Is It Bad for My Eyes to Sleep with Contacts In?

If you're someone who wears contact lenses, you've probably wondered at some point whether it’s okay to fall asleep with them in. The short answer is: no, it’s not a good idea if your contact lenses are not approved for overnight wear. Sleeping in contact lenses designed solely for daytime use can have serious consequences for your eye health. Let’s explore why this practice can be harmful, the importance of good eye hygiene, and how regular eye exams with an optometrist, like those at iCare Family Vision, can keep your eyes healthy and your vision sharp.

Why Sleeping in Contacts Can Be Harmful

Contact lenses sit directly on the surface of your eye, known as the cornea. The cornea requires oxygen to stay healthy, and while contact lenses are designed to allow some oxygen through, they still reduce oxygen flow compared to having no lens on the eye. When you close your eyes to sleep, you limit oxygen even further. Combine this with a contact lens that’s not made for overnight wear, and you’re creating a perfect storm for potential problems.

Here are some of the key risks:

  1. Increased Risk of Infection Sleeping in contact lenses significantly raises your risk of developing an eye infection. Without adequate oxygen, the cornea becomes more susceptible to bacteria and other microorganisms. This can lead to conditions such as microbial keratitis, an infection that can cause pain, redness, and in severe cases, permanent vision loss. Studies show that people who sleep in their contacts are up to eight times more likely to develop an eye infection compared to those who remove their lenses at night.

  2. Corneal Inflammation (Hypoxia) When the cornea doesn’t get enough oxygen, it can become swollen and irritated—a condition called corneal hypoxia. Chronic hypoxia can lead to long-term complications, including reduced corneal sensitivity and scarring. Over time, this can compromise your overall eye health and make wearing contact lenses uncomfortable or even impossible.

  3. Dryness and Discomfort Contact lenses can dry out your eyes, especially while sleeping. Tears, which help keep your eyes hydrated and free from debris, don’t circulate as effectively when your eyes are closed for extended periods. Waking up with dry, irritated eyes is a common complaint among those who sleep in their lenses. This dryness can make it difficult to remove the lenses in the morning, potentially causing further irritation or scratches to the cornea.

  4. Formation of Corneal Ulcers A corneal ulcer is an open sore on the cornea, often caused by bacterial infection. Sleeping in contacts can increase the likelihood of developing these ulcers, which require immediate medical attention and can cause permanent damage if left untreated. Corneal ulcers are not only painful but can also lead to vision loss if they result in scarring or other complications.

The Importance of Good Eye Hygiene

Practicing good eye hygiene is essential to avoid complications from contact lens use. Here are some key habits to follow:

  • Remove Your Contacts Every Night: Always take out your contact lenses before going to bed, unless they are specifically approved for extended wear by your optometrist. This simple step can significantly reduce your risk of infection and other complications.

  • Clean Your Lenses Properly: Use the recommended cleaning solution to disinfect your lenses every day. Never use water or saliva, as they can introduce harmful microorganisms. Additionally, make sure to clean your lens case regularly and replace it every three months to prevent bacterial growth.

  • Replace Lenses as Directed: Follow the replacement schedule for your specific type of contact lens. Wearing lenses past their intended lifespan can lead to a buildup of deposits and increase the risk of infection. Whether your lenses are daily, bi-weekly, or monthly, adhering to the recommended schedule is crucial for maintaining eye health.

  • Wash Your Hands: Before handling your contact lenses, wash your hands thoroughly with soap and water to avoid transferring bacteria to your eyes. Dry your hands with a lint-free towel to prevent any particles from getting on your lenses.

  • Give Your Eyes a Break: If possible, wear glasses occasionally to allow your eyes to rest and breathe more freely. This is especially important if you’ve been wearing contacts for extended periods during the day.

Why Regular Eye Exams Are Essential

Even if your eyes feel fine, regular visits to your optometrist are crucial for maintaining optimal eye health. Many contact lens-related complications can develop slowly and without noticeable symptoms until they become serious. By attending routine eye exams, your optometrist can detect early signs of potential issues, ensure your contact lenses are the right fit, and recommend any adjustments to your prescription or lens type.

During an eye exam, your optometrist will also assess the health of your cornea and check for any signs of dryness, inflammation, or infection. They can provide valuable advice on proper lens care and hygiene tailored to your specific needs. If you’re considering switching to lenses approved for overnight wear, your optometrist will evaluate whether your eyes are suitable for this type of lens and monitor your progress to ensure your eyes remain healthy.

Tips for Breaking the Habit of Sleeping in Contacts

Breaking the habit of sleeping in your contact lenses may require a bit of effort, but it’s worth it for the long-term health of your eyes. Here are some practical tips to help you:

  • Set a Reminder: Place a sticky note on your bathroom mirror or set an alarm on your phone to remind you to remove your lenses before bed.

  • Create a Nighttime Routine: Incorporate contact lens removal into your nightly routine, just like brushing your teeth. Over time, it will become second nature.

  • Keep a Spare Pair of Glasses Handy: If you feel too tired to remove your lenses at night, having a pair of glasses nearby can serve as a reminder to take them out and switch to a more eye-friendly option.

  • Educate Yourself: Understanding the risks of sleeping in contact lenses can be a powerful motivator. Remind yourself that taking a few extra minutes at night can prevent serious eye health issues.
