A system and method for a head up display (HUD) can mitigate glare. The head up display can include a waveguide combiner including an input grating and an output grating and a glare mitigator disposed to prevent glare through the output grating from reaching an eye box. The glare mitigator can be a shade, a diffuser, a dimming element, or other device for mitigating glare. The glare mitigator can be an active or passive glare mitigator.
