Goggles may have three types of ventilation: direct, indirect, or none.
Directly ventilated goggles create the possibility of a liquid or aerosol entering
through the ventilation port. To reduce and minimize the goggle lenses from
fogging, indirect vented models are preferred. The indirect models exclude the
direct passage of dust, liquids, light, or particles.

Face shields are protective devices intended to shield the wearer's face, or
portions thereof, in addition to the eyes. The face shield would be used when
handling pesticides where it is highly likely that splashing will occur. Face
shields are available with or without removable windows.

Employees should be cautioned about wearing contact lens in certain, if
not all, pesticide environments. Dusty or chemical environments may repre-
sent particular hazards to contact lens wearers. Soft contact lenses can be es-
pecially problematic. Their design makes them hydrophilic (absorb fluids);, as
a result they will also absorb chemical mists. If an employee is working in
these conditions, it is best that he or she not wear contact lenses.
Guidelines for selecting eye and face protection follow:
