Abstract
An automatic eyeglass cleaner is provided in accordance with the invention. A specially formulated cleaning and conditioning solution is also provided for use with the automatic cleaner. A tank in the automatic cleaner is filled with the cleaning and conditioning solution; the eyewear is folded up and clipped to the bottom of the open lid of the cleaner, then the lid is closed to lower the eyewear into the solution. The cleaning cycle starts with the push of a button and the eyewear is agitated in the solution. The cleaning cycle stops automatically after a pre-set time, the lid pops up and any excess solution is shaken off the eyewear by the cleaner leaving a thin film on the lenses. A microfiber cloth is used to give the lenses a final touch-up that helps fill in microscopic scratches.
