Can I Sleep In Monthly Contacts?

If you’re a contact lens wearer, you may have wondered if it’s safe to sleep while wearing your monthly lenses. After all, life is busy, and the idea of removing your lenses before bed can seem like a hassle. But is it okay to wear your monthly contacts overnight? In this blog, we’ll explore this commonly asked topic.

What Are Monthly Contacts?

Monthly contact lenses are designed to be worn for up to 30 days. Each night, they are removed, cleaned, and stored in solution until you’re ready to put them back in the next morning. Unlike daily or bi-weekly lenses, monthly lenses are made from materials that allow them to be worn longer. They are a popular choice for people who want both affordability and convenience.

These lenses are durable, maintain their shape over extended use, and provide more comfort throughout the day compared to daily disposable lenses, which must be replaced every 16-24 hours. While monthly contacts are a great option for those on a budget, they require a little more care and attention to keep them clean and maintain their performance.

The key to making monthly lenses work for you is sticking to a regular cleaning and storage routine. The lenses will accumulate deposits from your eyes over time, so it’s crucial to clean them properly to avoid irritation, discomfort, or infection. Regular maintenance lets you enjoy clear vision and comfort every day.

Can You Sleep in Monthly Contacts?

The short answer: it depends. Some monthly lenses are FDA-approved for extended wear, meaning they can be worn overnight for up to six consecutive nights. However, not all monthly lenses are made for overnight use. It’s essential to check the product details or talk with your eye care provider to determine if your lenses are safe for overnight wear.

Extended-wear lenses are made from special materials that allow more oxygen to reach the cornea (which is crucial for eye health). These lenses are specifically designed to be worn while you sleep. This makes them a convenient option for those who need continuous vision correction. But even with extended-wear lenses, it’s important to follow the manufacturer’s guidelines carefully.

If you’re not sure if your lenses can be worn overnight, it’s best to double-check with your optometrist. They can provide you with guidance based on your eye health and help you decide what’s best for your lifestyle.

Risks of Sleeping in Contacts

Although some lenses are designed for extended wear, sleeping in your contacts—especially if they’re not made for overnight use—can significantly increase the risk of eye infections and irritations. Here’s why:

Oxygen Deprivation: When you sleep with your contacts in, the supply of oxygen to your cornea is restricted. The cornea is the clear, dome-shaped surface at the front of the eye, and it relies on oxygen to stay healthy. During sleep, your eyelids are closed, and wearing contacts further reduces the amount of oxygen that reaches your eyes. This can lead to corneal swelling, irritation, and discomfort.

Infections: The warm, moist environment under a contact lens is the perfect breeding ground for bacteria and other microorganisms. Wearing lenses while sleeping increases the risk of infections like conjunctivitis (pink eye) or keratitis (an infection of the cornea). These infections can be painful and may require medical treatment to clear up.

Dryness and Discomfort: Many contact lenses naturally absorb moisture from your eyes, so when you wear them overnight, your eyes may not produce enough moisture to keep them comfortable. This can result in dryness, redness, and irritation the next day.

These risks are why eye care professionals strongly urge you to remove your contacts before sleeping. 

Consulting Your Eye Care Professional

If you’re considering sleeping in your monthly contacts, it’s a good idea to consult your eye care provider first. They can provide personalized advice based on your eye health and determine if your lenses are suitable for overnight wear. Your optometrist can also check for any underlying issues that may increase the risk of complications when sleeping in contacts.

Regular eye exams are essential for maintaining good eye health. Your optometrist can also evaluate how well your lenses are fitting and identify any potential problems before they become serious. For example, if you’re experiencing discomfort or noticing changes in your vision, it might be time for a different type of lens or a new prescription.

