Eye movements refer to the voluntary and involuntary movements of the eyes that allow us to focus on different objects and track motion. These movements are essential for activities such as reading, where the eyes move from word to word, and for scanning the environment to gather visual information. There are several types of eye movements, including saccades, which are quick jumps between points of interest, and smooth pursuit, which allows the eyes to follow moving objects. Additionally, fixations occur when the eyes remain still to gather visual information, playing a crucial role in how we perceive our surroundings.
