What You Need to Know About Contact Lens Intolerance

For millions of people, contact lenses are a convenient and comfortable alternative to glasses. However, some individuals experience discomfort or even pain when wearing them, a condition known as contact lens intolerance (CLI). A vision therapy clinic discusses what you need to know about this condition.

What Is Contact Lens Intolerance?

Contact lens intolerance occurs when your eyes can no longer comfortably tolerate wearing contact lenses. While some people develop CLI over time after years of wearing lenses, others may experience symptoms after just a short period. CLI can result from a variety of factors, including changes in your eye health, the lenses themselves, or environmental conditions.

Common Causes of CLI

Dry Eye Syndrome: One of the most common causes of CLI is dry eye syndrome. Contact lenses can aggravate dry eyes by reducing the amount of oxygen reaching the cornea and causing further irritation.

Allergies: Seasonal or environmental allergies can make contact lenses uncomfortable by increasing eye sensitivity and irritation.

Lens Materials: Some people may react to the materials or solutions used with their contact lenses. Newer lenses made from silicone hydrogel offer better oxygen flow but might not suit everyone.

Improper Care: Failing to properly clean or replace your lenses can lead to discomfort. Over time, protein deposits can build up on the lenses, leading to irritation and intolerance.

Symptoms of Contact Lens Intolerance

• Persistent eye discomfort
• Redness or swelling
• Itchy, dry, or watery eyes
• Blurry vision
• A gritty or foreign body sensation

If you experience any of these symptoms, it’s important to consult your optometrist to determine the cause and explore potential solutions like vision therapy.

Managing and Preventing CLI

While contact lens intolerance can be frustrating, it’s often manageable. Your optometrist can recommend several strategies to help you get back to wearing your lenses comfortably.

Switching to Daily Disposable Lenses: Daily disposable lenses reduce the risk of buildup and offer a fresh start each day, which may alleviate symptoms.

Using Artificial Tears: Preservative-free artificial tears can help combat dryness and provide moisture to the eyes, making lenses more tolerable.

Trying Different Lens Materials: If you’re sensitive to a particular type of lens, switching to a different material, such as silicone hydrogel or gas-permeable lenses, may improve comfort.

Taking Breaks: Giving your eyes regular breaks from contact lenses can help reduce symptoms of intolerance. Try alternating between lenses and glasses.
