Eye Health Guide advises seeing a clinician only if it lasts more than a few weeks, closes the eye completely, spreads to the rest of the face, or comes with other symptoms. ## Get it checked if - The twitch lasts more than a few weeks without settling - Spasms close the eye completely or force repeated strong blinking - Twitching spreads to the cheek, mouth or other parts of the face - It comes with a drooping eyelid, redness, discharge or other new symptoms ### On this page ⌄ 1.

Frequently asked questions ## Why eyelids twitch An eyelid twitch is a brief, involuntary fluttering of the eyelid muscle, usually in one eye. It is very common and almost always harmless. Typical triggers include tiredness, stress, too much caffeine or alcohol, eye strain from screens, and dry eyes. ## How to settle a twitch Most twitches fade once their triggers ease. - Get more sleep and rest your eyes - Cut back on caffeine and alcohol - Take regular screen breaks and manage stress - Use lubricating drops if your eyes feel dry ## When it might be blepharospasm Repeated, forceful blinking or eyelid closure — usually in both eyes — that interferes with reading, driving or daily life is different from a minor twitch. This condition, blepharospasm, is usually long-term but is well controlled in most people with specialist treatment, typically injections that relax the eyelid muscles. ## Read next ## Frequently asked questions ### Why does my eye keep twitching? Most eyelid twitches are linked to tiredness, stress, caffeine, eye strain or dry eyes, and settle on their own once those triggers ease. ### How long is too long for an eye twitch? Most settle within days. If a twitch persists beyond a few weeks, book a routine check with an optometrist or clinician. ### Can an eye twitch be a sign of something serious? Rarely. On its own it is almost never serious. Spreading facial spasm, complete eye closure, or other new symptoms are the patterns that need assessment.
