For many of us, the idea of popping in a pair of contact lenses and forgetting about them is a dream come true. Imagine no more fumbling for your glasses first thing in the morning or worrying about removing your lenses after a long day. But is it really safe to sleep in your contact lenses? Let’s dive in and find out.

Understanding the Basics

First off, there’s a distinction to be made between traditional contact lenses and those specifically designed for extended or overnight wear. Not all lenses are created equal, and it’s essential to know the difference.

Extended Wear Contact Lenses

These are the stars of the show when it comes to overnight use. Extended wear contact lenses are specially designed to be worn continuously for several days—some even up to a week or 30 days! These lenses are made of materials that allow a high amount of oxygen to reach the eyes, a critical component in maintaining eye health.

Popular brands and types of extended-wear lenses include:

  1. Acuvue Oasys with Hydraclear Plus: These can be worn continuously for up to a week.
  2. Air Optix Night & Day Aqua: Boasting a longer wear time, these lenses can be worn for up to 30 days and nights continuously.
  3. Biofinity: considered one of the best values in contacts, these are 30 day lenses that can be worn overnight.
  4. ULTRA for Presbyopia: one of a handful of contacts for wearers with presbyopia and are also approved for overnight wear.
  5. Air Optix Plus HydraGlyde for Astigmatism: one of the few contacts that treat astigmatism and can also be worn overnight.

Daily Wear Contact Lenses

These lenses are not designed for overnight wear. They are intended to be removed every night and cleaned thoroughly to keep your eyes safe. Sleeping in daily wear contacts can increase the risk of eye infections, reduced oxygen to the eyes, and other complications.

The Benefits of Extended Wear Lenses

  • Convenience: Without the daily on-and-off routine, extended wear lenses are a boon for those with busy lifestyles.
  • Ideal for Varying Schedules: For those who work night shifts or have erratic sleeping schedules, these lenses can be a great fit.
  • Vision Readiness: No more reaching for glasses when you hear a bump in the night or want to read a late-night message.

Precautions to Consider

While extended-wear lenses offer convenience, it’s essential to be aware of the risks associated with prolonged wear:

  • Eye Infections: Extended wear, even with the right kind of lenses, can increase the risk of eye infections. Always ensure your hands are clean when handling them, and follow your optometrist’s recommendations.
  • Reduced Oxygen: Even though these lenses are designed for higher oxygen permeability, there’s still a chance of reduced oxygen flow, which can lead to complications.
  • Regular Check-ups: To ensure that your eyes remain healthy, frequent visits to your optometrist are vital.


For those who wish to simplify their eye care routine, extended wear contact lenses can be a game-changer. However, as with any medical device, it’s crucial to prioritize your health and safety. Always consult with an optometrist before making a decision, and ensure you’re equipped with the knowledge and habits to make your extended wear experience both convenient and safe.
