The invention relates to a functionalized laminated optical element comprising: &#x2014;An optical base element; &#x2014;A functional film structure consisting of a single layer or a multilayer structure; &#x2014;A layer of a pressure-sensitive adhesive of optical quality, placed between one surface of the optical base element and the functional film structure so as to permanently retain said functional film structure on the surface of the optical base element. Said functionalized laminated optical element maintains its integrity after typical processing of an optical article which includes wheel edging. More particularly the invention relates to the use of a specific adhesive system for improving the wheel edging resistance of functionalized laminated optical element. The functional laminated optical may be an ophthalmic lens.
