Cleaning contact lenses with water is unsafe and can cause serious eye infections and damage.
Why Water Is Not Safe for Cleaning Contact Lenses
Contact lenses are delicate medical devices designed to sit directly on the eye’s surface. Despite their small size, they require precise care to maintain eye health. Using water to clean or rinse contacts might seem harmless, but it poses significant risks. Tap water contains microorganisms, minerals, and impurities that can cling to the lens surface. These contaminants can lead to infections such as Acanthamoeba keratitis—a rare but severe eye infection that can cause vision loss.
Unlike sterile saline or multipurpose contact lens solutions formulated specifically for lens care, water lacks disinfecting properties. It cannot remove proteins, lipids, or bacteria effectively from the lens surface. This means that rinsing contacts with water leaves behind residues and harmful microbes that increase the risk of irritation and infection.
Even distilled or bottled water is not recommended because it is not sterile and may harbor microorganisms. The safest approach is always to use solutions approved by eye care professionals designed explicitly for contact lens hygiene.
The Science Behind Contact Lens Contamination
Contact lenses attract deposits from tears and the environment during wear. These deposits include proteins, lipids, dust particles, and microbes. Proper cleaning removes these substances and disinfects the lenses before insertion.
Water does not disinfect; instead, it can introduce new pathogens. For instance:
- Acanthamoeba: A microscopic amoeba found in tap water that can cause painful corneal infections when introduced via lenses.
- Bacterial contamination: Waterborne bacteria like Pseudomonas aeruginosa thrive in moist environments and can adhere to lenses.
- Fungal spores: These can also be present in non-sterile water sources.
The cornea is one of the most sensitive tissues in the body, lacking blood vessels and relying on tears for nutrients and defense. Introducing pathogens through contaminated lenses compromises this defense system.
Proper Methods to Clean Contact Lenses
Safe contact lens cleaning involves several critical steps:
1. Use Approved Contact Lens Solutions
Multipurpose solutions are designed to clean, rinse, disinfect, and store lenses safely. Some users may prefer hydrogen peroxide-based systems that require neutralization before insertion.
2. Follow the Rub-and-Rinse Technique
Even if a solution claims “no rub” on its label, gently rubbing each side of the lens with fingertips removes stubborn deposits more effectively than rinsing alone.
3. Store Lenses in a Clean Case
Lens cases should be cleaned daily with fresh solution (never water), dried thoroughly, and replaced every three months or sooner if damaged or contaminated.
4. Avoid Using Saliva or Tap Water
Saliva contains bacteria harmful to eyes. Tap water has microorganisms and minerals unsuitable for lens care.
The Risks of Using Water: Real-World Consequences
Eye doctors frequently warn against using water due to documented cases of severe infections linked to improper lens hygiene practices involving tap or other non-sterile waters.
Acanthamoeba keratitis is particularly notorious because it’s difficult to treat and often requires prolonged medical intervention including antifungal medications or even corneal transplants in extreme cases.
Besides infections, using water can cause:
- Lens damage: Minerals in hard water may alter lens shape or cloud them.
- Eye irritation: Residual impurities cause redness, burning sensations, or dryness.
- Reduced comfort: Deposits left after rinsing with water decrease comfort during wear.
These complications increase discomfort and threaten long-term vision health.
The Differences Between Water Types Used Around Contacts
Not all waters are created equal regarding safety around contact lenses:
| Water Type | Sterility Level | Risk When Used With Contacts |
|---|---|---|
| Tap Water | Non-sterile; contains microbes & minerals | High risk of infection; not recommended for any contact use |
| Bottled/Distilled Water | Semi-purified but not sterile; may harbor microbes | Still risky; lacks disinfectant properties; avoid use on contacts |
| Sterile Saline Solution (Contact Lens Grade) | Sterile; formulated for safe rinsing/storage | Safe for rinsing but does not disinfect alone; use with cleaning step |
| Multipurpose Contact Lens Solution | Sterile; cleanses & disinfects lenses simultaneously | Recommended standard for cleaning & storing contacts safely |
This table clearly shows why only specific solutions approved for contact care should be used instead of any form of plain water.
