Claim 0:
1. A method of manufacturing a stack of peelable lenses to have a target peel strength, the method comprising:
coating a first lens with a first adhesive coating;
heating the first adhesive coating to evaporate at least some solvent of the first adhesive coating and to initiate curing of the first adhesive coating;
after said heating the first adhesive coating, exposing the first adhesive coating to ultraviolet light to continue curing of the first adhesive coating;
after said exposing the first adhesive coating to ultraviolet light, laminating a second lens onto a surface of the first adhesive coating to produce a stack of lenses;
coating the second lens with a second adhesive coating;
heating the second adhesive coating to evaporate at least some solvent of the second adhesive coating and to initiate curing of the second adhesive coating;
after said heating the second adhesive coating, exposing the second adhesive coating to ultraviolet light to continue curing of the second adhesive coating, wherein parameters of the heating and the exposing of the first and second adhesive coatings are selected such that the first and second adhesive coatings are only partially cured to result in a peel strength of the stack that is less than the target peel strength;
after said exposing the second adhesive coating to ultraviolet light, laminating a third lens onto a surface of the second adhesive coating to add the third lens to the stack of lenses; and,
after said laminating the third lens onto the surface of the second adhesive coating, exposing the stack of lenses to an electron beam to sterilize the stack of lenses and to continue curing of the first adhesive coating and the second adhesive coating.
