Lens structures, goggles employing same, methods of forming same, and machine programmed for forming same

A goggle comprising:

• a frame coupled to a lens structure, the lens structure comprising:
• a first lens having a first surface;
• a second lens having a second surface, the second surface opposing and spaced apart from the first surface;
• and
• a spacer comprising an extruded adhesive disposed between the first surface and the second surface to define a chamber therebetween, the spacer having at least one aperture extending through a thickness thereof to communicate ambient pressure with the chamber.

A method of forming a lens structure comprising:

• providing a first lens having a surface including a peripheral edge;
• selectively applying adhesive to the surface of the first lens along a path so that the adhesive overlies the peripheral edge of the first lens;
• contacting the adhesive applied to the first lens with a second lens to form the lens structure;
• and
• at least partially curing the adhesive.
