EYEWEAR WITH VENTILATION |
摘要 |
Protective eyewear of the invention includes at least one lens and a frame securing the lens. Temples or a retention strap are provided for attaching the protective eyewear to the head of a user. The frame includes a seal member around the lens with ventilation channels formed in the seal member on its surface for contacting the face of the user. Thus, the seal member forms a substantial enclosure between the lens and the face of the user when the eyewear is worn. The ventilation channels extend into the seal member towards the lens to a depth not reaching the lens and ensure free passage of air from the enclosure to the atmosphere so that moisture condensation on the lens is reduced or eliminated.
