Abstract
Eye protective goggles for protecting a wearer'2 eyes from particulate matter in the air includes a goggles body and a lens support fixedly secured to the body. The lens support includes a circumferential lens fitting groove of predetermined shape and is constructed of a material that is hard and rigid relative to the goggles body. An eye protective lens including a circumferential edge having a shape corresponding to the predetermined shape of the fitting groove is removably attached to the lens support by snap-fit receipt of the circumferenital edge of the lens in the fitting groove. A method of constructing eye protective goggles is also disclosed and includes athe steps of aligning a hard rigid lens support with a relatively soft flexbile goggles body by passing a plurality of tabs of the lens support through a corresponding plurality of slots of the goggles body, and securing the tabs in position relative to the slots so that the tabs are prevented from being withdrawn therefrom. Thereafter, a removable lens may be snap-fit into a fitting groove of the lens support.