How to Properly Care for Your Monthly Contacts

To maximize the lifespan of your monthly lenses and keep your eyes healthy, proper care and cleaning are essential. Here are some tips to help you take care of your lenses:

• Clean Your Lenses Regularly: Every time you remove your contacts, clean them with  high-quality contact lens solution. Never use water to clean your lenses, as it can introduce bacteria and cause infections. The right solution will remove daily deposits from your lenses and disinfect them, reducing the risk of eye irritation.
• Wash Your Hands: Before handling your contacts, wash your hands thoroughly with soap and water. This helps prevent the transfer of bacteria to your lenses and reduces the chance of infection.
• Replace Your Lens Case: Your contact lens case can harbor bacteria over time, so it’s important to replace it regularly. Clean the case with disinfecting solution and allow it to air dry. When storing your lenses, always use fresh solution, and never reuse old solution. 
• Stick to the Replacement Schedule: Monthly lenses should be replaced every 30 days, even if they seem to be in good condition. Mark your calendar and remind yourself to switch to a new pair.
• Avoid Sleeping in Non-Extended Wear Lenses: If your lenses are not designed for extended wear, don’t sleep in them. This will help reduce the risk of oxygen deprivation, dryness, and infection.

Key Takeaways on Sleeping in Monthly Contacts

Frequently Asked Questions About Sleeping in Monthly Contacts

Q: Can I sleep in my monthly contact lenses?

A: It depends on the type of lenses you have. Some monthly contacts are designed for extended wear and are FDA-approved for overnight use. However, not all monthly lenses are suitable for sleeping, so it’s essential to check the product details or consult your eye care professional. If your lenses are not approved for overnight wear, it’s best to remove them before sleeping to avoid eye irritation or infections.

Q: What happens if I sleep in my contacts?

A: Sleeping in contacts that are not designed for overnight wear can reduce the amount of oxygen reaching your cornea. This leads to swelling, discomfort, and an increased risk of eye infections. Bacteria and other microorganisms thrive in the moist environment under your lenses, which may result in conditions like conjunctivitis or keratitis.

Q: How can I tell if my monthly lenses are safe to wear overnight?

A: Check the packaging or product description for any mention of “extended wear” or “overnight wear” approval. If you’re unsure, the best course of action is to ask your eye care provider. They can review your lenses and make recommendations based on your eye health and lifestyle.

Q: Can I wear my lenses while napping?

A: Short naps of an hour or two are generally okay for most people. But if you frequently take naps during the day, make sure that your lenses are comfortable and that your eyes are still getting enough oxygen. If you’re using lenses that aren’t designed for extended wear, it’s better to remove them during naps to avoid the risk of dryness or irritation.

Q: What should I do if I accidentally fall asleep with my contacts in?

A: If you accidentally fall asleep with your lenses in, don’t panic. Gently remove them as soon as you wake up. If your eyes feel dry, irritated, or uncomfortable, apply lubricating eye drops or consult your optometrist. Refrain from wearing your lenses again until your eyes have fully recovered.

Q: How can I avoid the risks of sleeping in contacts?

A: The best way to protect your eyes is by following the instructions for your contact lenses. This includes removing them before bed unless they are made for extended wear. Regular cleaning, replacing your lenses on schedule, and visiting your eye care provider for regular check-ups will also minimize any risks.

Q: Is it safe to wear my monthly lenses for more than 30 days?

A: No, it is not recommended to wear your monthly lenses for longer than 30 days. Over time, lenses accumulate deposits and bacteria that cleaning can’t fully remove. Wearing lenses past their recommended replacement period can cause discomfort and increase the risk of infection. Always follow the replacement schedule provided by your optometrist.

Q: Can I switch to extended wear lenses if I want to sleep in my contacts?

A: Yes, if you’re interested in wearing lenses overnight, your optometrist can recommend extended wear lenses that are designed for this purpose. These lenses allow more oxygen to reach your eyes and are specifically made to be worn for several days at a time. Still, always follow the guidelines for their use.

Q: What’s the best way to clean and store my monthly contact lenses?

A: To keep your lenses in the best condition, always clean them with a high-quality contact lens solution after removing them. Never use water or saliva to clean them, as these can introduce harmful bacteria. Replace your lens case regularly and use fresh solution each time you store your lenses. Be sure to follow your optometrist’s recommendations for cleaning and maintenance.

Q: How can I prevent dry eyes while wearing my contacts?

A: Dry eyes are a common issue for contact lens wearers, but there are a few things you can do to reduce discomfort. Use lubricating eye drops as recommended by your optometrist, take regular breaks from screens, and stay hydrated. If discomfort persists, your eye care provider may suggest a different type of lens or a more suitable cleaning solution.
