“While we’re all under stress at times, our bodies react in different ways. Eye twitching can be one sign of stress, especially when it is related to vision problems such as eye strain (see below). Reducing the cause of the stress can help make the twitching stop.
Vision-related stress can occur if, for instance, you need glasses or a change of glasses. Your eyes may be working too hard, triggering eyelid twitching.
Computer eye strain from overuse of computers, tablets and smartphones is also a very common cause of vision-related stress.”
