Eyelid twitch is one of the most common types of eyelid spasms. Eyelid twitch is caused by something we still don't know for sure. Slight spasm of the lower, or even both eyelids is common, and of no concern. Symptoms are twitching or spasm around the eyes, or facial spasms. These symptoms may not necessary mean that you have eyelid spasms. The best would be if you consult your doctor to confirm any diagnosis, whether is good or bad. Treatment for your lower eyelid twitching requires no treatment, as they usually resolve spontaneously. You should reduce stress if there is any, because sometimes it can be provoked by it. Try use warm soaks, or correction of any refractive error also may help. Some ophthalmologists recommend reducing caffeine usage.
