An eyelid twitch or tic is an involuntary spasm of the eyelid muscles. I’ve noticed twitches tend to occur in the same location. The most common causes are fatigue, stress, caffeine and eyestrain. So the best treatments include prevention of the causes: relax, get more sleep and consume less caffeine.
There are more serious twitches that involve the face and cause the eye to close with each spasm. Neurological causes must be ruled out. Temporary treatment is an injection with botulinum toxin (Botox). This relieves the spasm and allows the muscles to relax.
Most eyelid twitches are more annoying than serious.
