PROBLEM TO BE SOLVED: To provide a dustproof goggle, solving the problems that complete sealing for preventing scattered material from entering the eyes will cause a blur due to dermal respiration and sweating of the face of a human body in a space covered with the goggle to deteriorate visibility, and when a hole-like air vent is provided in the dustproof goggle, there is the possibility that scattered material such as sparks entering through the air vent enters the eyes. SOLUTION: In this dustproof goggle, a goggle frame part 2 is provided with the swirl-like or labyrinth-like vent hole 3, or the vent hole 3 having correlation of the face for restraining progress of scattered material by a change in angle of reflection due to repetitive reflection on the inner surface of the vent hole when scattered material remains in the vent hole 3, whereby a shape having a function of excellent air permeability and dustproof performance is formed, or the air vent contains a dehumidifying agent to add a dehumidifying function.
