Abstract
A diver's mask has a body having a pair of symmetrically opposed first spaces defined therein, a cover detachably engaged with the body and having a pair of symmetrically opposed second spaces defined therein and respectively corresponding to the pair of first spaces, a pair of symmetrically opposed frames each detachable with and slidable onto the cover and a pair of symmetrically opposed lenses each detachably secured between the frame and the cover. Due to the slidable relationship between each of the frames and the cover, a user is able to save time assembling and disassembling elements and that the relationship between elements are able to maintain in a watertight manner.
