PROBLEM TO BE SOLVED: To provide windproof glasses by which a user can continue spraying work of agricultural chemicals without wiping off dirt, even when the dirt adheres to the glasses, in order to solve the problem that the work is disturbed by eye-smarting when the agricultural chemicals get into eyes during the spraying work of the chemicals, and that the dirt adheres to the glasses and is not removed by wiping when the user wears windproof glasses. SOLUTION: A cartridge type film is used for the transparent part of the windproof glasses. When the dirt adheres to the glasses, the soiled part of the film is wound up and the film part extended from a cartridge is made a new transparent part, which enables a user to clearly view at all times.
