Can You Sleep in Monthly Contacts? A Buyer’s Guide to 30 Day Contact Lenses


Whether you already use contacts or are considering them for the first time, monthly disposable contact lenses (also known as monthlies or 30 day lenses) offer significant advantages, including cost savings, comfort, and sustainability.

In this in-depth monthly contact lenses buyer’s guide, we’ll discuss what makes 30 day lenses an excellent option for vision correction to help you make an informed decision that best suits your needs and lifestyle.

What Are Monthly Contact Lenses?

Monthly contacts are lenses designed for wear (daily or extended) for up to 30 days. Unlike daily disposable contacts that require a fresh pair every day, monthly contacts can be worn throughout the day and then cleaned and stored overnight in contact lens solution. This routine is repeated for about a month before the lenses need to be replaced.

What sets monthlies apart from dailies or weeklies is their blend of convenience and sustainability. Monthlies are made from lens materials that allow more oxygen to reach the cornea and retain oxygen. This promotes enhanced comfort and better overall eye health. Their replacement schedule also means you only need to buy one pair of contacts every month.

As such, choosing monthly contacts can be a smart decision for both regular and occasional contact lens wearers who seek a balance between practicality and cost efficiency. They reduce the environmental burden with fewer lenses and packaging waste compared to daily disposables.

What Are the Benefits of Monthly Contact Lenses?

Monthly contact lenses offer several advantages that make them a preferred choice for many contact lens wearers. Here’s why they stand out:

1. Cost-Effectiveness

Monthlies are generally more economical in the long run compared to daily or bi-weekly disposables. By using only one pair of lenses for an entire month, you reduce the cost per wear. This makes monthly contacts a budget-friendly option for regular users.

2. Reduced Environmental Impact

With fewer lenses used and less packaging waste, monthlies are a more sustainable choice. This waste reduction contributes to a smaller environmental footprint and may appeal to eco-conscious consumers.

3. Enhanced Comfort

Advanced lens materials used in monthly contacts (e.g., silicone hydrogel) allow for better oxygen permeability and moisture retention. This means they can be more comfortable for your eyes, especially if you suffer from eye dryness or discomfort during lens wear.

4. Durability

Monthly contacts are designed to withstand daily wear and handling for up to 30 days better than daily or bi-weekly disposable contacts. While this means monthly contacts may be slightly thicker than frequent replacement lenses, it makes them ideal for users who value durability.

5. Convenience

Though monthly contacts require regular cleaning, the routine is simple and straightforward — remove, rinse, and store. This small daily effort is a trade-off many are willing to make for the benefit of not having to open a new pair of contacts every day.

What to Consider Before Buying Monthly Contact Lenses

When considering monthly contact lenses as your choice for vision correction, there are several factors to take into account to ensure they are the right fit for your lifestyle and eye health needs:

1. Eye Health

It’s essential to have a comprehensive eye exam when considering contacts. Only an eye care professional (ECP) can determine if your eyes are suited for monthly lenses, particularly if you have conditions like dry eyes or astigmatism, which may require specific lens types.

2. Lifestyle Needs

Consider how contact lenses fit into your daily activities. Monthly lenses are ideal for those who can commit to a consistent cleaning routine. If you have a hectic schedule, travel frequently, or tend to fall asleep with your lenses on, you might need lenses with higher flexibility or extended wear capabilities.

3. Maintenance Commitment

Monthlies require regular cleaning and proper storage to prevent eye infections and maintain lens performance. Assess whether you are ready to adopt this routine:

  • Daily cleaning and rinsing with a recommended solution.
  • Regularly replacing the storage case to prevent bacterial growth.
  • Using only fresh solution in the lens case, never tap water or saliva.

4. Comfort Preferences

While monthlies are designed for comfort, individual preferences and sensitivities vary. Some wearers might prefer the ultra-thin feel of daily or bi-weekly disposables or the specific material properties of rigid gas-permeable (RGP) contacts.

5. Consultation With Eye Care Professionals

Regular follow-ups with your optometrist or ophthalmologist can help monitor your eye health and ensure that your monthly lenses are still the best option. They can also provide tips tailored to your specific health needs and lifestyle.

How to Care for Monthly Contact Lenses

Proper care and maintenance are crucial for the longevity and performance of your monthly contact lenses. This section of our monthly contacts buyer’s guide outlines simple steps to ensure your lenses stay clean and your eyes healthy:

  2. Rinsing – Rinse each lens thoroughly with a sterile contact lens solution recommended by your eye care provider. This step removes loosened debris and prepares the lenses for safe storage.
  3. Storage – Place each lens in a clean lens case filled with fresh solution. Ensure the lenses are completely submerged.
  4. Case Care – Rinse your lens case with fresh solution — never water — and leave it open to air dry. Replace your lens case at least once every three months to reduce the risk of contamination.
  5. Regular Check-Ups – Visit your ECP regularly to keep your prescription up-to-date and ensure your eyes are healthy. Your ECP can provide personalized advice about your lens care routine if needed.
