An optical waveguide lens and an augmented reality device are provided. The optical waveguide lens includes at least two waveguide layers, a protective layer, and a support structure. The waveguide layers are spaced apart and located on the same side of the protective layer. The waveguide layers and the protective layer are spaced apart. The support structure is disposed between two adjacent waveguide layers and/or between an adjacent waveguide layer and the protective layer. The support structure is configured to maintain a spacing between two adjacent waveguide layers and/or between an adjacent waveguide layer and the protective layer.
