For many of us, contact lenses are a convenient and effective way to improve vision without the hassle of glasses. However, wearing contact lenses while showering can lead to serious and often underestimated health risks. If you’re someone who frequently keeps their lenses in during a shower, it’s time to reconsider this seemingly harmless habit. Below, we delve into the hidden dangers of showering with contact lenses and provide actionable advice to protect your eye health.
Why Showering with Contact Lenses Is Risky
Showering with contact lenses exposes your eyes to a variety of potential dangers. The primary risks stem from the contact lenses’ interaction with water and the contaminants it carries.
1. Contaminated Water and Eye Infections
Tap water, while generally safe to drink, is not sterile. It can contain microorganisms such as Acanthamoeba, a tiny organism that can cause a severe eye infection known as Acanthamoeba keratitis. This condition leads to painful symptoms, including redness, blurred vision, and even permanent damage to the cornea, potentially resulting in vision loss.
When you wear contact lenses in the shower, water can become trapped between the lens and your eye, creating a perfect environment for these microorganisms to grow and thrive.
2. Increased Risk of Corneal Damage
Water exposure can cause your contact lenses to warp or stick to your cornea. This can result in mechanical irritation, which increases the likelihood of scratches or abrasions on the corneal surface. Damaged corneal tissue is more vulnerable to infection, making even minor irritations a potential entry point for harmful bacteria.
3. Biofilm Formation on Contact Lenses
Water exposure can lead to the formation of a biofilm—a thin, slimy layer of bacteria and other microbes—on your contact lenses. Once formed, biofilms are extremely difficult to remove and can further exacerbate the risk of infections, even if you clean your lenses thoroughly afterward.
Key Symptoms of Water-Related Eye Issues
If you frequently shower with contact lenses, it’s crucial to watch for symptoms that could indicate a developing problem. Common warning signs include:
- Persistent eye redness or irritation
- Blurred or reduced vision
- A feeling of grit or a foreign object in the eye
- Sensitivity to light
- Excessive tearing or discharge
If you experience any of these symptoms, seek immediate medical attention. Delayed treatment can lead to more severe complications.
What Science Says About Water and Contact Lenses
Numerous studies have highlighted the connection between water exposure and contact lens-related infections. For instance, research published in the American Journal of Ophthalmology has shown that individuals who expose their contact lenses to water are significantly more likely to develop serious infections, including Acanthamoeba keratitis. Experts unanimously recommend avoiding water contact entirely when wearing contact lenses.
Additionally, global organizations like the Centers for Disease Control and Prevention (CDC) and the American Academy of Ophthalmology (AAO) advise against exposing contact lenses to water—whether it’s tap water, pool water, or even distilled water.
Best Practices for Contact Lens Wearers
To safeguard your eye health, follow these essential guidelines:
1. Remove Lenses Before Showering
The simplest and most effective way to avoid water-related risks is to remove your contact lenses before stepping into the shower. Always store them in a sterile lens case filled with the appropriate contact lens solution.
2. Use Daily Disposable Lenses
If removing lenses before every shower seems inconvenient, consider switching to daily disposable lenses. These lenses are discarded at the end of each day, reducing the risk of contamination.
3. Avoid Reusing Contact Lens Solution
Never top off or reuse old lens solution. Always use fresh solution for cleaning and storing your lenses to minimize the risk of bacterial growth.
4. Adhere to Proper Lens Care
Ensure you clean and disinfect your lenses as per the manufacturer’s instructions. Replace your lenses and lens case regularly to prevent the buildup of harmful microbes.
5. Schedule Regular Eye Exams
Visit your optometrist regularly to monitor your eye health. Early detection of any issues can prevent complications and ensure your vision stays sharp.
Special Considerations for Pool and Hot Tub Use
Showering isn’t the only scenario where water and contact lenses can be a dangerous combination. Activities like swimming in pools, hot tubs, or natural water bodies pose similar risks. Chlorine in pools can irritate your eyes, and untreated water in lakes or oceans can carry harmful microorganisms. Always wear swimming goggles if you plan to swim with your lenses in, or remove them beforehand.
The Importance of Educating Contact Lens Users
Many contact lens wearers are unaware of the risks associated with water exposure. Increasing awareness through proper education is crucial to reducing preventable infections and complications. Eye care professionals and optometrists play a vital role in spreading this information during routine check-ups.
Conclusion: Protect Your Vision by Breaking the Habit
While showering with contact lenses may seem harmless, the potential risks are significant and should not be overlooked. By understanding the dangers and adopting healthier habits, you can protect your eyes from infections and long-term complications. Always prioritize your eye health by avoiding water contact with your lenses, following proper care routines, and consulting an eye care professional if you have concerns.
