What Happens If You Wear Contact Lenses Too Long? The Risks of Extended Wear
Wearing contact lenses for extended periods beyond their recommended wear time can lead to a range of serious eye problems. While the convenience of contacts is undeniable, understanding the potential consequences of exceeding the prescribed wear schedule is crucial for maintaining healthy eyes. This article will explore the risks associated with prolonged contact lens use and answer some frequently asked questions.
What are the risks of wearing contact lenses for too long?
The primary risk associated with wearing contacts too long is the increased likelihood of developing infections and other complications. When lenses are worn for extended periods, they accumulate debris, protein deposits, and microorganisms. This buildup can irritate the cornea (the transparent front part of your eye), leading to:
- Microbial keratitis: This is a serious infection of the cornea that can cause pain, redness, blurry vision, and even vision loss if left untreated. Bacteria, fungi, or parasites can thrive in the moist environment of the contact lens and on the eye's surface, leading to this potentially blinding infection.
- Giant papillary conjunctivitis (GPC): This condition involves the growth of large papillae (bumps) on the conjunctiva (the membrane lining the inside of the eyelids and covering the white part of the eye). GPC often leads to discomfort, redness, and blurry vision. It's frequently associated with extended wear of contact lenses, especially those with a higher water content.
- Corneal ulcer: A corneal ulcer is a deeper infection of the cornea that can result in scarring and permanent vision impairment if not treated promptly.
- Dry eye: Prolonged contact lens wear can disrupt the natural tear film, causing dryness, irritation, and discomfort. This can further increase the risk of infection.
- Hypersensitivity reactions: Some individuals may experience allergic reactions to contact lens materials or solutions, which can be exacerbated by extended wear.
- Corneal hypoxia: Contact lenses reduce the amount of oxygen reaching the cornea. While designed to minimize this, extended wear significantly increases the risk of corneal hypoxia, damaging the corneal cells.
How long is too long to wear contact lenses?
This entirely depends on the type of contact lenses you have and your eye doctor's recommendations. Always follow your eye doctor's instructions meticulously. Daily disposable lenses are designed for one-day use only. Extended-wear lenses, while allowing for overnight wear, still have a maximum wear time that should not be exceeded. Even with extended-wear lenses, your eyes need regular breaks.
Ignoring these recommendations dramatically increases the likelihood of developing complications.
What are the signs of a contact lens-related eye infection?
If you experience any of the following symptoms while wearing contact lenses, remove them immediately and consult your eye doctor:
- Increased redness and irritation
- Excessive tearing or discharge
- Blurred vision
- Pain or discomfort
- Sensitivity to light (photophobia)
- Feeling of something in your eye
Can wearing contact lenses too long cause permanent damage?
Yes, wearing contact lenses for extended periods beyond the recommended wear time can cause permanent damage to your eyes. Untreated corneal infections can lead to scarring, vision loss, and in severe cases, blindness.
What should I do if I think I have a contact lens-related infection?
Seek immediate medical attention from your eye doctor or an ophthalmologist. Do not attempt to self-treat. Early diagnosis and treatment are essential to prevent serious complications.
How can I prevent contact lens-related problems?
- Follow your eye doctor's instructions carefully: This is the most important step.
- Practice proper hygiene: Thoroughly wash and dry your hands before handling your lenses.
- Clean and disinfect your lenses according to the manufacturer's instructions: Use the appropriate cleaning solution and follow the recommended disinfection process.
- Replace your lenses as directed: Never wear lenses beyond their recommended replacement schedule.
- Schedule regular eye exams: Regular checkups allow your eye doctor to monitor your eye health and identify any potential problems early.
Remember, your eye health is paramount. Prioritize proper contact lens care and adherence to your eye doctor's recommendations to minimize the risk of complications and ensure your long-term eye health.
