Abstract
Lens structures are disclosed. The lens structures include a first lens spaced apart from a second lens and a spacer disposed therebetween comprising an extruded adhesive. Goggles utilizing the lens structures are disclosed. Methods of forming lens structures and goggles are also disclosed. The methods of forming the lens structures include providing a first lens, selectively applying adhesive to a surface of the first lens, contacting the adhesive applied to the first lens with a second lens to form a lens structure, and at least partially curing the adhesive. Lens structures so formed may be attached to a goggle frame. Programmable machines for implementing such inventive methods are also disclosed.
