Review on 💙 Portable VORDRASSIL Ultrasonic Contact Lens Cleaner Machine with USB Charger - for Disposal Soft, Colored, RGP, and OK Lenses (Blue) by Anita Fernandez

Error loading media. I fully understand that some claim that compared to ultrasound, it's just vibrations that actually contact and break down the protein on the contact lens. However, it works! Is it vibration or ultrasound penetrating the lens housings in the car I don't know. Lenses used for about 3 weeks burned wood for 3 days and cleaned them with a solution but still caused irritation. After 5 minutes of work it was like a new contact! The next morning I spent 3 minutes again. and still feel good at the end of the day. So I don't know if the ultrasound really penetrates or if it just "shakes off" the proteins, but I do notice a difference!
