Detailed explanation-1: -Voluntary or guided saccades are eye movements initiated to bring an object-of-interest into view or initiated under direction (e.g., to the command “eyes left”). Saccades consist of short, rapid, jerky (ballistic) movements of predetermined trajectory that direct the eyes toward some visual target.

Detailed explanation-2: -The eyes move smoothly instead of in jumps. They are called pursuit because this type of eye movement is made when the eyes follow an object. Therefore, to make a pursuit movement, look at your forefinger, at arms length and then move your arm left and right while fixating your finger tip.

Detailed explanation-3: -The cerebellum plays a pivotal role in the control of eye movements. Its core function is to optimize ocular motor performance so that images of objects of interest are promptly brought to the fovea – where visual acuity is best – and kept quietly there, so the brain has time to analyze and interpret the visual scene.
