Nearly 1 million people in the United States end up at the doctor with keratitis every year, according to the CDC.
And the vast majority of those cases were due to improper use and care of contact lenses — including sleeping in them.
And a study from Australia found that people who occasionally sleep in their contact lenses actually have 6.5 times higher risk of keratitis than people who don’t.
That was for people who sleep in their contacts on average LESS than once a week, btw. Not like an every-other-day thing.
It is recommend that you take your contacts out every night. Yes, even if you have those contacts that you supposedly can wear for extended periods of time.
This is something that is confusing to people because there are some lenses that are so-called approved for extended wear, but again it is not recommend for people to be sleeping in lenses.
