What Happens If You Wear Contacts 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 slip-up isn't likely to cause immediate disaster, consistently exceeding the prescribed wear schedule significantly increases your risk of several eye infections and complications. Understanding these risks is crucial for maintaining healthy eyes and good vision.
What are the recommended wear times for contact lenses?
This depends entirely on the type of contact lenses you use. There are daily disposables, designed to be thrown away after each use; weekly, monthly, and even longer-term disposables. Your eye doctor will prescribe the specific type and wearing schedule best suited to your eyes and lifestyle. Ignoring these recommendations is where problems arise. Each type of lens has a maximum wear time designed to minimize the risk of infection and other complications.
What are the risks of wearing contacts longer than recommended?
Ignoring the recommended wear schedule for your contact lenses increases your risk of several serious eye problems, including:
-
Microbial Keratitis: This is a serious corneal infection that can cause pain, redness, blurry vision, and even vision loss. It's often caused by bacteria, fungi, or parasites that thrive in the environment on prolonged contact lens wear. Prolonged wear provides more opportunity for these microbes to colonize your eye.
-
Giant Papillary Conjunctivitis (GPC): This condition is characterized by inflammation of the conjunctiva (the membrane lining the inside of your eyelids and covering the white part of your eye). Symptoms include itching, redness, and a gritty feeling in the eyes. While not as serious as keratitis, GPC can be very uncomfortable and can impair vision. Extended contact lens wear irritates the eye, making it more prone to GPC.
-
Corneal Ulcers: These are open sores on the cornea, and they're a particularly severe consequence of neglecting contact lens hygiene and wear schedules. They can lead to scarring and permanent vision loss.
-
Dry Eye Syndrome: Prolonged wear can deprive the cornea of essential oxygen, leading to dryness, irritation, and discomfort. This can make it harder for your tears to effectively lubricate the eye.
How long is too long? Even a few extra hours?
While a single instance of wearing your contacts a few hours longer than recommended is unlikely to cause significant problems, it's the cumulative effect of consistent over-wear that poses the greatest risk. Think of it like this: each extra hour you wear your lenses increases the chance of bacteria or other contaminants accumulating and causing infection. This risk significantly increases with prolonged and repeated over-wearing.
What are the signs that I'm wearing my contacts for too long?
Pay close attention to any changes in your vision or eye comfort. Symptoms can include:
- Redness and irritation: Persistent redness or irritation, even after removing your contacts, is a warning sign.
- Blurry vision: Changes in your vision, such as blurry or hazy vision, indicate a potential problem.
- Discomfort: Persistent discomfort, burning, itching, or a gritty feeling.
- Excessive tearing: More tears than usual can signify irritation.
- Sensitivity to light: Increased light sensitivity might be a sign of inflammation or infection.
If you experience any of these symptoms, remove your contacts immediately and consult your eye doctor.
Can I sleep in my contacts even if they’re designed for extended wear?
Even "extended-wear" contact lenses are not designed for continuous wear indefinitely. They carry a higher risk of infection than daily or short-term wear lenses, even when worn as directed. Always consult your eye doctor before considering extended-wear lenses, and strictly follow their instructions.
What should I do if I accidentally wear my contacts too long?
Remove your contacts as soon as you realize it. Wash your hands thoroughly and carefully remove the lenses. Observe your eyes closely for any signs of irritation or infection. If you experience any discomfort or notice any changes in your vision, contact your eye doctor immediately. Early intervention is crucial in preventing serious complications.
Remember, your eye health is paramount. Following your eye doctor's instructions regarding contact lens wear is vital for maintaining good vision and preventing serious complications. Don't risk your eyesight – prioritize proper care and hygiene.
