Abstract
A protective eyewear including a brow member, two temple arm members, a front lens and two side shields. The front lens is removably attached to the brow member within a channel formed therein. The lens includes a series of projections adjacent one edge thereof and the brow member including a corresponding series of slots opening into the channel. The projections on the lens are engaged within the slots in the brow member to lock the lens within the brow channel. The side shields are attached to the corresponding temple arm members by means of at least one projecting hub which is engaged within the temple arm. The nub preferably includes a central opening. The temple arm is molded to the side shield such that the temple arm material fills the central opening and engages the hub to lock the side shield in position. The eyewear provides a removable lens and also forms a protective structure that meets the eyewear impact resistance standards.
