<p>Provided are goggles in which upper and lower ends of link members (2) are respectively supported by upper and lower walls near both ends of a frame (1) with a shaft; flank ends (3a) of a lens (3) are respectively attached to the link members (2); the periphery of the lens (3) comes into contact with the periphery of the frame (1); and each of the link members (2) is rotated and controlled by operation members (4), and thus the lens (3) protrudes from the frame (1). Therefore, the goggles have excellent durability without degradation in strength of the lens, have excellent visibility without obstruction of visibility, and secure sufficient condensation protective properties without insufficient ventilation in the frame.</p> |
