Although we think eyeglasses solve all vision problems, in fact, they do not. The ability to clearly read an eye chart at a distance is just a small part of a good vision. That is called Visual Acuity.
Vision is a combined effort of
- How our eyes see and take in information
- How we move our eyes across a page and how they work as a team.
- How our brain makes sense of that information.
We really see in our brain and not in our eyes.
Those 3 must work together to make sure we can use our vision effectively. If the eyes don't function well as a team, or if someone has a poor visual memory, then reading and concentrating is difficult.
Eye allergies, glaucoma, serious eye disease, a piece of metal in the eye - eyeglasses wouldn't remedy those.
Often, problems we assume are learning disabilities or behavioral problems, are actually caused by problems in visual processing.
If someone speaks a foreign language, i can hear them, but i may not be able to make sense of what they are saying.
The point is that someone may be able to see and identify a letter, but not be able to make sense of a word or phrase. They may have a problem in bringing visual information in, or they may have a problem in making sense of what they are seeing.
ADD / ADHD for example, often has a visual component. Children affected by visual processing disorders may have difficulty recognizing shapes and letters, have double vision, read slowly or find math difficult. Schoolwork will be harder if the connection between eye and brain isn’t developed.
Vision Therapy corrects the vision problems that affect learning. School and learning is then easier and more fun for your child.
