A device and method are provided. The device comprises a reflector having variable optical power; and a waveguide display assembly optically coupled to the reflector and having a light source. The waveguide display assembly is configured to guide light from the light source to transmit in a first direction towards the reflector for a first optical path, and in a second direction towards an eye-box of the device for a second optical path. The reflector is configured to reflect the light in the first direction towards the eye-box.
