Dangers Of Sleeping In Contacts: Infections & More
Can you really catch some Z's with your contact lenses in? The overwhelming consensus from eye care professionals is a resounding no. While the allure of skipping that nightly lens removal ritual might be strong, the potential consequences for your eye health are significant enough to warrant a closer look.
Contact lenses, while a marvel of modern vision correction, introduce a foreign object to the delicate surface of your eye. This inherently alters the natural environment, impacting oxygen flow and tear film distribution. When we sleep, our eyelids are closed, further limiting the already compromised oxygen supply to the cornea. This creates a perfect breeding ground for bacteria, increasing the risk of infections like keratitis, a potentially sight-threatening condition.
| Topic | Risks of Sleeping in Contact Lenses |
|---|---|
| Key Information | Sleeping in any type of contact lens significantly increases the risk of serious eye infections, corneal damage, and discomfort. Even occasional naps with lenses in can be harmful. Silicone hydrogel lenses, while marketed for extended wear, still carry risks and should be used under strict guidance from an eye care professional. |
| Related Conditions | Keratitis (inflammation of the cornea), Corneal Ulcers, Microbial Keratitis, Acanthamoeba Keratitis, Giant Papillary Conjunctivitis. |
| Preventive Measures | Establish a routine for removing contact lenses before bed. Use alarms or reminders. Consult an eye doctor for advice on appropriate lens wear and care. Practice meticulous lens hygiene, including handwashing and proper cleaning solutions. |

The cornea, the clear front part of your eye, relies on oxygen from the air. Contact lenses, even the most breathable ones, act as a barrier, reducing this vital oxygen flow. During sleep, this reduction becomes even more pronounced, potentially leading to corneal swelling, inflammation, and in severe cases, ulcers. While symptoms may initially manifest as mild redness, blurry vision, or a gritty sensation, ignoring these warning signs can have dire consequences, including permanent vision loss.
Perhaps you've heard anecdotes of individuals who claim to have slept in their contacts for years without issue. This doesn't negate the scientific evidence highlighting the heightened risks. Just because an infection hasn't occurred yet doesn't mean it won't. It's akin to playing Russian roulette with your eyesight. The odds may seem favorable in the short term, but the potential outcome is simply not worth the gamble.
Even a short nap with contact lenses can disrupt the delicate balance of your ocular environment. The pressure from the lens against your closed eyelid can cause microscopic abrasions on the corneal surface, providing an entry point for bacteria. That quick power nap could result in a painful infection, requiring medical intervention and potentially leading to long-term complications.
The CDC reports that a staggering one in three contact lens wearers admit to sleeping or napping in their lenses. This common practice contributes significantly to the high incidence of preventable eye infections. Dr. Reynolds, an ophthalmologist, emphasizes the importance of lens removal, stating, "Anytime you sleep in a contact lens, the risk goes up." Bacteria thrive in the warm, moist environment created when lenses are left in overnight. This makes the cornea more susceptible to infection, particularly if its already dry or scratched.
While some specialized extended-wear contact lenses are designed for overnight use, these still carry risks and require careful monitoring by an eye care professional. Even with these lenses, regular cleaning and proper hygiene are paramount to minimize the risk of complications. Never assume that any contact lens is entirely safe for sleeping. Always consult your eye doctor for personalized advice based on your individual eye health and needs.
So, what should you do if you accidentally fall asleep with your contacts in? Remove them immediately upon waking. If your eyes feel irritated, clean your lenses thoroughly before reinserting them. If the irritation persists, consult your eye doctor. Don't hesitate to seek professional advice if you experience any unusual redness, pain, or changes in vision.
Forming a consistent routine for contact lens removal is crucial. Make it a habit to remove your lenses at the same time each night, just like brushing your teeth. Set reminders on your phone or use visual cues to prompt you. Investing a few extra minutes each day to properly care for your contact lenses can protect your vision and prevent potentially serious complications. Remember, healthy vision is a precious gift, and taking simple precautions like removing your contact lenses before sleeping is a small price to pay for its preservation.
Beyond the risk of infection, sleeping in contacts can lead to other uncomfortable symptoms like dryness, redness, and a feeling of something foreign in your eye. Napping with contacts can exacerbate these symptoms, turning a brief rest into a source of ocular distress. The pressure on your eyes during sleep can also cause the lenses to shift or become damaged, potentially leading to corneal abrasions or injuries. If youre planning a nap, take the time to remove your lenses and store them safely in a clean case with fresh solution.
While extended wear lenses exist, its important to remember they are not a free pass to disregard proper lens hygiene and regular check-ups with your eye doctor. These lenses still require meticulous care and are not suitable for everyone. Discussing your specific needs with your eye doctor is essential to determine whether extended wear lenses are a safe and appropriate option for you. Never attempt to wear daily disposable lenses overnight, as they are not designed for extended wear and significantly increase your risk of infection.
