The present invention relates to an improved tool for cleaning spectacle lenses, and more particularly to a cleaning pen containing a detergent reservoir which automatically feeds the cleaning tip with detergent.
Heretofore, those wearing spectacles, especially myopic spectacles, inevitably suffer from the following problems:
(1) Many atmospheric impurities (e.g. dust, oil dirt, vapor, etc.) often deposit on the spectacle lens. Thus, a cleaning cloth and a detergent for use in cleaning spectacle lens are always needed. The detergent for use in cleaning spectacle lenses, which may be antifoggant or antistatic agent, or the composition thereof, is used before the cleaning cloth is used. In absence of either the cleaning cloth or the detergent, the spectacle lens can not be cleaned effectively. Furthermore, when the cleaning cloth and the detergent are not available, such things as clothes, toilet paper, and handchief may be used as the substitute of the cleaning cloth. These substitutes are not only ineffective for cleaning spectacle lenses, but also may damage the same.
(2) When either of the spectacle screws becomes so loose as to fall out of the spectacle frame, a suitably sized spectacle screwdriver is needed.
Presently, it is very unconvenient to carry these particular tools simultaneously.
