Abstract
A goggle includes a frame, a lens, and a roll-off system. The frame has a first lateral end and an opposing second lateral end. The frame defines a lens cavity. The lens is disposed within the lens cavity of the frame. The roll-off system includes a first canister, a second canister, and an actuator mechanism. The first canister is at least partially integrally formed with the first lateral end of the frame. The first canister defines a first interior cavity configured to store a roll of film. The second canister is at least partially integrally formed with the opposing second lateral end of the frame. The second canister defines a second interior cavity configured to receive a strip of film from the roll of film. The actuator mechanism is configured to facilitate selectively dispensing the strip of film from the first canister across the lens to the second canister.
