Showering with contact lenses increases infection risk and is generally not recommended for eye health.
Why Showering with Contacts Is Risky
Wearing contact lenses while showering might seem harmless, but it poses significant risks to your eyes. Water, including tap water and shower water, contains microorganisms that can cling to lenses and cause eye infections. One of the most dangerous infections linked to this habit is Acanthamoeba keratitis, a rare but severe infection that can lead to permanent vision loss.
Contact lenses act like sponges, easily absorbing water and trapping bacteria or parasites against the surface of your eye. This creates a perfect environment for microbes to thrive. Even if you use daily disposable lenses, exposing them to water during a shower can introduce harmful pathogens that your eye’s natural defenses may struggle to fight off.
Moreover, water exposure can cause lenses to swell or change shape. This distorts vision and may cause discomfort or even small abrasions on the cornea, increasing the risk of infection further.
How Water Affects Contact Lenses
Water isn’t sterile. It contains bacteria, amoebas, and other microorganisms invisible to the naked eye. When you shower with contacts in, these organisms can attach themselves to the lens surface or get trapped between your lens and cornea.
Here’s what happens when water interacts with contact lenses:
- Lens Contamination: Microbes from water stick to the lens surface.
- Lens Swelling: Water absorption causes lenses to swell and lose their proper fit.
- Reduced Oxygen Permeability: Swollen lenses reduce oxygen flow to your cornea.
- Corneal Abrasions: Swollen or misshaped lenses can scratch your eye’s surface.
All these factors increase discomfort and heighten the chances of developing infections. The cornea needs oxygen to stay healthy; anything blocking oxygen flow weakens its defenses.
Types of Microorganisms in Shower Water
Shower water often comes from municipal supplies but isn’t sterile by any means. It might contain:
- Acanthamoeba: A microscopic amoeba found in tap water; causes severe keratitis.
- Pseudomonas aeruginosa: A common bacterium linked with eye infections.
- Fusarium: A fungal organism that can infect eyes, especially when contacts are exposed to contaminated water.
These pathogens are usually harmless without contact lenses because your tears wash them away. But lenses trap them against your eye’s surface for prolonged periods.
The Science Behind Eye Infections From Water Exposure
Acanthamoeba keratitis is one of the most serious infections linked directly to showering with contacts. This parasite attaches itself tightly to the cornea and feeds on cells, causing painful inflammation and scarring.
Unlike bacterial infections that respond well to antibiotics, Acanthamoeba infections are tough to treat. They often require months of intensive therapy, sometimes leading to corneal transplants or permanent vision loss.
Other common infections include bacterial keratitis caused by Pseudomonas aeruginosa and fungal keratitis from Fusarium species. Both result in redness, pain, blurred vision, tearing, and light sensitivity.
Wearing contacts in the shower increases exposure time since microbes have more opportunity to colonize under wet lenses compared to dry eyes exposed briefly during swimming or washing hands.
What Experts Say About Showering With Contacts
Eye care professionals strongly advise against wearing contacts while showering. The American Optometric Association (AOA) warns that “exposure of contact lenses to any type of non-sterile water increases risk of serious eye infection.”
Similarly, the Centers for Disease Control and Prevention (CDC) highlight that “contact lens wearers should avoid exposing their lenses to any form of water—including tap water—because it can harbor germs that cause serious infections.”
Even if you think your skin feels fine after showering with contacts on, microscopic damage might already be occurring beneath the lens surface.
Practical Recommendations From Eye Care Providers
- Avoid Wearing Contacts in Water: Remove lenses before swimming or showering.
- Use Daily Disposables: If accidental exposure happens, discard those lenses immediately instead of reusing them.
- Maintain Proper Hygiene: Always wash hands before handling contacts.
- Use Sterile Solutions Only: Never rinse or store lenses in tap water.
These simple steps reduce infection risks dramatically while preserving good eye health.
