What causes persistent twitching in the right eye?

Right eye twitching, known as eyelid spasm, is usually caused by factors such as muscle fatigue, excessive stress, lack of sleep, or electrolyte imbalance. This phenomenon is typically temporary and not associated with any serious health issues. If the twitching persists for a long time or occurs frequently, it may be related to eye diseases, neurological conditions such as Bell's palsy, or certain systemic diseases like anemia or thyroid dysfunction. Note that if the eye twitching continues, affects daily life, or is accompanied by other symptoms such as facial weakness or vision loss, prompt medical attention is advised for a comprehensive evaluation by a physician to rule out potential underlying health problems.
