Saccade is a term used to describe the rapid, involuntary movements of the eyes. Although saccade is the most commonly used term to describe these movements, there are several other synonyms that can be used interchangeably. Some common synonyms for saccade include eye flick, eye jump, rapid eye movement, and eye dart. These synonyms are typically used in the same context as saccade when referring to quick, jerky movements of the eyes. However, saccade remains the most precise and widely accepted term for these types of eye movements in clinical and scientific circles.
