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 serious eye problems. While the convenience of contacts is undeniable, understanding the risks associated with extended wear is crucial for maintaining healthy eyes. This article will explore the potential consequences and answer common questions surrounding this important topic.
What are the recommended wearing times for contact lenses?
The recommended wearing time for contact lenses varies significantly depending on the type of lens. Daily disposable lenses, as the name suggests, are designed to be discarded after a single day's use. Extended-wear lenses, on the other hand, may be worn overnight, but even these have limits and should be replaced according to your eye doctor's instructions. Never exceed the recommended wear time specified by your eye care professional and the lens manufacturer.
What are the risks of exceeding the recommended wearing time?
Exceeding the recommended wear time, regardless of the type of lens, dramatically increases your risk of various eye infections and complications. These include:
-
Microbial Keratitis: This is a serious infection of the cornea, the clear front part of your eye. It can cause pain, redness, blurry vision, and even vision loss if left untreated. Prolonged contact lens wear creates a breeding ground for bacteria and other microorganisms.
-
Giant Papillary Conjunctivitis (GPC): This is an allergic reaction that causes the growth of large papillae (bumps) on the conjunctiva, the membrane lining the inside of your eyelids. It leads to discomfort, redness, and blurry vision. This condition is often associated with extended wear of contact lenses.
-
Corneal Ulcers: These are open sores on the cornea and are a severe complication of contact lens-related infections. They can cause significant pain, vision impairment, and even lead to permanent vision loss.
-
Hypoxia: The cornea needs oxygen to stay healthy. Contact lenses can reduce the amount of oxygen reaching the cornea. Prolonged wear exacerbates this, leading to discomfort and potentially more severe complications.
-
Dry Eye Syndrome: Extended contact lens use can worsen symptoms of dry eye, leading to increased irritation and discomfort.
Can wearing contacts too long cause blindness?
While not a guaranteed outcome, in severe cases of untreated corneal infections caused by extended contact lens wear, blindness is a potential, albeit serious, complication. Prompt medical attention is essential to mitigate this risk.
What are the signs of a contact lens-related eye infection?
If you experience any of the following symptoms, immediately remove your contact lenses and consult your eye doctor:
- Increased redness or irritation
- Excessive tearing or discharge
- Blurred vision
- Eye pain or discomfort
- Sensitivity to light (photophobia)
- Feeling of something in your eye
How can I prevent complications from wearing contacts too long?
The best way to prevent complications is to:
- Follow your eye doctor's instructions precisely. This includes adhering to the recommended wearing time and replacement schedule.
- Practice good hygiene. Thoroughly wash and dry your hands before handling contact lenses. Clean and disinfect your lenses as instructed.
- Attend regular eye exams. Your eye doctor can monitor your eye health and detect any potential problems early.
- Remove your contacts immediately if you experience any discomfort.
In Conclusion:
While contact lenses offer a convenient vision correction option, exceeding the recommended wearing time significantly increases the risk of serious eye problems. Prioritizing proper lens hygiene, adhering to your eye doctor's instructions, and seeking immediate medical attention at the first sign of any problem are crucial for maintaining healthy eyes and preserving your vision. Remember, your eye health is paramount.
