Cleaning glasses with ultrasound – tips and tricks for clear vision
Clean glasses are more than just a visual advantage – they ensure clear vision, greater comfort, and protect the material over the long term. Many people reach for a lens cleaning cloth in their everyday life. However, this method carries risks: scratches on the lenses or residue that impairs vision. A particularly thorough, gentle, and fast alternative is ultrasonic cleaning .
What is ultrasonic cleaning?
Ultrasonic devices use high-frequency sound waves to create microscopic cavitation bubbles in a liquid. These bubbles implode, dislodging even the finest dirt particles from lenses and frames – without rubbing or scratching.
