Title:
PROTECTIVE GLASSES
Document Type and Number:
WIPO Patent Application WO/2012/026563
Kind Code:
A1
Abstract:
The present invention provides protective glasses comprising: a brace bar (1); arms (2) attached to both ends of the brace bar (1); and a lens (3), wherein a central upper part of the lens (3) is fixedly attached to a center part of the brace bar (1), and a canopy part (8) having a shape corresponding to the face of a wearer protrudes from the peripheral edge of the lens (3). The lens is designed so as not to deform even if the wearer has a large head, and thus the gap between the canopy part and the face of the wearer does not increase. Therefore, the eyes of the wearer can be protected while ingress of matter such as pollen and dust is effectively prevented. In addition, since the angle of the optical axis does not change, images seen through the lens are not distorted.
