In the world of contact lens care, there are many “do’s” and “don’ts,” but few are as crucial and non-negotiable as this: Never let tap water come into contact with your contact lenses or lens case.
While it might seem harmless, or even clean, the distinction between tap water and contact lens solution is a matter of eye safety.
The Hidden Danger in Tap Water: Acanthamoeba Keratitis
The primary and most severe risk associated with tap water is a microscopic organism called Acanthamoeba. This amoeba is commonly found in soil, lakes, rivers, and yes, even in treated tap water, showers, and swimming pools.
If Acanthamoeba comes into contact with your contact lenses, it can get trapped between the lens and your eye. It then has the opportunity to infect the cornea (the clear front surface of your eye), leading to a devastating condition called Acanthamoeba Keratitis (AK).
- What is AK? It’s a rare but extremely painful and sight-threatening eye infection that can cause severe vision loss or even require a corneal transplant. It’s notoriously difficult to treat and requires prolonged, aggressive medical intervention.
- Why is it so dangerous for lens wearers? The contact lens acts like a microscopic “splinter” that helps the amoeba attach to the cornea, especially if there’s any tiny scratch or abrasion on the eye’s surface.
Why Contact Lens Solutions Are Different
Contact lens solutions (saline, multipurpose, or hydrogen peroxide systems) are specifically formulated and sterilized for safe contact with your eyes and lenses.
- Sterility: They are free of harmful microorganisms, including Acanthamoeba.
- pH Balance: They are balanced to match the natural pH of your tears, preventing irritation.
- Disinfecting Agents: Multipurpose and hydrogen peroxide solutions contain active ingredients designed to kill bacteria, fungi, and other microbes that can contaminate your lenses. Tap water has none of these properties.
Common Mistakes to Avoid at All Costs
- Rinsing Lenses with Tap Water: Even a quick rinse can introduce dangerous microbes.
- Storing Lenses in Tap Water: This provides a perfect breeding ground for bacteria and amoebae.
- Washing Your Lens Case with Tap Water: Always use sterile contact lens solution, rub it, rinse it, and let it air dry.
- Showering or Swimming with Lenses In: This exposes your lenses directly to water sources.
