The Hidden Danger of Sleep Masks

A man with a sleep mask on top of his head, holding his hands to his eyes to show how the hidden danger of sleep masks affects vision.

Do you use a sleep mask for sleeping?


If so, this is going to be one of the most important articles you’ll read.


Sleeping masks are cost-effective, easy to use, and have been scientifically proven to improve sleep.(1) 


However, there is a hidden danger that most people don’t know about.


In fact, it’s so damaging to your eyes you may NEVER want to use a sleep mask again.


This article will explain sleep mask side effects through Tim’s nightmarish experience with his sleeping eye mask. So, keep reading.

Modern-Day Sleep Woes

As an ambitious businessman, Tim lives a busy life.


He flies frequently, works long hours, and is 100% focused on growing his venture.


On top of all that, there’s also the personal life to maintain.


Needless to say, Tim felt like he had been burning the candle at both ends. Tim knew if he could just improve the quality of his sleep, he’d be able to work more efficiently, increase business growth, and still have enough energy left for all the best things in life.


Thus began Tim’s tango with the sleep mask.

Blurry Vision Due to Pressure

A girl with blurred vision staring at her hand.

Sleep eye masks have been scientifically proven to improve sleep(1), and are recommended by experts.


So, under both the advice of his physician and friends, Tim purchased a sleep mask from Amazon.com.


Initially, Tim was in love with it. Whether at home or on a plane, the light blocking significantly improved his sleep quality, leaving him feeling energized upon waking.


However, soon Tim became irritated by the pressure the mask put on his eyes.


*If you can’t imagine it, close your eyes and press down on your eyelids for 10 seconds to see how blurry your vision gets.*


If that’s what 10 seconds of pressure can do, imagine what 7 to 8 hours each night could do to your eyes.


Tim became very worried when he noticed how long it took to focus his vision in the morning, after using his sleep mask for the night.


Sometimes he would experience blurry vision for 20 to 30 minutes after waking. And he noticed it was getting worse over time.


Needless to say, Tim was frightened by this experience.


So, can sleeping masks cause blurred vision? Unfortunately, this is the reality with most sleep masks strapped to your face. A lot of people can strap common sleep masks on too tightly, and there is direct pressure on your eyeballs.


It can cause undue pressure on your corneas and you may notice some blurriness upon waking up. Although this usually passes within the first few hours, it's still a cause for concern if you continually apply this kind of pressure on your eyes.

Is it bad to wear a sleep mask at night?

We investigated Tim’s claims (and the claims of many others) and discovered that there is cause for concern when it comes to constant pressure on your eyes. Research conducted by Professor Charles McMonnies of the UNSW School of Optometry and Vision Science indicates that rubbing or applying pressure to your eyes could accelerate the progression of pressure-sensitive eye diseases(2).


The constant pressure from Tim’s sleep mask could have caused:

An eye with dotted lines to show corneal distortion, a hidden danger of sleep masks.


  • Corneal distortion: the pressure actually changes the shape of his cornea.

  • Limited circulation: compression of the eye tissue limits blood flow to his orbs.

Both of which lead to blurriness, and if continued, can potentially cause more serious medical conditions like glaucoma or keratoconus. Yikes!

In fact, Professor McMonnies strongly recommends avoiding sleep masks that apply pressure to your eyes.


Some people also ask: do sleep masks cause styes? While sleep masks have not been proven to be a direct cause of styes, wearing one can be a contributing factor. Particularly,  if yours presses on your eyelids. The material can cause some skin irritation and, if not washed regularly, can lead to dirt building up in that area.


Another frequently asked question is: can a sleep mask suffocate you? The quick answer is no. Even common sleep masks that apply pressure on the eyes do not usually affect your breathing, as sleep masks are designed to only cover your eyes. The nose and mouth are left free and clear so as not to impede breathing and airflow. In short, you just need to know how to wear a sleep mask properly, and you won't have any problems.

Why Most Sleep Masks Are a Bad Idea

Tim was in a love-hate relationship with his sleep mask.

The eye mask did help him to sleep better in hotel rooms with flimsy curtains, on frequent flights across time zones, and even in the office when it’s time for a power nap.


However, the constant pressure on his eyes and the blurry vision it was causing are serious medical concerns.


Beyond that, Tim was also unsatisfied in other areas:


  • His sleep mask does not provide full blackout. There was always some light leaking through the gap at his nose.

  • He could never achieve the perfect fit. The mask always slipped off his face during the night, but if he tightened the strap, there would be even more pressure on his eyes.

  • The Velcro closure would cling to and pull on Tim’s beautifully wavy hair. Ouch.

  • The synthetic material was hot, uncomfortable, and led to “sweaty eyes.”

Why Is It Good to Sleep With An Eye Mask?

Tim knew there had to be something better.


The fact that sleep masks can significantly improve your sleep quality is scientifically proven and undisputed.


However, most eye masks are unscientifically designed and put a dangerous amount of pressure on your eyes.


But what if you could find a truly premium, effective, and science-based sleeping mask that solves these problems?


You’d be looking forward to a bunch of benefits including:


  • Deeper, uninterrupted sleep

  • Relief from insomnia

  • Balance between REM and NREM sleep

  • Sleep anywhere in peace

  • Fall asleep faster


Best of all, with absolutely ZERO pressure on your eyes?


That’s when Tim found Manta Sleep Mask.
