Do you know what, wearing contact lenses can make your eyes look truly mesmerizing?
For some, wearing contact lenses is fashionable, while for others its more of a necessity.
People with weak eyesight usually prefer wearing glasses, lenses, or get laser treatments. And among such people, some do not prefer to wear spectacles just because they are afraid, they will look nerdy. Whether you want to wear contact lenses occasionally at a party or you like to wear them regularly at work, taking those lenses off and wearing them can be quite a hassle. Be it weekly disposable contact lenses, monthly or two-week disposable lenses. In any case, falling asleep with your lenses on should be out of the question, as it could get quite damaging to your eyes.
What happens when you sleep in contact lenses?
As per the U.S. - Centers for Disease Control and Prevention (CDC), sleeping in contact lenses increases the chances of contracting severe eye infection six to eight times! You probably ask why and here the answer to that is. When you 're up, your eyes are usually open (maybe even during the excessively long weekly meeting at work). As contacts lock your eyes shut, oxygen would not enter the corneas. Which may induce oxidative stress, resulting in swelling, dry eyes, swollen eyes, abrasions (scratches on the eye surface), allergies, corneal ulcers, and irreversible sight loss.

Contact lenses can gather dirt and debris and have infections if they are not washed, cleaned, and disinfected regularly whether they are monthly or two weekly contact lenses, or if they are regular lenses disposed of after a single usage. This may cause temporary/permanent loss of vision and corneal abrasions (scratches on the eye surface).
Conjunctivitis (more commonly referred to as the pink eye) is a common infection that causes a red and aggravated appearance. Conjunctivitis is usually not painful and can be treated easily with prescribed drops or over the counter eye drops. This typically clears up after a few days and can be triggered by the improper wearing of contacts.

An illness that he received during the hunting trip from sleeping with his contact lenses! His left cornea produced a massive ulcer and it ruptured, cutting a hole in his eye.
