What Happens If You Wear Contacts Too Long? The Risks of Extended Contact Lens Wear
Wearing contact lenses offers convenience and clear vision, but exceeding the recommended wear time carries significant risks to your eye health. Ignoring proper care and replacement schedules can lead to a range of problems, from minor discomfort to serious infections that could permanently impair your vision. This article explores the potential consequences of prolonged contact lens use, answering common questions about this crucial aspect of eye care.
What are the risks of wearing contacts too long?
The risks associated with wearing contacts for extended periods or beyond their recommended replacement schedule are numerous and serious. These include:
- Corneal Ulcers: These are open sores on the cornea (the clear front part of your eye) and are a major risk of prolonged contact lens wear. Ulcers can cause severe pain, blurred vision, light sensitivity, and even vision loss if left untreated. Bacteria thrive in the moist environment of the eye, especially when a contact lens acts as a breeding ground.
- Conjunctivitis (Pink Eye): This common infection of the conjunctiva (the membrane covering the white part of the eye) can be caused by bacteria or viruses. Extended contact lens wear increases the risk of developing pink eye, due to the irritation and foreign body in the eye.
- Giant Papillary Conjunctivitis (GPC): This is a reaction to contact lenses, characterized by the growth of large papillae (bumps) on the conjunctiva. GPC can cause significant discomfort, redness, and blurry vision.
- Contact Lens-Related Dry Eye: Prolonged contact lens wear can disrupt the tear film, leading to dry, irritated eyes. This dryness can cause discomfort, blurry vision, and increased susceptibility to infections.
- Corneal Infiltrates: These are small, cloudy areas on the cornea that can be caused by irritation, infection, or inflammation. They can affect vision and may require treatment.
- Infections: A variety of infections, including bacterial keratitis (inflammation of the cornea), can result from wearing contacts for too long. These infections can be severe and may require antibiotic treatment or even surgery.
How long is too long to wear contacts?
The answer to this question depends on the type of contact lenses you wear. Always follow your eye doctor's instructions regarding wear time and replacement schedules. There's no one-size-fits-all answer.
- Daily disposable contacts: These are designed to be worn for one day only and then discarded. Wearing them for longer increases the risk of infection.
- Extended-wear contacts: Even these lenses, specifically designed for overnight wear, have limitations. Continuously wearing them for extended periods without removing them for cleaning can increase risk. Always consult your optometrist about your specific lens type and recommended wear schedule.
- Other types of contact lenses: Whether monthly, bi-weekly, or other replacement schedules, exceeding the recommended wear time increases the risk of infection and eye problems.
What are the symptoms of wearing contacts for too long?
If you suspect you've worn your contacts for too long, watch for these symptoms:
- Redness and irritation: This is a common early warning sign.
- Blurred vision: This could indicate a corneal ulcer or other infection.
- Pain and discomfort: Any significant eye pain requires immediate attention.
- Excessive tearing or dryness: These indicate problems with your tear film, possibly due to contact lens irritation.
- Sensitivity to light: This can be a sign of corneal damage or infection.
- Feeling like something is in your eye: This is a common symptom of irritation or infection.
What should I do if I think I've worn my contacts too long?
If you experience any of the above symptoms, immediately remove your contact lenses and contact your eye doctor. Do not attempt to self-treat. Early detection and treatment of eye infections are crucial to prevent permanent vision damage.
How can I prevent problems from wearing contacts too long?
- Follow your eye doctor's instructions precisely: This is the most important step.
- Properly clean and disinfect your lenses: Thoroughly clean your lenses every day, using the cleaning solution recommended by your doctor.
- Replace your lenses according to the recommended schedule: Never wear contacts beyond their recommended replacement time.
- Practice good hand hygiene: Wash your hands thoroughly before handling your contact lenses.
- Remove lenses immediately if you feel any discomfort: Don't wait for symptoms to worsen.
- Schedule regular eye exams: Your eye doctor can monitor the health of your eyes and ensure your lenses are fitting properly.
By diligently following these guidelines, you can significantly reduce the risk of problems associated with wearing contact lenses. Remember, your eye health is paramount. Prioritize proper care and regular check-ups with your eye doctor.
