Can You Take Naps With Contacts In?

Sleeping or napping with contacts in can cause serious eye irritation and increase the risk of infections.

Understanding the Risks of Napping With Contacts

Taking a quick nap while wearing contact lenses might seem harmless, but it carries significant risks. Contact lenses sit directly on the eye’s surface, limiting oxygen flow to the cornea. When eyes are closed during sleep or even a short nap, oxygen delivery decreases even further, creating a low-oxygen environment. This can lead to discomfort, dryness, and potentially dangerous complications.

The most common problems linked to sleeping or napping with contacts include corneal hypoxia (lack of oxygen), increased bacterial growth, and dry eyes. Corneal hypoxia can cause swelling of the cornea, blurred vision, and discomfort. If bacteria find their way trapped under the lens during sleep, it can lead to infections such as keratitis—an inflammation of the cornea that may threaten vision if untreated.

Even short naps can cause these issues because the closed eyelids restrict oxygen supply and trap moisture under the lens. The longer your eyes stay shut with contacts in place, the higher the risk becomes. It’s important to understand that not all lenses are created equal; some are designed for extended wear, but even those have limits.

How Contact Lenses Affect Eye Health During Sleep

Contact lenses act as barriers between your eye and the surrounding environment. While designed to be breathable, they still reduce oxygen transmission compared to open eyes. The cornea relies heavily on atmospheric oxygen since it has no blood vessels.

When you close your eyes for sleep or a nap, oxygen exchange drops dramatically—approximately 90% less than when eyes are open. This reduction is compounded by contact lenses sitting directly on the corneal surface.

This low-oxygen state causes:

Corneal swelling: The cornea absorbs water and swells when deprived of oxygen.
Reduced tear exchange: Tears help flush out debris and bacteria; lenses limit this action.
Bacterial buildup: Closed eyelids with lenses create a warm, moist environment ideal for bacterial growth.

These changes can lead to symptoms like redness, itching, burning sensation, blurry vision, and increased sensitivity to light.

Extended Wear Lenses vs Daily Wear Lenses

Some contact lenses are FDA-approved for extended wear—meaning they can be worn continuously for several days or nights without removal. These lenses are made from materials that allow higher oxygen permeability.

However:

Extended wear lenses still carry risks if worn beyond recommended durations.
Not everyone’s eyes tolerate extended wear equally; some develop irritation or infections despite using approved lenses.
Daily wear lenses are not designed for overnight use and should be removed before sleeping or napping.

Even with extended wear lenses, it’s best practice to avoid sleeping with them unless specifically advised by your eye care professional.

The Dangers of Sleeping or Napping With Contacts In

Sleeping in contact lenses increases your chances of developing serious eye conditions. Below is a detailed look at some dangers:

1. Microbial Keratitis

Microbial keratitis is an infection caused by bacteria, fungi, or parasites invading the cornea. It often results from poor lens hygiene combined with overnight wear.

Symptoms include:

Severe eye pain
Redness and swelling
Poor vision
Discharge from the eye

If untreated, microbial keratitis may cause scarring or permanent vision loss.

2. Corneal Ulcers

Ulcers are open sores on the cornea caused by infection or trauma. Sleeping in contacts increases risk because bacteria thrive in low-oxygen conditions behind the lens.

Corneal ulcers require urgent medical attention and prolonged treatment with antibiotics or antifungal medications.

3. Giant Papillary Conjunctivitis (GPC)

GPC is an inflammatory reaction triggered by mechanical irritation from contact lenses worn too long without removal. Symptoms include itching, mucus discharge, and lens intolerance.

Napping with contacts regularly worsens this condition by increasing friction between lens and conjunctiva during closed-eye periods.

The Science Behind Oxygen Permeability and Contact Lenses

Oxygen permeability (Dk) measures how much oxygen passes through lens material per unit thickness. Higher Dk values indicate better oxygen flow to the cornea.

