ESSKezi Sunglasses Influx AVS Terrain Tan Goggles with Adjustable Ventilation System

I am concerned that in the open position airsoft bbs could make it through, does any one know if this could happen?

only the smoke lens does not include the clear lens?

Do these still come with both clear and tinted lenses ?

Just wanna make sure, can the fully-sealed mode stop tear gas? Thanks.
