    In brief, you can only sleep in contact lenses that are designed for overnight wear, such as Acuvue Oasys (up to 6 consecutive nights). Other contacts rated for overnight usage include AIR OPTIX NIGHT & DAY AQUA. Outside of Acuvue and Air Optix, PureVision contacts made by Bausch & Lomb is another brand rated for night and day wear. Each of these lenses have been approved by the FDA to sleep in. Seeking guidance from your ECP prior to your using contacts in this mode is also a must as individual situations vary. All of these brands are available on Lens.com for purchase, with a prescription.

    To prevent eye infections, you should only sleep in contact lenses that are FDA-approved for overnight or extended wear. Here are the most popular contact lenses available on Lens.com that are FDA-approved for overnight wear. For more information on overnight wear contacts and our definitive and regularly updated list, read on.

    Why is it risky to sleep in contact lenses that are not FDA-approved for overnight or extended wear?

    Sleeping in contact lenses that are not designed for overnight or extended wear increases your risk of contracting eye infections. Contact lenses absorb moisture from the eyes and sleeping in contact lenses deprives your eyes of much-needed oxygen.

    There are no blood vessels in your corneas, which means they get their oxygen directly from the air. Sleeping in contact lenses prevents your corneas from getting the oxygen it needs to stay healthy. Corneal hypoxia (oxygen deprivation) can lead to corneal warping, scarring, and pain. 

    However, the most significant risk of sleeping in contact lenses not approved for extended wear is eye infections. Your risk of contracting eye infections increases six to eight times when you sleep in your contact lenses.

    Why are some contact lenses FDA-approved for overnight or extended wear while others aren’t?

    The simplest reason why not all contact lenses are FDA-approved for overnight wear is that contact lens manufacturers have to apply for FDA approval. Applying for FDA approval is a lengthy process that requires the submission of studies and research documents as well as passing clinical trials. If a manufacturer wants FDA approval, they’d have to spend a considerable amount of time and resources.

    Another reason is that contact lenses that are designed for overnight wear are made of thinner material compared to daily wear contact lenses. Many contact lens brands that are FDA-approved for overnight wear are also made with silicone hydrogel, which is significantly more breathable than standard hydrogel. Silicone hydrogel allows for much better oxygen transmissibility, which is an important factor when wearing contact lenses for extended periods.

    What is oxygen transmissibility in contact lenses?

    Oxygen transmissibility refers to oxygen’s ability to pass through the contact lens material. The first contact lens materials were impermeable to oxygen. Your corneas need oxygen to stay healthy and hydrated, and wearing contact lenses that prevent the corneas from receiving oxygen can result in complications such as corneal inflammation and eye infections.

    The good news is that there have been plenty of amazing innovations in contact lenses since they were first introduced to the public. Today’s soft contact lenses are made using either hydrogel, which has low to moderate oxygen transmissibility, or silicone hydrogel, which has high oxygen transmissibility.

    Hydrogel contact lenses meet the oxygen requirements (open eye) to avoid corneal complications. Meanwhile, silicone hydrogel contact lenses surpass the oxygen requirements to avoid corneal complications even when the eye is closed.

    Proper Care and Maintenance of Extended-Wear Contact Lenses

    While some contact lenses are approved for extended wear, including overnight use, it’s crucial to maintain them properly to minimize the risk of eye infections and ensure their longevity.

    1. Regular Cleaning: Even if you’re wearing your contact lenses overnight, it’s imperative to clean them daily. Use a recommended solution to rinse and disinfect the lenses before placing them in their case.
    2. Avoid Tap Water: Always use a saline solution or a multi-purpose solution to clean and store your lenses. Tap water can introduce harmful bacteria into your eyes.
    3. Hand Hygiene: Always wash and dry your hands thoroughly before touching your lenses. This will help prevent the transfer of dirt and microorganisms to your eyes.
    4. Regularly Replace Your Lens Case: Your contact lens case can become a breeding ground for bacteria if not replaced regularly. Aim to replace it every three months or as recommended by your ECP.
    5. Follow Replacement Schedule: Always adhere to the replacement schedule for your specific brand or type of contact lenses. Overwearing lenses can lead to complications, even if they feel okay.
    6. Stay Updated with Eye Examinations: Schedule regular check-ups with your ECP. This ensures that any potential problems are caught early and that you’re always using the most suitable lenses for your eyes.
    7. Know the Signs of Trouble: Be aware of symptoms like redness, pain, tearing, increased light sensitivity, blurry vision, or discharge. If you experience any of these, remove your lenses and consult your ECP immediately.
    8. Proper Lens Storage: If you decide not to wear your lenses overnight or take a break from wearing them, ensure they are properly stored in a clean lens case filled with fresh solution.

    By prioritizing the care and maintenance of your extended-wear contact lenses, you can enjoy the convenience they offer while ensuring your eyes remain healthy and comfortable.
