▎ 摘　　要

NOVELTY - An optical lens element comprises primary electrode, secondary electrode overlapping at least a portion of the primary electrode, and transparent, structurally-modified electroactive polymer arranged between and abutting the primary electrode and secondary electrode. The surface of structurally-modified electroactive polymer facing at least one of the primary electrode or secondary electrode is non-planar, when zero voltage is applied between the primary electrode and secondary electrode. USE - Element used in optical device for head mounted display (all claimed), active and passive optics and electroactive devices. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) optical device; (2) head mounted display (1945); and (3) manufacture of the optical element. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an augmented reality device stack based on a shell or buckled plate design. Lens-display assembly (1900) Display (1945) Structurally-modified electroactive polymer layer (1964) Lens (1970, 1990) Liquid lens (1960, 1980)
