What Happens If You Sleep With Contacts On

What a contact lens does is limit the oxygen.

If you sleep with contact lenses you may end up having a red eye along with pain in the eye and extreme light sensitivity. Of course corneal neovascularization doesn t happen overnight. This process is called keratitis which means that the physiology of the eye is being damaged and altered. But most people who get it also have experienced some kind of eye trauma involving a plant branch or stick.

However when you are sleeping your eyelids are shut and there is less oxygen being transmitted to your cornea from the surrounding air if you have left your contact lenses in this prevents even more oxygen from getting to your eye because the plastic acts as a physical barrier to the process. Sleeping in your contacts increases your risk of getting fungal keratitis. The cdc suggests that sleeping in your contacts increases your risk of developing a nasty sounding infection called microbial keratitis by six to eight times. Sleeping with contacts can increase eye infections without proper access to oxygen your corneas will start to get larger and swell up.

That s because sleeping in your contacts can make you more susceptible to microscopic tears on your cornea and increases your odds of bacteria as well as less common fungi entering your eye. You can risk damage to your cornea even after sleeping with your contacts in once. When you sleep your eyes miss out on ambient oxygen exposure a key component of keeping eyes healthy. So what happens when you sleep with contacts.
