ABSTRACT:
A passive mechanism supplies moisture into a chamber formed by an eyeglass frame closely fitted over at least one eyeball and the adjacent cheek or cheeks of an eyeglass wearer. The moisture may be composed of water or any suitable evaporable eye drop fluid absorbed within a moisture absorbing member, such as cotton. A moisture pervious cover, such as a perforated cover or a fluid pervious cover is provided for the moisture-absorbing member. Moisture absorbed in the moisture absorbing member is evaporated through the cover into the chamber to increase the humidity within the chamber and counteract the discomfort and ocular damage that affects the eyeballs, particularly when the wearer is elderly. This invention replaces the previous need for frequent manual application of eye drops and provides a simple mechanism free of fluid pumping elements previously needed to supply fluid to the surface of the eyeballs. The frame may be vented to prevent fogging of lenses when the chamber becomes subject to hyper-humidity.
