Abstract: In one aspect, optic assemblies and waveguide fixtures comprising the same are described herein. In an exemplary embodiment, an optic assembly includes an optic housing, an optical insert positioned in the optic housing, and a waveguide optic positioned in the optical insert. The waveguide optic includes a light extraction face and at least two sets of light extraction elements provided on the light extraction face. The at least two sets of light extraction elements are disposed on opposing sides of an axis of symmetry for extracting a symmetric lighting distribution.
