Visual Input and Signs of Eyesight, Focusing or Eye Teaming Problems

Vision is a process of the eyes gathering information from the outside world, the visual pathways sending the information to the brain, and the brain then deciphering the information and making decisions about what has been seen.

Learning is 80% visual. So, it’s important that the visual system is working its best to contribute to the learning process. This means every step of the process needs to be working well.

The first stage is visual input. This is the work of the eyes. The eyes need to send a clear, effortless and image to the brain.

Clear: this requires good eyesight. It is important to correct any myopia, hyperopia or astigmatism first.

Effortless: this requires a strong, flexible focusing system. It is important to correct any accommodation dysfunctions first.

Single: this requires the two eyes to work well together as a team (binocular vision). It is important to correct any oculomotor dysfunction, fixation disparity, amblyopia and/or strabismus first.

Glasses or vision therapy are often used to correct any eyesight, focussing or eye teaming problems.
