Eye movement refers to the motion of the eyes as they shift focus from one point to another. This movement is essential for visual perception, allowing us to track moving objects, scan our environment, and read text. The eyes can move in various ways, including saccades (quick jumps), smooth pursuits (following a moving object), and fixations (holding gaze on a specific point). Different muscles control eye movement, including the extraocular muscles, which are attached to the outer surface of the eyeball. These muscles work together to enable coordinated movements, ensuring that both eyes align properly for depth perception and a clear view of the world. Proper eye movement is crucial for activities like reading and driving.
