We've all been there. You're going about your business of the day, and that one stupid eye just won't stop twitching. All that involuntary almost-blinking can really get distracting, right?

Ever wondered why exactly the eye twitches? Allow us to break it down for you.

The annoying little tic, as reported by Cosmopolitan, known as eyelid myokymia, it's only temporary and normally lasts from a few minutes to a day.

Why does the twitch even start, though?

Multiple theories have been thrown around in this regard. They say anything between stress and caffeine or even staring at your computer screen for too long can cause 'em. But Dr. Blackeney says these are relatively unlikely reasons.

"More than anything, it can be down to tiredness and lack of sleep. So ensure you get plenty of rest if you get twitches in your eyes a lot."

Contrary to how a lot of us feel when a massive eye-twitch won't get off our back, other people can't see them. Even though it's all we can think about, most twitches are too subtle for people to notice.

But can you do anything about this utter nuisance? Of course.

1. Don't smoke: Studies reveal that smokers are at a greater risk for macular degeneration, a condition that causes blindness.

2. Eat a balanced diet: Eating fresh fruit and veggies can help you maintain optimum eye health.

3. Maintain a healthy weight: Being overweight may have effects of your sight too. Obese people too, are more susceptible to macular degeneration.

4. Protect your eyes: It's important to wear sunglasses that protect you from harmful rays of the sun. Even when it's overcast, UV rays can pose a threat.

5. Get regular eye check-ups: Timely visits to the optometrist will help you catch and treat age-related eye conditions in time.

There you have it. If you keep these little precautions in mind, a little eye-twitch probably means nothing.
