Patent ID: 7039959

Claim:
A goggle comprising: at least a right single-eye lens for a right eye of a user and a left single-eye lens for a left eye of the user, each single-eye lens having a lens periphery; a frame having a lens contacting surface, the frame sized to maintain the right single-eye lens and the left single-eye lens in front of the right and left eyes, respectively, of the user; a lens-retention mechanism between the single-eye lenses and the frame that selectively retains each of the single-eye lenses in a first position relative to the frame that maintains each of the single-eye lenses in front of the respective eye of the user and permits a first level of air flow between the each of the single-eye lenses and the frame, and in a second position relative to the frame that maintains each of the single-eye lenses in front of the respective eye of the user and permits a second, substantially greater level of air flow between the single-eye lenses and the frame, wherein the second position is defined such that substantially all of the lens periphery is located significantly away from the lens contacting surface; and an adjustment mechanism between the single-eye lenses and the frame that independently moves each of the single-eye lenses relative to the frame among the positions wherein the second position is defined such that substantially all of the lens periphery is located a first, substantially constant distance away from the lens contacting surface.
