Children with tracking problems will often lose their place when reading, skip or transpose words, and have difficulty comprehending because of their difficulty moving their eyes accurately. ? Because children with tracking problems cant control their eye movements at close ranges, this is how their eyes move when they read, especially as they fatigue: ;Focusing, or accommodation--the ability to see clearly.? At the close ranges required for reading, this is the visual skill needed to maintain clear sharp images for extended periods of time. It also includes the ability to quickly shift focus when looking from near to far, such as when looking from desk to board.? For children with accommodation problems, print will become progressively blurry as they read for longer periods of time, and their eyes will fatigue from the strain of trying to keep the print clear.
