ABSTRACT:
A goggle for protection against dust and impact damage to the eyes including a pliable, contoured facemask having a pair of forwardly extending cage portions each adapted to receive and fixedly support a rigid eyecup. Each eyecup, in turn, supports an impact and shatter-resistant safety lens held in place with a resilient O-ring. Sides of the eyecup are provided with openings covered with dust-filtering and impact-resistant double screening. The eyecups are readily manually insertable into and removable from cage portions of the pliable facemask and each, in turn, is adapted to selectively internally support an adapter for an auxiliary ophthalmic prescription lens.