However:

The actual oxygen reaching your eye depends on both Dk value and lens thickness.
Lenses with high Dk but thick profiles may still limit oxygen supply.
Softer silicone hydrogel lenses generally have higher Dk values than traditional hydrogel ones.

Here’s a table comparing common contact lens types based on material and typical oxygen permeability:

Lens Type	Material	Dk Value (Oxygen Permeability)
Traditional Hydrogel	Hydroxyethyl methacrylate (HEMA)	20 – 40
Silicone Hydrogel (Soft)	Silicone + Hydrogel blend	86 – 175+
Rigid Gas Permeable (RGP)	Semi-rigid plastic materials	30 – 175+
Scleral Lenses (RGP type)	Larger diameter RGPs covering sclera	High – varies by design
Scleral Lenses (Hybrid)	Scleral + soft skirt combination	Varies widely depending on materials used

Even high-Dk lenses cannot fully compensate for reduced oxygen during sleep if worn continuously without breaks.

Sleeping or napping with contacts limits oxygen supply to the cornea by about 90%, creating a low-oxygen environment. This can result in corneal swelling, reduced tear exchange, and increased bacterial growth under the lenses.

Are Some Contact Lenses Safer for Napping Than Others?

Some lenses are FDA-approved for extended wear and allow higher oxygen flow. However, even these lenses have limits, and napping with any contact lenses still carries risks that should be considered carefully.

What Should You Do If You Accidentally Nap With Contacts In?

If you accidentally nap with contacts in, remove them as soon as possible and rinse your eyes with sterile saline if irritation occurs. Monitor for redness or discomfort and consult an eye care professional if symptoms persist.

Caring For Your Eyes: Best Practices Around Napping With Contacts In

It’s simple: avoid sleeping or napping in daily wear contact lenses altogether. Here are some practical tips to keep your eyes healthy:

If you feel sleepy: Remove your contacts before lying down—even if it’s just a short nap.
Create a routine: Always remove contacts at night unless prescribed extended wear ones.
If you must nap unexpectedly: Use lubricating eye drops before removing contacts if possible to ease dryness afterward.
Avoid wearing contacts longer than recommended: Follow manufacturer guidelines strictly.
If you experience discomfort after napping in contacts: Remove them immediately and consult an eye care professional if symptoms persist.
Avoid swimming or showering with contacts on:This increases infection risk similar to sleeping in them due to waterborne microbes.
Mistake-proof storage:If you remove contacts before naps regularly but sometimes forget putting them back in afterward—consider keeping glasses handy as backup eyewear.
Mouth off bad habits:If you tend to fall asleep unintentionally wearing contacts—try setting reminders or alarms as prompts to remove them beforehand.
Mental note:Your eyes need rest too! Giving them breaks from contacts helps maintain long-term comfort and health.
Treat infections seriously:If redness or pain occurs after napping with contacts—seek prompt medical attention instead of self-medicating.
Blink often when awake:This helps keep tears flowing naturally around your lenses preventing dryness caused by reduced tear exchange during sleep periods.
Avoid rubbing your eyes harshly after naps in contacts:
Keeps hands clean before handling lenses:

The Role of Eye Care Professionals Regarding Contact Lens Use During Sleep/Naps

Eye doctors emphasize patient education about risks linked with improper contact lens use including sleeping/napping habits. They recommend scheduling regular exams every six months—or more frequently if problems arise—to monitor corneal health closely.

Professionals may suggest switching lens types based on lifestyle needs:

If napping frequently while wearing daily disposables causes irritation—they might prescribe silicone hydrogel options or hybrid designs offering better breathability.
If patients insist on overnight use—specialized extended-wear designs may be considered under strict supervision ensuring minimal complications occur through periodic monitoring including slit lamp exams assessing corneal integrity post-sleep cycles.

Lenses fitted specifically for dry eyes may help reduce discomfort related to decreased tear exchange during closed-eye periods wearing contacts which intensify dryness symptoms especially post-nap
