Eye twitching, or myokymia, is an involuntary eyelid muscle contraction that usually affects the lower eyelid.
The exact cause is unknown but it sometimes develops during times of increased stress and has also been associated with high caffeine intake, fatigue or excessive squinting. It can also occur after reading or working on a computer for prolonged periods of time.
An eyelid twitch is usually a sign that you need to take a break and relax. Sometimes a twitch will go away following a good night's sleep, but a stubborn twitch may last as long as three weeks.
If the twitching involves both eyes, there is a possibility that you have blephorospasm. This is a chronic condition that is more common in women over 50. Blephorospasm can progress into repeated forceful closing of the eyes. Again, there is no definite cause, but it may be worsened by stress, bright lights, watching too much TV, and fatigue.
To relieve an eye twitch, try applying warm compresses to the twitching eye and gently massaging the eyelid with your fingers. For eyelid twitches that last longer than 2 or 3 days, over-the-counter oral or topical (eye drop) antihistamines may offer some relief. Although not a direct treatment, antihistamines slow down the muscle contractions, or twitching, making it less annoying.
Interesting is that somwhere did say you could get botox to help with it!
Seems it is not a concern unless it doesn't go away.
Fatigue is a big cause so I guess we may be stuck with it!
