Eye Twitching (Myokymia): Definition, Causes and Prevention

Eye twitching, medically known as myokymia, is a common condition characterised by involuntary, repetitive muscle contractions in your eyelid. These twitches can occur either in your upper or lower eyelid and are normally a subtle sensation, to that of a pulse or flutter. It is it not normally associated with any pain and is harmless, however, eye twitching can occasionally be an annoyance or concern, especially in cases of persistence and alongside other symptoms.

However, it’s been led to believe that environmental factors and your lifestyle can play a significant role in is manifestation, with such factors being in high stress environments or prolonged exposure to digital screens.

How to prevent eye twitching?

To prevent eye twitching, this commonly entails addressing your lifestyle and maintaining a high level of overall eye care. Here are some practical steps to help minimise the potential chance of eye twitching:

Get enough sleep:
Fatigue is one of the most common triggers for eye twitching. Aim for 7-9 hours of restful sleep each night to give your body and eyes the recovery time they need.

Manage stress:
Stress can significantly contribute to twitching. Incorporate relaxation techniques into your routine, such as meditation, yoga, or regular physical activity, to help keep stress levels in check.

Take breaks to avoid eye strain:
Prolonged screen time or reading can strain your eyes. Follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds to give your eyes a break.

Moderate caffeine and alcohol intake:
Overconsumption of caffeine or alcohol can overstimulate the nervous system and contribute to dehydration, both of which can trigger twitching. Reducing your intake can help minimize symptoms.
