Here’s why you should avoid napping in contact lenses:

– Extended Wear Lenses: Extended wear lenses are specially designed to be worn overnight and are approved for use while sleeping. These lenses are made from materials that promote higher oxygen permeability, allowing your eyes to breathe even during sleep.

– Regular Contact Lenses: Regular contact lenses, intended for daily wear, have lower oxygen permeability and can decrease the oxygen supply to your corneas, especially when your eyes are closed during sleep. This can lead to discomfort, dryness, and other complications.

6.2 Risks of Sleeping in Contacts:

Sleeping in contact lenses increases the risk of various eye conditions due to decreased oxygen flow and the potential for bacterial or viral contamination. Here are some risks associated with sleeping in contacts:

– Decreased Oxygen Flow: During sleep, your eyes receive less oxygen because the closed eyelids restrict air circulation.

When contacts are worn, they further limit the amount of oxygen reaching the corneas. This oxygen deprivation can lead to discomfort, redness, and an increased risk of complications.

– Bacterial and Viral Infections: Extended contact lens wear, especially during sleep, can promote bacterial and viral growth on the lenses and increase the risk of eye infections. These infections can range from mild conjunctivitis (pink eye) to more severe conditions that require medical intervention.

– Inflammation of the Cornea: Prolonged contact lens wear, including while sleeping, can lead to chronic inflammation of the cornea. This can cause redness, discomfort, and blurred vision, potentially affecting the long-term health of your eyes.

– Corneal Neovascularization: Insufficient oxygen supply to the corneas can result in the growth of new blood vessels, a condition known as corneal neovascularization. This can lead to vision problems and potentially compromise the overall health of your eyes.

In conclusion, it is important to follow the recommended wearing time and schedule provided by your eye care professional when first starting to wear contact lenses. By gradually increasing the duration of wear, you allow your eyes to adapt comfortably.

However, it is best to remove contact lenses before napping or sleeping, as this reduces the risk of discomfort, eye infections, and potential long-term complications.

7) Harmful Effects of Sleeping in Contacts:

7.1 Oxygen Deprivation and Eye Health:

Ensuring a steady supply of oxygen is crucial for maintaining healthy eyes. When we sleep, our eyes naturally receive less oxygen due to closed eyelids.

However, sleeping in daily wear contact lenses further restricts the flow of oxygen, potentially leading to various eye health issues. Here’s why sleeping in daily wear lenses can be harmful:

– Reduced Oxygen Permeability: Regular contact lenses, designed for daily wear, have a lower oxygen permeability compared to lenses specifically approved for extended wear or continuous overnight use.

This restricted oxygen flow deprives the corneas of the necessary oxygen supply, impairing their health and function. – Corneal Hypoxia: Corneal hypoxia refers to the lack of oxygen in the corneas.

When you sleep in daily wear lenses, the corneas receive even less oxygen than they would during the day, which can result in redness, discomfort, and dryness. Prolonged corneal hypoxia can lead to more serious complications.

– Risk for Corneal Ulcers: The combination of decreased oxygen and added lens wear during sleep can increase the risk of developing corneal ulcers. These painful open sores on the surface of the cornea may result from bacterial or fungal infections, potentially leading to severe vision loss if left untreated.

7.2 Increased Risks Associated with Sleeping in Contacts:

Sleeping in contact lenses elevates the risks of several eye complications, primarily due to decreased oxygen flow and the potential for bacterial or microbial contamination. Here are some increased risks associated with sleeping in contacts:

– Eye Infections: Wearing contact lenses while sleeping increases the chance of developing eye infections, including bacterial and microbial keratitis.

These infections can lead to redness, pain, and vision problems. If left untreated, they can cause permanent damage to the cornea and even result in vision loss.

– Inflammation of the Cornea: Prolonged contact lens wear, particularly during sleep, can lead to chronic inflammation of the cornea, called keratitis. Inflammation can cause discomfort, excessive tearing, reduced visual acuity, and hypersensitivity to light.

It is essential to address these symptoms promptly to prevent further complications. – Corneal Neovascularization: Insufficient oxygen supply to the corneas can trigger a condition called corneal neovascularization.

This occurs when new blood vessels grow into the cornea as a response to low oxygen levels. The presence of these abnormal blood vessels not only compromises vision but also increases the risk of infections and other corneal disorders.

– Increased Lens Deposits: Sleeping in contact lenses can cause a buildup of deposits on the lens surface, such as protein, lipids, and debris from the tear film. These deposits can lead to discomfort, reduced vision clarity, and create a breeding ground for harmful bacteria.

Regular cleaning and disinfection are crucial, but removing the lenses before sleep provides an opportunity for your eyes to breathe and clear these deposits naturally. In conclusion, sleeping in contact lenses designed for daily wear is not recommended due to the associated risks and potential harm to eye health.

Reduced oxygen permeability during sleep can lead to corneal hypoxia, increasing the likelihood of corneal ulcers and other complications. Moreover, the risk of eye infections, inflammation of the cornea, and corneal neovascularization is heightened when contacts are worn continuously during sleep.

It is crucial to prioritize eye health and adhere to recommended wearing schedules and care routines advised by your eye care professional. By removing your contact lenses before sleeping, you can mitigate these risks and maintain optimal eye health.

In conclusion, it is imperative to prioritize the health and well-being of our eyes when it comes to wearing contact lenses. Gradually increasing the duration of wearing contacts, following a recommended schedule provided by an eye doctor, and avoiding napping or sleeping in contacts are crucial steps in maintaining optimal eye health.

Sleeping in daily-wear lenses can lead to oxygen deprivation, an increased risk of eye infections, inflammation of the cornea, and corneal neovascularization. By taking these precautions and being mindful of proper contact lens care, we can minimize the risks and ensure a comfortable and safe contact lens-wearing experience.
