What is the reason behind occasional and discontineous tense blinking? I noticed that it's frequency increases when stressed or worried. On the other hand it sometimes occurs for no obvious reason.

its exact cause is unknown but it is like any muscle twitch it can be caused by a nerve tapped causing short period twitching
there might be several causes for that the most are simple ,it is a benign condition ,but when this presentation is more frequent and has more time duration and accompanied by other symptoms it would indicate other serious conditions ,it may be the earliest sign of a chronic movement disorder, especially if other facial spasms develop in addition to the eye twitching,otherwise it is harmless and can be caused by :
Alcohol intake,Bright lights,Caffeine intake,Fatigue,Irritation of the eye surface or inner eyelids,Lack of sleep,Smoking,Stress,Wind
so it is right it can be caused by stress .
