Contact lenses have revolutionized vision correction for millions of people, offering convenience and freedom from glasses. However, the question often arises: “Can you sleep with contacts in?” The short answer is no. Sleeping with contact lenses in can pose significant risks to your eye health. This blog delves into the dangers, potential complications, and safe practices for wearing contacts.
Is Sleeping With Contacts Safe?
Sleeping with contact lenses is generally not safe unless specifically prescribed by your eye care professional. Even in such cases, extended wear lenses must be used cautiously. The eyes require oxygen to remain healthy, and wearing contacts overnight reduces oxygen supply to the cornea. This can lead to discomfort, infections, and more severe complications if not addressed promptly.
Why Is It Dangerous to Sleep With Contacts In?
- Reduced Oxygen Supply: Contact lenses create a barrier that limits oxygen flow to the cornea. During sleep, when your eyes are closed, this oxygen supply is further diminished.
- Increased Risk of Infection: Warm, moist environments are breeding grounds for bacteria and other microorganisms. Sleeping with contacts creates a perfect environment for infections.
- Corneal Damage: Prolonged wear can cause microscopic abrasions on the cornea, making it easier for bacteria or fungi to invade.
What Happens If You Sleep With Contacts In?
If you sleep with contacts in, you may wake up with discomfort, redness, or blurred vision. In worse cases, infections like bacterial keratitis, acanthamoeba keratitis, or fungal keratitis can occur.
a) Bacterial Keratitis
Bacterial keratitis is one of the most common and severe eye infections caused by sleeping with contacts. Statistics reveal that individuals who sleep with their lenses are 6-8 times more likely to develop bacterial keratitis than those who don’t. Symptoms include:
- Pain and redness
- Light sensitivity
- Blurry vision
Without prompt treatment, this condition can lead to permanent vision loss.
b) Acanthamoeba Keratitis
Acanthamoeba keratitis is caused by a microscopic organism found in water sources like tap water and swimming pools. Sleeping with contacts increases the risk of this rare but devastating infection. It’s estimated that 85% of cases are linked to improper contact lens hygiene, including overnight wear. Symptoms include:
- Severe pain
- Excessive tearing
- Sensitivity to light
c) Fungal Keratitis
Fungal keratitis occurs when fungi penetrate the cornea, often due to prolonged contact lens wear. The condition is particularly prevalent in warm and humid climates. Fungal keratitis can cause:
- Severe inflammation
- Vision impairment
- Scarring of the cornea
According to the Centers for Disease Control and Prevention (CDC), improper use of contact lenses accounts for up to 25% of microbial keratitis cases worldwide.
What If You Accidentally Fall Asleep Wearing Contacts?
Accidentally falling asleep with contacts in occasionally may not cause severe harm, but it can still lead to discomfort and potential complications. If this happens:
- Do Not Panic: Avoid immediately removing your lenses. This could cause corneal abrasions.
- Rehydrate Your Eyes: Use a sterile saline solution or rewetting drops to moisten your lenses.
- Remove Lenses Carefully: Once your eyes feel lubricated, gently remove the lenses.
- Inspect for Irritation: Check for redness, pain, or blurry vision. If symptoms persist, consult an eye care specialist immediately.
How to Wear Contacts Safely?
To minimize risks and maintain optimal eye health, follow these safety tips:
- Adhere to Wearing Schedules: Only wear your contacts for the duration recommended by your eye care provider.
- Use Proper Hygiene: Wash your hands thoroughly before handling lenses.
- Disinfect Lenses Regularly: Use the appropriate contact lens solution and never reuse old solution.
- Avoid Water Exposure: Remove lenses before swimming or showering.
- Replace Lenses as Directed: Dispose of daily lenses after one use and replace monthly or bi-weekly lenses as instructed.
- Schedule Regular Eye Exams: Visit your eye care professional annually to ensure your eyes remain healthy.
Eye Health Statistics & Facts
- 1 in 500 contact lens users develops a serious eye infection annually, according to the CDC.
- Improper contact lens hygiene is linked to 40-90% of contact lens-related complications.
- Oxygen permeability of the lens material plays a significant role in corneal health. Higher oxygen-permeable lenses reduce the risk but do not eliminate it.
- Contact lens-related microbial keratitis costs the U.S. healthcare system approximately $175 million annually.
Conclusion
Sleeping with contacts in can lead to severe complications, ranging from discomfort to vision-threatening infections. While occasional accidents may not result in immediate harm, habitual overnight wear significantly increases the risks. Always prioritize proper hygiene, adhere to recommended schedules, and consult your eye care professional regularly. By taking these precautions, you can enjoy the benefits of contact lenses while protecting your eye health.
