What Happens If You Wear Contact Lenses Too Long? The Risks of Extended Wear
Wearing contact lenses beyond their recommended wear time can lead to a range of serious eye problems. While the occasional slight over-wear might not cause immediate harm, consistently exceeding the prescribed wear schedule significantly increases your risk of developing several eye conditions. This article delves into the potential consequences of extended contact lens wear and offers guidance on maintaining healthy eye habits.
What are the recommended wearing times for contact lenses?
The recommended wearing time for contact lenses varies depending on the type of lenses you have. Daily disposables, as the name suggests, should be discarded after a single day of use. Extended-wear lenses, while designed for overnight wear, still have usage limits. Always follow the specific instructions provided by your eye doctor and the lens manufacturer. Never exceed the recommended wear time, even if your eyes feel comfortable.
What are the risks of wearing contact lenses too long?
Prolonged contact lens wear dramatically increases your risk of several eye problems, including:
-
Corneal Ulcers: These are open sores on the cornea (the clear front part of your eye). They can cause significant pain, blurry vision, and even vision loss if left untreated. Extended wear deprives the cornea of sufficient oxygen, making it more susceptible to infection.
-
Corneal Infiltrates: These are small, cloudy spots on the cornea that are often caused by inflammation or infection. They can affect your vision and, if severe, require treatment.
-
Giant Papillary Conjunctivitis (GPC): This condition causes inflammation of the conjunctiva (the membrane lining the eyelid and covering the white part of your eye). It leads to itchy, watery eyes and can be uncomfortable. It's often linked to extended wear and inadequate lens hygiene.
-
Contact Lens-Associated Dry Eye Disease: Prolonged contact lens use can lead to dry eye symptoms like burning, stinging, itching, and blurry vision. This is because the lenses can interfere with the natural tear film, causing dryness and irritation.
-
Infection: Wearing contact lenses for extended periods increases the risk of bacterial, fungal, or parasitic infections. These can range from mild to severe and can cause significant vision impairment.
What are the symptoms of problems caused by wearing contact lenses too long?
The symptoms of complications from prolonged contact lens wear can be subtle at first, but should not be ignored. Be vigilant for:
- Redness or irritation: More than usual redness, itching, or burning in your eyes.
- Blurred or decreased vision: Difficulty seeing clearly, even with your contact lenses in.
- Excessive tearing or dryness: Unusual amounts of tearing or a feeling of dryness and discomfort.
- Pain or sensitivity to light (photophobia): Sharp pain or discomfort when exposed to light.
- Pus or discharge from the eyes: Yellowish or greenish discharge, indicating a possible infection.
If you experience any of these symptoms, remove your contact lenses immediately, and contact your eye doctor. Do not attempt to self-treat.
How can I prevent problems from wearing contact lenses too long?
The best way to prevent complications is to strictly adhere to the recommended wear schedule for your contact lenses. Remember to:
- Follow your eye doctor's instructions precisely: This includes wearing time, cleaning procedures, and replacement schedules.
- Practice meticulous hygiene: Thoroughly clean and disinfect your lenses as directed.
- Remove your lenses before sleeping (unless specifically instructed otherwise): This allows your eyes to receive adequate oxygen overnight.
- Attend regular eye exams: Routine check-ups allow your eye doctor to monitor the health of your eyes and detect any potential problems early.
Wearing contact lenses is a privilege that requires responsibility. Always prioritize eye health by following your eye doctor's recommendations and practicing good hygiene. If you have any questions or concerns, don't hesitate to consult your eye care professional. Ignoring symptoms or exceeding the recommended wear time can have severe consequences for your vision.
