If you've ever been caught without contact lens solution and thought about using water as a substitute, you're not alone. But while it might seem harmless, using water on contact lenses—even in an emergency—is actually a risky idea. Let's explore why water and contact lenses don't mix and what safer alternatives you can use instead.
Why Water is Unsafe for Contact Lenses
Water, whether tap, bottled, or distilled, is not sterile. It can contain harmful microorganisms, including Acanthamoeba, a tiny parasite that can cause severe eye infections like Acanthamoeba keratitis. Even a small splash of tap water can introduce bacteria or fungi to your lenses, increasing the risk of eye infections that could potentially damage your vision.Additionally, water can cause your contact lenses to lose their shape and stick to your eye, making them uncomfortable and difficult to remove. This can lead to irritation, dryness, and even corneal abrasions.
The Risks of Using Water
Infections: Water can harbor bacteria and parasites that are dangerous for the eyes.
Lens Damage: Water can alter the lens shape, making it difficult to wear or remove.
Eye Irritation: Water lacks the proper pH balance and lubricants found in contact lens solutions, leading to dryness and discomfort.
What to Do in an Emergency
If you find yourself without contact lens solution, the safest option is to remove your lenses and store them in a clean, dry case until you can access proper solution. Never use water or homemade saline solutions, as these can cause more harm than good. If you’re traveling, consider carrying single-use, travel-size bottles of contact lens solution to avoid this issue altogether.
Safe Alternatives to Water
If your lenses feel dry or uncomfortable and you don’t have your usual solution, use sterile saline solution or rewetting drops specifically made for contact lenses. These products are designed to be safe and effective for use with contacts and won’t introduce harmful microbes to your lenses.
