Is It Safe to Rinse Your Eyes With Tap Water?

Why Tap Water and Eyes Don’t Mix

Many people assume that because tap water is treated, it’s safe for any use. But when it comes to your eyes, even clean-looking tap water can introduce harmful microorganisms that increase your risk for infection.

Your eyes are highly sensitive organs. The cornea—the clear outer layer of the eye—can easily become irritated or infected by microscopic contaminants in water. These include bacteria, fungi, and acanthamoeba, an organism known to cause a serious condition called acanthamoeba keratitis.

What Is Acanthamoeba Keratitis?

Acanthamoeba keratitis is a rare but painful and potentially sight-threatening infection of the cornea. While rare, it can be difficult to treat, and in some cases, it may lead to permanent vision loss. The risk increases if you wear contact lenses and use tap water for rinsing, storing, or cleaning them.

Why the Risk Is Greater for Contact Lens Wearers

If you wear contact lenses, you’re more vulnerable to water-related infections. That’s because:

Lenses can trap contaminants against your eye
Contact lens cases are prone to bacterial buildup when cleaned with tap water
Moist environments, like lens cases, are ideal for microorganism growth

In fact, rinsing your lenses or your eyes with tap water—even once—can create conditions for an infection to develop.

Safe Lens Care Tips

Never use tap water to rinse or store contact lenses
Use only recommended disinfecting solutions from your eye doctor
Always wash your hands before handling your lenses
Replace lens cases every 1–3 months

If your eyes feel dry, itchy, or irritated while wearing lenses, don’t try rinsing them with water. Remove them and consult your optometrist instead.

What To Do If You Get Something in Your Eye

Whether it’s dust, makeup, or a stray eyelash, it’s tempting to splash some water and hope for the best. But again, water isn’t your safest option.

Try These Steps Instead:

Blink repeatedly to help flush out the irritant naturally
Use sterile saline or artificial tears to rinse the eye
Avoid rubbing, which can scratch the surface of the eye
See your optometrist if irritation, redness, or discomfort persists

When to Seek Help From an Eye Doctor

If you’ve used tap water to rinse your eyes or contact lenses and now experience symptoms such as:

Redness or irritation
Blurry vision
Sensitivity to light
A gritty feeling or eye pain

Schedule an eye exam right away. Early treatment can prevent long-term damage and protect your vision.
