Claim:
A device having a frame configured to wear over a user's eyes, and an outer lens retained in said frame having a slit for said user's eyes through which said user can see, the improvement comprising: said frame is configured to place said slit in front of said user's eyes, and said frame and said lens are integrally formed of a flexible material; further comprising sealing gaskets attached to said frame that contact said user's face; whereby said frame and sealing gaskets are configured to stagnantly sealingly conform to said user's face, and to passively create a stagnantly sealed interior space in front of said user's eyes; whereby dead air in said interior space becomes a passive stagnant air barrier that creates air resistance against airborne particles from entering through said slit, traversing said interior space and contacting said user's eyes; and wherein said user can see through said slit even if said airborne particles are deposited on said outer lens.
