Can I Put My Contacts in Water?

You're getting ready for bed, only to realize you've run out of contact lens solutions. In that moment of desperation, you wonder, "Can I put my contacts in water, just this once?" It seems harmless, right? After all, it's just water. 

But what if I told you that this small decision could lead to serious eye infections, discomfort, and even permanent vision damage?

You should never put your contacts in water. Water can introduce harmful bacteria and parasites, increasing the risk of eye infections and damaging your lenses.

In this post, we'll explore why putting your contacts in water is never a safe option, what happens if you do, and how to properly care for your lenses to protect your eyes.

Can You Put Contacts in Water?

You might think, "Can you leave contacts in water for a few hours while you run to the store?" It seems like a harmless shortcut, but the truth is that leaving your contacts in water, even for a short period, poses serious risks. 


Water, whether tap, distilled, or bottled, is not sterile. Unlike contact lens solution, it doesn't contain the cleaning agents necessary to kill bacteria and remove protein buildup from your lenses.

When you leave your contacts in water, bacteria and parasites can attach themselves to your contacts. These bacteria thrive in water and can cling to your contacts, leading to infections and eye irritation. Even worse, water can cause the lenses to change shape, making them uncomfortable and potentially dangerous to wear.

What Happens If You Put Contacts in Water?

The consequences are more severe than you might think. One of the biggest dangers comes from a microscopic parasite called Acanthamoeba

Found in all types of water, from tap to lake water, this parasite can cause a severe eye infection known as Acanthamoeba keratitis. The infection is painful, difficult to treat, and can sometimes lead to permanent vision loss.

According to the Centers for Disease Control and Prevention (CDC), contact lens wearers are at a higher risk of contracting Acanthamoeba keratitis if exposed to water. The CDC also reports that approximately 85% of Acanthamoeba keratitis cases occur in contact lens wearers. 

So, if you've been tempted to put your contacts in water, think again—this seemingly small decision could have long-term consequences for your eye health.

Is it Bad to Put Contacts in Water?

Absolutely. Here are some key reasons why it's bad to put contacts in water:

  1. Microbial contamination: Water contains various bacteria and microorganisms that can lead to infections. Even clean, sterile water is not safe for contact lenses.
  2. Lens damage: Water can warp and swell soft contact lenses, making them less effective and potentially harmful to your eyes.
  3. Increased risk of eye infections: As mentioned, Acanthamoeba keratitis is a serious risk. Symptoms of this infection include severe pain, redness, and blurred vision. If you experience these symptoms after exposing your lenses to water, seek medical attention immediately.
  4. Chemical reactions: Contact lenses are made from specific materials that can react negatively with water, leading to further complications.

Why Contact Lens Solution is the Only Safe Option

If you’ve ever wondered why contact lens solution is essential, here’s the key takeaway. Contact solutions are specifically formulated to clean, disinfect, and hydrate your lenses. 

They remove protein deposits that naturally build up on your lenses from your tears and kill bacteria or microorganisms that could harm your eyes.

The solution also helps maintain the shape and fit of your lenses, ensuring they stay comfortable and effective. Unlike water, which can change the shape of your lenses, the right solution keeps your contacts in the best possible condition for your eyes.

Best Practices for Contact Lens Care

To keep your eyes healthy and your lenses in good condition, follow these best practices:

  • Always use proper lens solution: Only use solutions specifically designed for contact lenses. Never substitute with water, saliva, or homemade solutions.
  • Clean your lenses regularly: Consistently follow your eye care professional’s guidelines for cleaning and disinfecting your contact lenses.
  • Avoid water activities with reusable contacts: Swimming, showering, or even splashing water on your face while wearing contacts can increase your risk of infection. If you must swim, consider wearing tight-fitting goggles.  Alternately single use contact lenses can be used while swimming and discarded immediately after.
  • Replace your lenses as directed: Stick to the replacement schedule advised by your eye care provider. Extending the use of your lenses beyond the recommended time frame can result in complications.
  • Store lenses properly: Keep your contact lenses in a clean case and use fresh storage solutions at all times. Replace your lens case every three months to reduce the risk of contamination.

Final Thoughts

Can you put contacts in water? The simple answer is no. Putting contacts in water, whether for a few hours or overnight, exposes your eyes to harmful bacteria and parasites that could lead to severe infections and long-term vision problems. 

It's always better to be cautious and use the proper lens solution to clean and store your contacts. If you find yourself without solution, you can opt for your glasses or store your lenses dry—but never use water.
