantly stressed at near. This lecture has so much information. Thank you.
Wow so amazing my 17 year old daughter was recently diagnosed with this and your explanation has helped me so much with my understanding of her issue. Sad truth is medical insurance doesn't cover vision therapy. Such a hardship when you want to help your child .
Is that convergence insuffiency? He covers so much in this lecture. Just so you are aware I was misdiagnosed with this and it turned out eventually to be longsightedness which the opticians just did not want to deal with. Eventually one listened to me and a pair of plus glasses was all I needed which you can pick up cheaply in many shops. For the first time I could concentrate and remember stuff as well as getting rid of the horrendous migraines I had. I hope you are able to find some help with your girl.
Insurance companies have recognized treatment for convergence (eye teaming) problems to be proven effective and will cover. VSP will cover treatment if employer has elected to include coverage in their benefits package. Talk to your company's HR department and let them know it matters to you.
As a chiropractor who treats the cranial nerves with red light therapy successfully I appreciated your Tedtalk. Where can these glasses you use and the reading software be purchased?
Hello Cameron, Thank you for giving to me such a good excample of a clear explanation about visual development and reading problems. I am working in the profession of Bahavioral Optometry for 30 years in the Netherlands and still find it difficult to create some spin off after a lecture. I guess you are more succesfull in that way. I am alreay searching for soem years for a good read analyser and never saw the one u have. So please can you inform me about the factury . Thanks in advance and succes with you inportant work. Best Regards Hans van den Brink
Debra Moore Hi Debra, The best thing that can be done is reach out to a local developmental/behavioural optometrist in your area. COVD.org and OEPF are great resources. Hopefully this will allow you to find someone who will be able to help. Please feel free to reach out to me directly with any questions. www.drmccrodan.com has our contact information.

A short and well-organized TEDx talk on what vision is, what happens when it goes wrong, and why it is important.
Thank you Dr. McCrodan, explaining vision in 11 minutes!
This is my go to video to help parents understand when I say they should consider a Developmental Optometrist evaluation for their student. It has helped multiple kids get visual problems treated.
Wow!! I greatly appreciate this talk!
Fantastic video about what vision therapy is and what it can do!
Excellent description of the visual process--explains so clearly as to why so many children and adults have difficulty with literacy issues. Thank you, Cam, for your passion and knowledge base on a topic so important to so many people.
Masterful! Dr. McCrodan covers the topic well, with a message for all learners.
Wow! This gave me so much to think about. Seeing all those different types of vision was really helpful. I am longsighted, myself and had to manage without glasses which means that I didn't get the chance to develop all those visual skills as my eyes were permanantly stressed at near.

Thanks for helping me go from 20/50, to 20/20 in one year.
No more myopia for anyone, as objective science.
Nice job, Dr. McCrodan!

medical doesn't cover it you would have to have a separate vision insurance plan
you're right absolutely
