Eye tracking is the coordinated precise eye movements crucial for reading efficiency and sports performance. Fixations are tracking skills of sustained and steady gaze required for visual attention and recall. Saccades are precise eye movements from one target to another that are important for reading efficiency and pursuits are the coordinated eye movements essential for following moving targets and accurate eye-hand coordination. Deficient eye tracking skills can result in loss of place or skipping lines while reading, re-reading lines, or poor eye-hand coordination. Vision therapy can help re-train the eyes to improve those skills needed to track words and objects accurately.
