Active Focus attempts to push the distant vision of the eyes slightly further. However, as [[accommodation]] is ~~an involuntary~~ process, achieving Active Focus is not straight forward. While it is easy to move the skeletal muscles of your body, it is not possible to control the [[ciliary muscle]]s in the same way. However, by careful manipulation of the [[blur horizon]], it is possible to encourage the eyes to push slightly harder to achieve focus. This extra push is what Active Focus is about.

In order to do this successfully, it is important to introduce appropriate amount of [[blur]] challenge to the eyes. This can be accomplished by the use of [[normalized]] and [[differential]] glasses. As opposed to full correction glasses where everything is always sharp, normalized and differential glasses provide convenient access to a blur horizon. This blur horizon allows for the practice of Active Focus. Again, the blur challenge should not be so much that it is too difficult for the eyes and not so little that it is unnoticeable.
