How Do Ultrasonic Contact Cleaners Work?

Ultrasonic cleaners use high-frequency sound waves (typically 40kHz+) to create microscopic bubbles in a cleaning solution. These bubbles collapse rapidly, producing a scrubbing action that removes debris, protein deposits, and bacteria from lens surfaces—without abrasive rubbing.

Unlike manual cleaning, ultrasonic technology can reach tiny grooves and imperfections where biofilm builds up, delivering a deeper clean in less time.

Do Ultrasonic Contact Cleaners Really Work?

Yes, ultrasonic contact cleaners work by using cavitation bubbles to lift dirt, proteins, and bacteria from lenses in minutes. Studies show ultrasonic cleaning can remove up to 99% of contaminants when used with a proper disinfecting solution, offering a deeper clean than manual rubbing alone.

• Removes microscopic debris invisible to the naked eye
• Reduces risk of eye infections from buildup
• Minimizes lens wear and scratches compared to manual rubbing
• Works in just 2–5 minutes

Key Benefits of Ultrasonic Lens Cleaning

For tech-savvy lens users, convenience and hygiene matter equally. Here’s why ultrasonic cleaning is gaining loyal fans:

• Superior hygiene: Removes more biofilm than rubbing.
• Time-saving: Cleans both lenses in minutes.
• Gentle on lenses: No physical friction that can cause micro-scratches.
• Travel-friendly: Compact designs fit easily in luggage.

How to Use an Ultrasonic Contact Lens Cleaner Safely

Using an ultrasonic cleaner is simple, but following the right steps ensures maximum effectiveness and safety.

1. Wash and dry your hands thoroughly.
2. Fill the cleaner tank with fresh multipurpose contact lens solution.
3. Place each lens in its designated basket or holder.
4. Activate the ultrasonic cycle (usually 2–5 minutes).
5. Rinse lenses with fresh solution before wearing.
6. Clean the device’s tank and basket after each use.

Using Ultrasonic Cleaner for Glasses

Yes—you can also use ultrasonic cleaners for glasses. The same cavitation process removes oils, smudges, and dust from lenses and frames without scratching. This is especially useful for delicate coatings on high-end eyewear.

Simply fill the tank with water (plus a drop of mild dish soap if desired), submerge the glasses, and run the cycle. Always dry with a microfiber cloth afterward.

Care Tips to Maximize Longevity

• Always use fresh, appropriate cleaning solution for contacts.
• Never run the device without liquid—it can damage the unit.
• Clean the tank weekly to prevent residue buildup.
• Store the device in a dry place when not in use.
