It can be confusing to understand how many different things “eye twitching” can mean but another interpretation is blepharospasm. This involves both eyes and is characterized by rapid blinking spasms similar but not the same as hemifacial spasm which involves a single side of the face and is usual minor but can progressively get worse and involve one whole side of the face.
This is classified as a dystonia which basically means a nervous disorder of some kind. There are many different dystonia disorders though so remember to seek help for blepharospasm and you’ll get more specialized information.
Treatment is similar to hemifacial spasm and can be as noninvasive as botox injections and pharmaceutical drugs but may involve surgery or even be untreatable if they’re too severe. Good news though, it’s not painful and is more of an annoyance than anything else.
