Abstract
A protective goggle construction consists of a goggle body and a toric lens which is snap received over the front of the goggle body. The goggle body includes a rigid frame portion, and a resilient face engaging portion. The frame portion includes rigid top, bottom and side walls which cooperate to define a goggle interior. The lens includes an optical toric front wall, and further includes top, bottom and side walls extending rearwardly from a peripheral edge of the front wall thereof. The top wall of the lens includes an upstanding ridge formed along the entire length thereof. The face engaging portion includes convex bulges in the temple engaging areas thereof. The rearwardly extending walls of the lens are slidably received over the frame walls to form the assembled goggle construction. Interengaging detent and clip structures are provided on the side walls of the frame and lens to releasably secure the lens and frame in assembled relation. Rearwardly extending ridges on the top and bottom walls of the frame portion cooperate with lens walls to define ventilation passages for providing an air flow over the inner surface of the front lens wall.
