A waveguide for use in a virtual reality, VR, or augmented reality, AR, device, is disclosed. The waveguide comprising an input region configured to couple light into the waveguide so that it propagates under total internal reflection (TIR) within the waveguide, and an output region comprising optical structures configured to receive image bearing light from the input region. The output region comprises a plurality of zones having different diffraction to each other, the plurality of zones comprising diffraction efficiencies so as to reduce rainbow artefacts.
