KK: /ˈblɛf.ə.roʊˌspæz.əm/
A condition where the eyelid muscles contract involuntarily, causing repeated blinking or spasms.
The doctor explained that blepharospasm can be quite uncomfortable and may require treatment.
Blepharospasm is formed from "blepharon" (from Greek "βλέφαρον", meaning eyelid) and "spasmos" (from Greek "σπασμός", meaning a sudden involuntary contraction). The word describes a sudden involuntary contraction of the eyelid muscles.
Think of 'eyelid' ('blepharon') and 'sudden contraction' ('spasmos') to remember that 'blepharospasm' refers to an involuntary spasm of the eyelid.
