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of the goggles body, and securing the tabs in position relative to the slots so that the tabs are prevented from being withdrawn therefrom.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.

Composite flexible goggle with rigid lens support

A plastic frame safety spectacle of the type provided with removeable concavo-convex lenses has a variable-depth lens channel formed in the respective plastic rims, each channel being configured to complementally receive a lens periphery whereby the lenses are securely held in position within the rims yet may be removed or replaced using only manual pressure and without requiring heating or other special processing of the frame. Each lens channel is continuous around its respective rim, gradually and progressively becoming deeper as the upper portion of the rim is approached such that maximum restraining is provided for the lenses along the top rims where deformation is most likely to occur from twisting or bending of the spectacle frame. The back portion of each rim is provided with a lens-engaging support ledge to preclude removal of the lenses from the backside of the frame thereby seating the lenses against dislodging by frontal impact.
