why is my right eye twitching

The twitching of the right eye is most commonly caused by fatigue, stress, or muscle spasms around the eye. Other frequent triggers include eye strain from prolonged screen use, high caffeine or alcohol intake, and sometimes conditions like dry eyes or eyelid inflammation. Usually, eye twitching is temporary and harmless, resolving once the body rests and stress is reduced. However, if the twitching persists beyond 2-3 weeks, causes the eyelid to close completely, spreads to other parts of the face, or is accompanied by redness or swelling, it is advisable to seek medical attention as these could indicate more serious neurological or eye conditions.
