High-Frequency Ultrasonic Deep Cleaning, 99.9% Sterilization and Stain Removal Without Damaging Lenses Utilizing high-frequency ultrasonic technology, it generates hundreds of millions of microscopic bubble shockwaves per second, penetrating into micron-level blind spots such as lens crevices, braces grooves, and jewelry carvings, powerfully removing grease, dust, and protein deposits. After cleaning, the water becomes noticeably cloudy, and the lenses are crystal clear like new. Pure physical cleaning does not damage the lens coating, and the sterilization rate reaches 99.9%, providing greater peace of mind for cleaning contact lens cases, braces, and other items that come into contact with the mouth. 2.
