US 2008/0184466 A1 · Swimming and dive mask

Abstract

A water introduction mechanism (either a slit or hole) on the skirt, frame or lens of the mask, which can be opened and closed while the mask is worn to introduce water to wash out fog on the lens. The incoming water may be directed towards the lens by a tab. The water introduction mechanism can be at a variety of different locations on the mask. Where the water introduction mechanism is located on a soft part of mask, (such as the skirt), under normal circumstances, ambient water pressure will prevent the hole from opening. However, under additional external force from the user, the soft part will deform and allow water to enter the mask. The incoming water washes away the fog vapor. The user then ceases applying external force to the soft part, and the hole closes. The water introduction mechanism on the soft part of the mask can also be in the form of a “zipper” or “faucet” type device to selectively admit water into the mask interior while it is one the user's face.
