No, you should never clean your contact lenses with water.
Tap water, bottled water, and even distilled water can contain microorganisms, such as Acanthamoeba, bacteria, and other pathogens that can adhere to your contact lenses. These microorganisms can cause serious eye infections, including Acanthamoeba keratitis, a painful and potentially blinding infection.
Here's why water is unsafe for cleaning contacts:
- Microorganisms: Water is not sterile and can harbor harmful microorganisms that can thrive on contact lenses.
- Contact Lens Material: Contact lenses are designed to be cleaned and stored in specific solutions that maintain their hydration and prevent damage. Water can alter the shape and fit of the lens.
- Eye Health Risks: Using water can lead to severe eye infections, corneal ulcers, and even permanent vision loss.
What to do if you run out of contact lens solution:
- Use a Backup Solution: Always keep a spare bottle of contact lens solution on hand.
- Remove and Discard: If you don't have solution, it's safer to remove your lenses and discard them.
- Consult an Eye Doctor: If you experience any eye irritation or discomfort, contact your eye doctor immediately.
Safe Alternatives:
- Multi-Purpose Solution: Use a multi-purpose solution specifically designed for cleaning, rinsing, and storing contact lenses.
- Hydrogen Peroxide Solution: Hydrogen peroxide-based solutions provide thorough cleaning and disinfection. Always follow the instructions carefully and neutralize the solution before inserting the lenses.
In summary, water is not a safe substitute for contact lens solution. Always use an approved solution to clean, rinse, and store your contact lenses to prevent serious eye infections and maintain optimal eye health.