The Effects of Shower Temperature on Contact Lens Safety
Hot showers might feel relaxing but they also increase risks when wearing contacts. Warm water encourages microbial growth more than cold water does. Plus, hot steam causes sweating which could lead you to rub your eyes unconsciously — another way germs hitch a ride onto your lenses.
Cold showers don’t eliminate risks either since microbes survive across temperature ranges typical in household plumbing systems.
So regardless of temperature settings, showering with contacts remains unsafe due to contamination potential alone.
Lenses Material Sensitivity To Water Exposure
Not all contact lens materials react identically when exposed to water:
| Lens Material Type | Sensitivity To Water | Description |
|---|---|---|
| Softer Hydrogel Lenses | High | Tend to absorb more water causing swelling and distortion quickly. |
| Silikon Hydrogel Lenses | Moderate | Slightly less absorbent but still vulnerable to microbial contamination from water exposure. |
| Rigid Gas Permeable (RGP) Lenses | Low | Dense material resists swelling but still traps bacteria if exposed during showering. |
Even though RGPs resist swelling better than soft types, none are safe for use during showers due to contamination risks.

Frequently Asked Questions
Can You Take a Shower With Contacts Without Risk?
Showering with contact lenses is generally not recommended due to the increased risk of eye infections. Water contains microorganisms that can cling to lenses, potentially causing serious infections like Acanthamoeba keratitis. Avoiding water exposure helps protect your eye health.
Why Is It Dangerous to Shower With Contacts In?
Water can cause contact lenses to swell and change shape, leading to discomfort and corneal abrasions. These changes reduce oxygen flow to the cornea and create an environment where harmful microbes can thrive, increasing the risk of infection.
What Types of Infections Can Result From Showering With Contacts?
Showering with contacts exposes your eyes to bacteria, fungi, and amoebas such as Acanthamoeba keratitis, Pseudomonas aeruginosa, and Fusarium. These microorganisms can cause severe infections that may result in vision loss if not treated promptly.
Are Daily Disposable Contacts Safe to Wear in the Shower?
Even daily disposable lenses are not safe to wear while showering. Water exposure can introduce pathogens that your eyes may struggle to fight off, regardless of lens type. It’s best to remove contacts before showering for optimal eye safety.
How Can You Protect Your Eyes If You Accidentally Shower With Contacts?
If you accidentally shower with contacts in, remove them as soon as possible and disinfect them properly if they are reusable. Monitor for any redness, pain, or vision changes and consult an eye care professional immediately if symptoms develop.
The Impact on Vision Quality After Shower Exposure
Water exposure impacts not only safety but also how well you see through your contacts afterward:
- Lenses may become foggy or cloudy after absorbing minerals from hard tap water.
- Lenses lose their proper shape causing blurred or distorted vision temporarily or permanently if damage occurs.
- Irritation from chemical residues like chlorine (in some municipal supplies) worsens discomfort after showers.
- Dried deposits from soap or shampoo trapped under lenses create gritty sensations making blinking painful.
- Avoid rubbing your eyes immediately;
- Remove the lenses promptly;
- If disposable daily lenses were used—discard them;
- If reusable lenses—clean thoroughly using multipurpose disinfectant solutions;
- Avoid using tap water for rinsing;
- If irritation persists—consult an eye care professional immediately.
These problems affect daily activities like reading or driving until you replace or properly clean your lenses again — assuming they’re salvageable at all after an accidental shower encounter.
The Role Of Proper Lens Care Post-Shower Exposure
If you accidentally showered with contacts in place:
This routine minimizes potential damage but doesn’t eliminate all risks linked with initial exposure.
The Bottom Line – Can You Take a Shower With Contacts?
The short answer is no—it’s best not to take a shower with contact lenses on. The dangers outweigh any convenience gained by leaving them in during washing up. Eye infections caused by contaminated water trapped under contacts are serious threats capable of long-term damage.
Protecting your vision means avoiding unnecessary risks like showering with contacts. Removing them beforehand keeps harmful microbes away while preventing lens swelling and discomfort caused by moisture exposure.
