What Happens If You Wear Contact Lenses Too Long? The Risks of Extended Wear
Wearing contact lenses beyond their recommended wear time, whether daily, extended wear, or even just a few extra hours, can lead to a range of serious eye problems. Understanding these risks is crucial for maintaining healthy eyes and good vision. This article will explore the potential consequences of prolonged contact lens use, answering common questions about this important topic.
What are the risks of wearing contacts too long?
Prolonged contact lens wear increases your risk of several eye infections and complications. The most common issues stem from a buildup of bacteria, debris, and protein deposits on the lens surface. These deposits irritate the cornea (the clear front part of your eye), leading to discomfort and potential vision problems. The longer you wear your lenses beyond the recommended time, the greater the risk of these issues escalating.
Specifically, extended wear can increase your chances of:
-
Microbial Keratitis: This is a serious infection of the cornea, often caused by bacteria, fungi, or parasites. Symptoms can range from mild discomfort to severe pain, blurred vision, and even vision loss if left untreated. This is a significant concern with extended wear, as the longer the lenses stay in, the more opportunity there is for microorganisms to grow.
-
Giant Papillary Conjunctivitis (GPC): This condition causes the formation of large bumps (papillae) on the conjunctiva (the membrane lining the inside of your eyelids). GPC often results in discomfort, redness, and blurry vision, and it's more common with extended wear or improper lens hygiene.
-
Corneal Ulcers: These are open sores on the cornea. They are often a consequence of untreated infections and can lead to permanent vision impairment or even blindness if not addressed promptly.
-
Dry Eye: Even without infection, prolonged contact lens wear can lead to dry eye syndrome due to reduced tear production and increased evaporation. This can result in burning, itching, and blurry vision.
-
Hypersensitivity: Extended wear can sometimes trigger an allergic reaction or hypersensitivity response in some individuals, further exacerbating discomfort and eye irritation.
How long is too long to wear contact lenses?
The answer to this question varies depending on the type of contact lenses you are wearing. Always follow the recommendations of your eye doctor and the manufacturer's instructions. Daily disposable lenses are designed for single-day use, while extended wear lenses have specific guidelines, often allowing for overnight wear, but still with limitations. Even with extended wear lenses, exceeding the recommended wear time substantially increases your risk of complications. There's no magic number; exceeding the recommendation is inherently risky.
What should I do if I accidentally wear my contacts too long?
If you accidentally exceed the recommended wear time for your contact lenses, remove them immediately and thoroughly clean them if reusable. If you experience any discomfort, redness, blurred vision, or excessive tearing, consult your eye doctor as soon as possible. Early intervention is key in preventing serious complications.
Can wearing contacts too long cause blindness?
While not a guaranteed outcome, wearing contacts for excessively long periods significantly increases your risk of developing serious eye infections like microbial keratitis, which can lead to blindness if left untreated. Therefore, it's crucial to follow your eye doctor's instructions and prioritize proper lens hygiene to minimize this risk.
What are the signs of a contact lens-related eye infection?
Signs of a contact lens-related eye infection can include:
- Increased redness or bloodshot eyes
- Significant pain or discomfort
- Excessive tearing
- Blurred vision
- Sensitivity to light (photophobia)
- Feeling of something in your eye
- Pus or discharge from the eye
If you experience any of these symptoms, remove your contact lenses immediately and consult your eye doctor immediately.
By diligently following your eye doctor's recommendations and maintaining meticulous contact lens hygiene, you can significantly reduce the risk of complications associated with wearing your contacts. Remember, your eye health is paramount; prioritize proper care and seek professional help if you experience any concerns.
