Clear

Clear is an ultrasonic cleaner that takes the hassle out of cleaning your prescription glasses.
To start the cleaning process, simply fill the cleaner with tap water, add a few drops of the included cleaning solution, place the glasses inside, and press the power button. After the cleaning process is complete, the glasses can be removed and wiped dry with a microfiber cloth. The remaining liquid in the cleaner can then be emptied out in the sink.
Ultrasonic cleaning is a widely adopted technology used by opticians and in the jewelry industry. It has also been popularized by its use in electric toothbrushes. It is a highly effective process in which ultrasonic waves vibrate tiny particles in the water, effectively "scrubbing" any immersed object.
