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.
