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.
You’ll see why through Tim’s nightmarish experience with his sleeping eye mask.
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
Sleep eye masks have been scientifically proven to improve sleep (1), and everyone was recommending it.
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.
Unfortunately, this is the reality with most sleep masks strapped to your face. There is direct pressure on your eyeballs.
Are Eye Masks Bad for You?
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:
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.
In fact, Professor McMonnies strongly recommends avoiding sleep masks that apply pressure to your eyes.
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 lead to “sweaty eyes.”
