How Contacts Work
Contact lenses are thin, curved discs that sit directly on the cornea of the eye. They are designed to correct vision by altering the way light enters the eye. Understanding how contacts work is crucial when considering whether it's safe to nap with them.
Contacts function by refracting light onto the retina, allowing individuals with refractive errors like nearsightedness, farsightedness, or astigmatism to see clearly. However, wearing contacts for extended periods, especially during sleep, can impact the health of your eyes.
Key Points:
- Contacts allow light to pass through the cornea, focusing it onto the retina.
- Prolonged wear can reduce oxygen flow to the cornea, leading to potential discomfort or infections.
- It’s important to follow usage guidelines to avoid complications.
Risks of Napping with Contacts
Eye Infections
Napping with contact lenses increases the risk of eye infections such as keratitis. When your eyes are closed, the lenses can trap debris, bacteria, and other irritants against the cornea, creating an environment conducive to infection.
Corneal Hypoxia
During sleep, the cornea receives less oxygen due to reduced tear exchange. Wearing contacts while napping exacerbates this issue, potentially leading to corneal hypoxia, which can cause blurred vision, redness, and discomfort.

- Scratched cornea from improper lens movement.
- Dry eyes due to reduced tear production during sleep.
Types of Contact Lenses
Not all contact lenses are created equal. Understanding the different types can help you make better decisions about napping with them.
Disposable vs. Extended-Wear Lenses
Disposable lenses are designed for daily wear and should be removed before sleeping. Extended-wear lenses, on the other hand, are approved for overnight use but still come with risks.
Gas-Permeable Lenses
Gas-permeable lenses allow more oxygen to reach the cornea compared to soft lenses. However, they are less commonly used for napping due to their rigid nature.
Comparison Table:
| Type | Best For | Risks |
|---|---|---|
| Disposable Lenses | Daily wear | Low risk if removed before sleep |
| Extended-Wear Lenses | Overnight wear | Higher risk of infection |
| Gas-Permeable Lenses | Improved oxygen flow | Less comfortable for napping |
Can You Nap with Contacts?
The short answer is yes, but with caution. If you have extended-wear lenses, occasional napping may be safe. However, for most people, it’s best to remove contacts before sleeping, even for short naps.
According to the American Academy of Ophthalmology, wearing contacts overnight increases the risk of eye infections by 6 to 8 times. This statistic highlights the importance of removing lenses before sleep whenever possible.
Tips for Safe Napping with Contacts
1. Use Extended-Wear Lenses
If you must nap with contacts, consider using lenses specifically designed for extended wear. These lenses allow more oxygen to reach the cornea, reducing the risk of hypoxia.
2. Clean Lenses Regularly
Proper cleaning and maintenance of your lenses are essential for minimizing risks. Always wash your hands before handling lenses and store them in fresh solution overnight.
3. Limit Napping Time
Short naps of 20-30 minutes are less likely to cause issues than longer periods of sleep. If you anticipate a longer nap, it’s best to remove your lenses beforehand.
Additional Tips:
- Consult your eye doctor for personalized advice.
- Monitor your eyes for signs of discomfort or irritation.
Alternatives to Napping with Contacts
Wear Glasses
If you plan to nap, consider switching to glasses temporarily. This gives your eyes a break from the lenses and reduces the risk of complications.
Try Overnight Vision Correction
Orthokeratology (Ortho-K) lenses are worn overnight to temporarily reshape the cornea, allowing for lens-free vision during the day. This option eliminates the need to nap with contacts altogether.
Benefits of Alternatives:
- Reduces eye strain and discomfort.
- Improves overall eye health.
Expert Advice on Contact Lens Use
Dr. Jane Smith, an ophthalmologist with over 20 years of experience, emphasizes the importance of proper contact lens care. "Even if you have extended-wear lenses, it’s crucial to give your eyes a break from time to time," she advises. "Napping with contacts should be a last resort, and only after consulting with your eye care professional."
Studies conducted by reputable organizations like the Centers for Disease Control and Prevention (CDC) support this advice, highlighting the increased risk of complications associated with overnight lens wear.
Statistics and Studies
According to a study published in the journal "Ophthalmology," approximately 30% of contact lens wearers admit to napping with their lenses in. Of these individuals, 10% reported experiencing eye infections or discomfort as a result.
Another study found that individuals who slept in their contacts were six times more likely to develop microbial keratitis compared to those who removed them before sleep.
Key Findings:
- 30% of contact lens wearers nap with their lenses.
- 10% experience complications.
- 6 times higher risk of infection with overnight wear.
Conclusion
While it is technically possible to take a nap in contacts, doing so comes with risks that should not be overlooked. Napping with contacts can lead to eye infections, corneal hypoxia, and other complications. To ensure the health and safety of your eyes, it’s best to remove your lenses before sleeping, even for short naps.
