What Happens If You Wear Contacts Too Long? The Risks of Extended Wear
Wearing contact lenses for longer than recommended can lead to a range of uncomfortable and potentially serious eye problems. Understanding these risks is crucial for maintaining good eye health and preventing long-term damage. This article will explore the potential consequences of extended contact lens wear, addressing common questions and concerns.
What are the risks of wearing contacts for too long?
The risks associated with wearing contacts beyond the prescribed wear time vary depending on the type of contact lenses (daily disposables, extended wear, etc.) and the individual's eye health. However, some common consequences include:
-
Corneal Ulcers: These are open sores on the cornea (the clear front part of your eye) and are a serious complication. Prolonged contact lens wear can deprive the cornea of oxygen, creating an environment where bacteria can thrive and lead to infection. Corneal ulcers can cause severe pain, blurry vision, and even vision loss if left untreated.
-
Giant Papillary Conjunctivitis (GPC): This is an inflammatory condition of the conjunctiva (the membrane lining the eyelid and covering the white part of the eye). It's often triggered by prolonged contact lens wear and can cause itching, redness, and a gritty feeling in the eye. In severe cases, it can lead to blurry vision.
-
Contact Lens-Related Dry Eye: Even with the most comfortable lenses, prolonged wear can disrupt your eye's natural tear film, resulting in dry, irritated eyes. Symptoms include burning, stinging, and a feeling of dryness or grittiness.
-
Bacterial Infections: Bacteria can accumulate on contact lenses worn for too long, leading to various infections. These infections can range in severity from mild discomfort to serious vision-threatening conditions.
-
Microbial Keratitis: A severe infection of the cornea that can lead to scarring and vision loss. This is a serious complication that requires immediate medical attention.
How long is too long to wear contacts?
The answer depends entirely on the type of contact lenses you have and your ophthalmologist's recommendations. Always follow your eye doctor's instructions carefully.
-
Daily disposable lenses: These are designed for single-day use and should be removed and discarded at the end of each day. Wearing them overnight significantly increases the risk of infection.
-
Extended-wear lenses: Some contact lenses are FDA-approved for extended wear, meaning they can be worn overnight. However, even with extended-wear lenses, there are still risks associated with prolonged wear, and it's crucial to follow your eye doctor's guidelines regarding how many nights you can safely wear them.
-
Conventional lenses: These lenses, such as monthly or bi-weekly disposables, require daily removal and cleaning. Sleeping in these lenses significantly increases the risk of infection and complications.
What are the symptoms of problems caused by wearing contacts too long?
Symptoms can vary depending on the problem but often include:
-
Redness and irritation: This is a common sign of eye irritation and could indicate infection or inflammation.
-
Blurry vision: This may be a sign of corneal damage or infection.
-
Pain or discomfort: Sharp pain, burning, or stinging sensations are serious symptoms and require immediate attention.
-
Excessive tearing or dry eyes: These symptoms can indicate irritation or damage to the eye's surface.
-
Sensitivity to light: Increased sensitivity to light (photophobia) can be a symptom of infection or inflammation.
-
Discharge or mucus: This is a sign of potential infection.
What should I do if I think I've worn my contacts too long?
If you experience any of these symptoms, immediately remove your contact lenses and contact your eye doctor. Don't wait to see if the problem goes away on its own. Prompt treatment is essential to prevent permanent damage.
Can wearing contacts too long cause permanent vision loss?
In severe cases, yes. Corneal ulcers and infections, if left untreated, can lead to scarring and permanent vision loss.
This information is for general knowledge and does not constitute medical advice. Always consult with your ophthalmologist for personalized advice regarding contact lens wear and care. They can assess your individual eye health and provide specific recommendations based on your needs and the type of contact lenses you use. Remember, preventing problems is far easier than treating them! Prioritize proper contact lens hygiene and follow your eye doctor's instructions meticulously.
