Particularly when associated with dry eyes, blepharospasm may be relieved with warm compresses, eye drops, and eye wipes. [40] [41] A Japanese study showed that warm compresses containing menthol were more effective in increasing tear film. [42] Drugs used to treat blepharospasm are anticholinergics, benzodiazepines, baclofen, and tetrabenazine ...
Blinking is a bodily function; it is a semi-autonomic rapid closing of the eyelid.
