What causes twitching of the eyes and is it normal?

Well, under usual circumstances, the annoying eye twitch would normally be caused by the not so serious factors as follows.

  • Stress
  • Tiredness
  • Eyestrain
  • Caffeine
  • Alcohol
  • Dry eyes
  • Nutritional imbalances
  • Allergies

Next, under such situations, such annoying symptoms would usually come and go within a very short period of time and certainly the conditions would get better and better from time to time especially when certain related treatments are sought and administered to deal with the symptom.

However, under rare circumstances when the eye twitch symptom just get progressively and chronically and seriously unmitigated from bad to worse as well as seem to last permanently even when all sorts of related treatments are administered upon such illness to deal with it, such non-stop eye twitching symptom may then simply just manifest as one of the serious neuromuscular / neurological symptoms of :

Tardive Dyskinesia (rapid involuntary uncontrollable eye blinking / eye twitching), which in most cases are caused by the neuromuscular / neurological side effects of certain medications and other neurological complications. Whilst the underlying mechanism of such a disease is such that the normal functionings of the neurotransmitters chemical dopamine which co-ordinates the miscellaneous human body movements in this case are disturbed,antagonized and disrupted in this case resulting in one's loss of control of human body movements, and in this case, one's eye / eyelids organ.
