Eye Focusing, also called Accommodation, allows a person to maintain clear focus during near work activities. It also performs rapid and accurate focus changes with instantaneous clarity from one distance to another, such as that from a desk to the chalkboard.

Problems with the ability to maintain or change focus are called Accommodative Dysfunction and are quite prevalent among school-aged children. Accommodative dysfunction may interfere with a child’s school performance, prevent an athlete from performing at his or her highest level of ability, or impair one’s ability to function efficiently at work.

When people who lack appropriate accommodative abilities try to accomplish near vision tasks, they may develop ocular discomfort or become fatigued, further reducing visual performance. Due to the visual discomfort, children may not be able to complete reading or homework assignments and may be easily distracted or inattentive. Such children may not report any visual symptoms because they do not realize that they should be able to read comfortably.

Some signs and symptoms associated with Accommodative dysfunction may include the following:

-Vision that is clear and then gets blurry

-Inconsistent work product

-Diminished performance with time on a task and difficulty sustaining near visual function

-Difficulty shifting focus from near to far, like from the board at school to the desk

-Headaches
