What Happens If You Wear Your Contacts for Too Long? The Risks of Extended Wear
Wearing contact lenses for longer than recommended can lead to a range of serious eye problems. While the convenience of contacts is undeniable, understanding the potential consequences of prolonged wear is crucial for maintaining healthy eyes. This article will explore the risks associated with exceeding the prescribed wear time for your contact lenses, addressing common questions and concerns.
What are the risks of wearing contacts too long?
The risks of wearing contacts for too long are significant and can range from mild discomfort to severe vision impairment. Prolonged wear deprives your cornea (the clear front part of your eye) of sufficient oxygen, leading to a cascade of potential problems. These include:
- Corneal hypoxia: This lack of oxygen weakens the cornea, making it more susceptible to infection and damage.
- Dry eyes: Extended contact lens wear can significantly dry out your eyes, causing discomfort, irritation, and blurred vision.
- Giant papillary conjunctivitis (GPC): This is an inflammatory condition characterized by the growth of large papillae (bumps) on the conjunctiva (the membrane lining the inside of your eyelids). It can cause blurry vision, discomfort, and mucus production.
- Corneal ulcers: These are serious infections of the cornea that can lead to scarring, vision loss, or even blindness if left untreated. Prolonged contact lens wear drastically increases the risk of developing corneal ulcers.
- Contact lens-related infections: Bacteria, fungi, or parasites can thrive in the moist environment created by contact lenses, leading to various infections. Extended wear dramatically increases the likelihood of such infections.
- Red eyes: Consistent redness and bloodshot eyes are common signs of irritation from prolonged contact wear.
- Blurred vision: As the cornea becomes damaged or infected, vision can become blurry or distorted.
How long is too long to wear contacts?
The answer depends entirely on the type of contact lenses you wear. Disposable daily contacts have a much lower risk of complications than extended-wear contacts, even if you occasionally sleep in them. Always follow your eye doctor's instructions carefully. Never exceed the recommended wear time specified for your lenses. This is crucial information printed on the packaging.
Can wearing contacts overnight cause blindness?
While not guaranteed, wearing contacts overnight dramatically increases your risk of severe complications, including blindness. Corneal ulcers and severe infections are the primary concerns. The longer the contacts remain in your eyes beyond the recommended wear schedule, the higher the risk becomes.
What are the symptoms of wearing contacts for too long?
Symptoms can vary, but common signs of problems related to extended contact lens wear include:
- Persistent redness or bloodshot eyes
- Increased eye dryness or irritation
- Blurred vision or changes in vision
- Pain or discomfort in your eyes
- Excessive tearing or mucus discharge
- Sensitivity to light (photophobia)
- Feeling like something is in your eye
If you experience any of these symptoms, immediately remove your contact lenses and contact your eye doctor.
What should I do if I accidentally wear my contacts too long?
If you accidentally wear your contacts longer than prescribed, remove them immediately. Rinse your lenses with a solution recommended by your eye doctor. Observe your eyes carefully for any signs of irritation or infection. If you experience any symptoms, contact your eye doctor immediately. Do not try to self-treat any eye problems.
How can I prevent problems from wearing contacts too long?
The best way to prevent problems is to adhere strictly to your eye doctor's instructions on contact lens wear. Replace your lenses as directed, avoid sleeping in your contacts unless explicitly approved by your eye doctor for your specific lens type, and practice good contact lens hygiene. Regular eye exams are also crucial for early detection of any issues.
