Contacts should never be exposed to water as it increases infection risks and damages lenses.
Why Water and Contact Lenses Don’t Mix
Contact lenses are delicate medical devices designed to sit on the eye’s surface, providing clear vision. They are crafted from materials that absorb moisture, which helps them stay comfortable and functional. However, water—whether tap, pool, or seawater—contains microorganisms and impurities that can cling to lenses, causing serious eye infections.
Water isn’t sterile. It harbors bacteria, fungi, and protozoa like Acanthamoeba, a microscopic organism that can cause a painful and potentially sight-threatening infection called Acanthamoeba keratitis. This infection is notoriously difficult to treat and often linked to contact lens wearers who expose their lenses to water.
Furthermore, water can alter the shape and integrity of soft contact lenses. Because these lenses absorb water, submerging them in tap or other types of water can cause swelling or warping. This distortion affects how the lens fits on the eye, leading to discomfort, blurry vision, and even micro-abrasions on the cornea.
The Risks of Using Water with Contact Lenses
Putting contact lenses in water or wearing them while swimming or showering opens the door to several serious risks:
- Eye Infections: Bacteria like Pseudomonas aeruginosa and Acanthamoeba thrive in water sources. These pathogens can attach to lenses and infect the cornea.
- Corneal Ulcers: These painful sores result from infections caused by microbes introduced through contaminated lenses.
- Lens Damage: Water exposure can cause swelling or warping of soft lenses, reducing their effectiveness and comfort.
- Irritation and Redness: Water often contains chlorine or minerals that irritate eyes when trapped under contacts.
Even small exposures—like rinsing lenses with tap water or wearing them during a shower—can increase these risks significantly.
Common Sources of Water Exposure for Contact Lens Wearers
Many people unknowingly expose their lenses to harmful water sources:
- Showering or bathing while wearing contacts lets water splash onto the eyes.
- Swimming pools, lakes, hot tubs, or oceans expose lenses to bacteria and chemicals.
- Rinsing contacts with tap water, instead of proper disinfecting solution.
- Accidental splashes from washing hands or face without removing contacts first.
Each of these scenarios increases the chance of contamination and subsequent eye problems.
The Science Behind Contact Lens Contamination by Water
Contact lenses are hydrophilic—they attract and hold water molecules. This property is great for comfort but problematic when exposed to non-sterile liquids. When immersed in tap or natural water:
- Lenses absorb microorganisms present in the liquid.
- The lens material swells unevenly due to mineral content differences.
- This swelling alters lens shape, leading to poor fit on the cornea.
- The trapped microbes multiply in the moist environment between lens and eye surface.
- The eye’s natural defenses get overwhelmed, resulting in infection symptoms like pain, redness, tearing, and blurred vision.
The microscopic gaps between lens fibers provide an ideal breeding ground for pathogens. Unlike saline solutions designed for contact care—which are sterile—water sources lack any disinfecting properties.
Acanthamoeba Keratitis: The Hidden Danger
Among all infections linked to water exposure with contacts, Acanthamoeba keratitis stands out as especially severe. This single-celled organism lives in fresh water sources worldwide. When it gains entry through contaminated contact lenses:
- The infection causes intense pain disproportionate to visible symptoms initially.
- If untreated promptly, it can lead to permanent vision loss or require corneal transplantation.
- Treatment is complex due to the organism’s resistance to many antibiotics.
Cases spike when wearers swim or rinse lenses with untreated water. Eye care professionals strongly warn against any contact between lenses and non-sterile water.
Safe Practices: Protecting Your Eyes from Water Exposure
Avoiding contact between your lenses and any type of untreated water is critical for maintaining healthy eyes. Here are essential tips:
- Never rinse or store contacts in tap or bottled water; always use sterile contact lens solutions approved by your eye care provider.
- Avoid swimming or showering with lenses on; if unavoidable, consider prescription waterproof goggles designed for swimmers.
- If you accidentally get your lenses wet: remove them immediately, disinfect thoroughly with multi-purpose solution before reinsertion—or better yet—replace them if disposable.
- Practice strict hygiene: wash hands thoroughly before handling contacts but dry them with a lint-free towel rather than letting them air dry.
Following these steps drastically reduces infection risk while preserving lens integrity.
The Role of Proper Lens Care Solutions
Contact lens care solutions are specially formulated to clean, disinfect, rinse, and store your lenses safely. Unlike plain water:
- The solutions contain antimicrobial agents that kill bacteria and fungi effectively.
- The pH balance matches that of tears for comfort during wear.
- The isotonic nature prevents swelling or shrinking of soft lenses during soaking.
Using only recommended solutions ensures your contacts remain safe for use day after day.
A Comparative Look at Water Types vs Lens Safety
| Water Type | Sterility Level | Lens Safety Impact |
|---|---|---|
| Tap Water | Non-sterile; contains bacteria & minerals | Might cause infections & lens warping; unsafe for rinsing/storing contacts |
| Bottled Water (Still) | Sterile but not disinfected for microbial safety related to eyes | Poor choice; lacks disinfectants; risk remains similar to tap water if used regularly |
| Purified/Distilled Water | Sterile but no antimicrobial agents present | Lenses may swell; no disinfection; not safe for cleaning/storing contacts alone |
| Sterile Saline Solution (Contact Care) | Sterile & isotonic; specifically formulated for contacts | Safe for rinsing & storing; maintains lens shape & kills microbes effectively |
| Swimming Pool/Sea Water/Hot Tubs | Non-sterile; high microbial load plus chemicals (chlorine/salts) | Carries high infection risk & chemical irritation; always avoid contact while wearing lenses |
The Long-Term Consequences of Ignoring “Can Contacts Go In Water?” Advice
Ignoring warnings about exposing contact lenses to any form of untreated water isn’t just a minor inconvenience—it can lead to devastating long-term consequences:
Your eyes might develop chronic irritation from repeated microbial exposure. Corneal scarring from ulcers can permanently reduce vision quality. In extreme cases where infections become resistant or severe enough, surgical intervention becomes necessary.
This isn’t just about discomfort—it’s about safeguarding one of your most vital senses: sight. The cost—in terms of pain, medical bills, lost time at work/school—is far greater than simply following proper lens care guidelines.
Lenses vs Glasses: Why Contacts Require Extra Care Around Water?
While glasses remain unaffected by moisture aside from fogging up temporarily, contacts sit directly on your eyes’ surface—making them vulnerable every time they encounter unclean liquids.
Soft contacts absorb moisture constantly—they’re like sponges soaked in whatever fluid they touch—which means they also trap contaminants inside your eye environment.
Rigid gas permeable (RGP) lenses don’t absorb as much liquid but still must avoid direct exposure since microbes stick easily onto their surfaces too.
This sensitivity makes knowing “Can Contacts Go In Water?” an essential part of responsible lens wear.
A Practical Guide: What To Do If Your Contacts Get Wet?
Accidents happen—even careful people sometimes get their contacts wet accidentally during daily activities. Here’s what you should do immediately:
- Remove your contact lenses carefully without rubbing your eyes harshly;
- If you have fresh multi-purpose solution handy, rinse each lens thoroughly;
- If unsure about contamination, discard disposable daily-wear contacts;
- If using reusable types, clean according to manufacturer instructions;
- If experiencing redness,pain,& blurry vision after exposure,seek prompt professional help;
- Avoid wearing contaminated contacts until fully treated & cleared by an eye care professional;
This quick response minimizes infection chances significantly.
