The lens blank is placed adjacent the lens block with the adhesive extending therebetween. UV light is applied to cure the adhesive. The adhesive is selected to have a suitable low dimensional change on setting so as not to impart any undue stresses on the lens blank which being capable of total adhesive failure without lens damage or leaving a residue upon application of a suitable stripping force.
