When your right eye keeps twitching, it generally means that the muscles around your eyelid are experiencing involuntary spasms. This is a common and usually harmless condition called eyelid myokymia, which can be triggered by several factors such as stress, fatigue, eye strain, caffeine intake, dry or irritated eyes, and lack of sleep

. Common causes include:

• Stress and anxiety
• Fatigue or insufficient sleep
• Eye strain from prolonged screen time or focusing on tasks
• Excessive caffeine or alcohol consumption
• Dry eyes or eye irritation from allergies or environmental factors
• Side effects of certain medications
• Dehydration

In most cases, eye twitching is temporary and resolves on its own without treatment

. However, if the twitching is persistent, severe, affects other parts of your face, or is accompanied by other symptoms like eyelid drooping or eye redness, it may indicate a more serious neurological condition such as benign essential blepharospasm, hemifacial spasm, or other nervous system disorders, and you should seek medical advice

. Cultural perspectives:
Some cultures interpret right eye twitching as a sign of good luck or impending events, but these beliefs lack scientific evidence and should not replace medical evaluation if symptoms persist

Summary

Right eye twitching usually means mild, involuntary eyelid muscle spasms caused by lifestyle factors like stress, fatigue, or caffeine. It is typically harmless and temporary. Persistent or severe twitching warrants medical attention to rule out underlying neurological issues
