What Happens If You Wear Contact Lenses Too Long? The Risks of Extended Wear
Wearing contact lenses for extended periods beyond your prescribed wearing schedule can lead to a range of serious eye problems. Ignoring recommended replacement schedules and wearing times significantly increases your risk of developing infections, corneal damage, and other sight-threatening complications. This article will explore the potential consequences of prolonged contact lens wear, answering common questions and highlighting the importance of adhering to your eye doctor's instructions.
What are the risks of wearing contacts too long?
The primary risk associated with wearing contact lenses for too long is the increased likelihood of developing an infection. Contact lenses, even when meticulously cleaned, provide a surface for bacteria and other microorganisms to grow. Prolonged wear allows these microbes more time to proliferate, increasing the chance of infection. These infections can range from mild discomfort to severe corneal ulcers, potentially leading to permanent vision impairment or even blindness.
Can wearing contacts too long cause blurry vision?
Yes, extended wear can definitely contribute to blurry vision. This can occur due to several factors:
- Dehydration: Prolonged contact lens wear can lead to dehydration of the cornea, the clear front part of your eye. This dehydration can distort vision, causing blurriness.
- Irritation and inflammation: Wearing lenses for too long can irritate and inflame the conjunctiva (the membrane lining the inside of your eyelids and covering the white part of your eye) and cornea, leading to discomfort and visual disturbances.
- Infection: As previously mentioned, infections can significantly impair vision, causing both blurriness and other visual abnormalities.
How long is too long to wear contacts?
There's no single answer to this question, as it depends entirely on the type of contact lenses you're wearing and the recommendations of your eye doctor. Always follow your eye doctor's instructions meticulously. Some lenses are designed for daily wear and should be removed at night, while others might be approved for extended wear (meaning you can leave them in for several days or even weeks). Even with extended-wear lenses, exceeding the recommended wearing time increases the risks significantly.
What are the signs of a contact lens infection?
Recognizing the signs of a contact lens infection is crucial for preventing serious complications. Seek immediate medical attention if you experience any of the following:
- Increased eye redness or irritation: More redness than usual, even after removing your lenses.
- Excessive tearing or discharge: Noticeably increased watery eyes or a thick, yellowish discharge.
- Pain or discomfort: Any significant pain or discomfort in your eye, especially when wearing the lenses.
- Blurred vision: A sudden onset of blurred vision that doesn't clear after removing your lenses.
- Sensitivity to light (photophobia): Increased sensitivity to light, making it difficult to be in brightly lit areas.
- Halos or starbursts around lights: Seeing halos or starbursts around lights, often a sign of corneal swelling or infection.
What should I do if I suspect a contact lens infection?
If you suspect a contact lens infection, immediately remove your contact lenses and contact your eye doctor or ophthalmologist. Do not attempt to self-treat. Prompt medical attention is essential to prevent potential vision loss.
Can wearing contacts too long cause permanent damage?
Yes, wearing contact lenses for excessively long periods can cause permanent damage to your eyes. Severe infections can lead to corneal scarring, which can permanently affect your vision. Even without infection, prolonged wear can contribute to corneal thinning, making it more susceptible to damage and ulcers in the future.
Conclusion:
Proper contact lens care is essential for maintaining eye health and preserving your vision. Always follow your eye doctor's instructions regarding wear time and lens replacement schedules. Never hesitate to seek professional help if you experience any discomfort or changes in your vision while wearing contact lenses. The risks of prolonged wear far outweigh any perceived convenience. Your eyesight is invaluable; protect it.
