Review on Efficient Pink Ultrasonic Contact Lens Cleaner Kit for Daily Care: Faster and Portable Cleaning by Ryan Harriger

It does its job of removing tear build-up from blocking gas permeable lenses, but you still have to wipe the dirt off the lens by hand and wash it . The problem is that the stainless steel case rusts at the top edge and is not sealed with water, so the saline solution can enter the device through the top seal between the plastic case and the steel case and rust inside the USB plug as well. When pouring out the solution, water seeps in. Once the water is in, the water cannot evaporate and penetrate, allowing bacteria to grow from the inside out. It also contaminated my contact lenses. It also causes dirty rust. The ingress of water has also corroded the inside of the USB port. From there, the USB charging plug rusted. I left the USB charger plug there and the rust completely shorted out the USB charger and it stopped working. I had to pry the USB core out with pliers because the rust had completely bonded the USB charging cable to the connector. roast. I even used Clear Care hydrogen peroxide to disinfect but that made the rust worse. The device must have a fill line to let the user know not to overfill the case and the device must also be hermetically sealed between the steel case. and plastic to keep the salt solution from penetrating and rusting on the steel case. When pouring out the cleaning solution, water will inevitably seep into the case no matter how careful you are if the case is not airtight. So there are design improvements to make it better. It is difficult to dry the inside and this sets the stage for bacterial infection when there is moisture inside the device. Therefore, pay attention to rust and contamination of contact lenses, even if you disinfect lenses after use to clean the lens due to cross-contamination. The problem would not exist if there was a sealed case between the case and the plastic. It's also not stainless steel if rust is visible between the plastic and steel case.
