Eye twitching is a very common complaint which can affect pretty much anyone at any time. The problem usually consists of the bottom lid of one eye seeming to act independently of the rest of the eye. However, it is not always the bottom lid and in some people the upper eyelid has been known to twitch instead.
Although these symptoms can be annoying and distracting, eye twitching often comes and goes and you may experience it at several points in your life. Twitching can last a few days or longer, sometimes weeks and even months. It can feel as though the spasm is so powerful that those around must be able to notice it. However, if you look in the mirror, you will realise that the movement is so subtle it is unlikely that anyone will take note.
Speak to your doctor or optician if you have experienced these symptoms for a prolonged period of time, as they will notice if there is an underlying issue with your eyes or vision.
