The upper eyelid of my left eye has has been twitching for a few days. I googled to find out why this started suddenly, and whether I need to worry about it. Here’s what I found:
Called myokymia in doctor lingo, these rippling muscle contractions in an eyelid can be triggered by:
- Stress
- Tiredness
- Eye strain
- Caffeine
- Alcohol
- Dry eyes
- Nutritional imbalances
- Allergies
OK, one question answered, and now I have a new one: Given the potential causes, why have my eyelids not twitched every day of my adult life?
