Corneal Oxygen Deprivation: Dangerous Signs Every Contact Lens User Should Know!

Wearing contact lenses has become very popular today, whether for vision correction or as a fashion statement. But did you know that wearing contact lenses for extended periods and not taking proper care of them can cause oxygen deprivation to the cornea?

Oxygen deprivation in the cornea can lead to long-term eye health issues, so it’s important for contact lens wearers to recognize the dangerous signs and know how to prevent oxygen deprivation.

Why Does the Cornea Need Oxygen? How Important Is It for Eye Health?

The cornea is a transparent tissue that filters light to help us see clearly, and it requires oxygen to maintain its transparency and health. However, unlike other tissues in the body, the cornea doesn’t have blood vessels to deliver oxygen. It relies on oxygen from the air and tears to "breathe."

If you wear low-quality contact lenses or keep them in for too long, the cornea doesn’t get enough oxygen, which can negatively affect your eye health. Proper oxygen supply helps keep the cornea clear, strong, and protects it from various eye issues.

The Dangers of Oxygen Deprivation in the Cornea: 5 Signs You Should Watch Out For

If your cornea is deprived of oxygen, you may notice the following symptoms:

• Red Eyes and Increased Risk of Infection Oxygen deprivation makes the cornea weaker, leading to red eyes, which are more susceptible to infection and inflammation.
• Eye Irritation You may feel like there’s dust or foreign objects in your eyes, or experience discomfort, burning, or general unease.
• Blurred Vision Lack of oxygen leads to blurry vision, making your eyes sensitive to light. Bright lights can cause additional pain.
• New Blood Vessels in the Cornea As oxygen deprivation worsens, the cornea may develop new blood vessels to compensate, which can cloud the cornea and worsen long-term vision.
• Dry Eyes and Excessive Tearing Oxygen deprivation can lead to dry eyes, causing your eyes to produce more tears to relieve the irritation, resulting in frequent tearing.

Causes of Oxygen Deprivation in the Cornea: How Risky Is Wearing Contact Lenses for Too Long?

Oxygen deprivation in the cornea can be caused by various factors, most commonly related to wearing contact lenses:

• Wearing Contact Lenses for Extended Periods Wearing contact lenses all day or while sleeping prevents the cornea from getting enough oxygen. If the lenses are of low quality, less oxygen is able to pass through.
• Low-Quality Contact Lenses Some types of contact lenses are made from materials with low oxygen permeability. Over time, the cornea suffers from oxygen deprivation.
• Pre-existing Eye Conditions Those with eye conditions like allergies, diabetes, or problems with tear production are more likely to experience oxygen deprivation in the cornea.
• Corneal Injury or Infection An injured or infected cornea takes longer to heal and is more likely to suffer from oxygen deprivation.

How to Prevent Oxygen Deprivation in the Cornea for Contact Lens Wearers

To protect your eyes and prevent oxygen deprivation, here are some tips for contact lens wearers:

• Witch to Glasses Occasionally Give your eyes a break from contact lenses by wearing glasses occasionally to ensure your eyes get enough oxygen.
• Choose High-Quality Contact Lenses Opt for contact lenses that have high oxygen permeability. High-quality lenses allow more oxygen to reach the cornea and reduce the risk of deprivation.
• Avoid Rubbing Your Eyes Rubbing your eyes can lead to infections and inflammation. If your eyes feel irritated, use artificial tears to soothe them.
• Regular Eye Exams Schedule annual eye exams with an optometrist to detect any early signs of oxygen deprivation or other eye health issues.

Your eyes are one of the most important organs, and taking care of your eye health is crucial. Proper care and selecting quality contact lenses, taking breaks, and scheduling regular eye exams can ensure that your corneas stay healthy. For those who wear contact lenses regularly, remember to choose good lenses, rest your eyes, and stay on top of your eye health to ensure that your vision remains clear and your eyes stay healthy for years to come!
