Inventive methods and apparatus for an optical assembly for a lighting fixture are disclosed. The optical assembly includes a lens (20A, 20B) having an interior face and an optical film (40A, 40B) provided atop the interior face of the lens. A deformable structure may be positioned adjacent the optical film (40A, 40B) and exert force on the optical film (40A, 40B), thereby compressing the optical film (40A, 40B) against the lens (20A, 20B). |
