1. A wearable device, comprising:
a light source configured to generate image light comprising a first bandwidth of light, the first bandwidth of light centered at a first frequency, the light source comprising a color source;
a see-through display configured to present the image light to a user, the see-through display comprising a mirror configured to:
direct the image light towards an eye of the user; and
transmit environmental light, wherein:
the image light does not comprise the environmental light,
the environmental light comprises a second bandwidth centered at a second frequency, and
the second frequency differs from the first frequency by less than a threshold frequency; and
one or more filters, the one or more filters configured to apply a bandpass filter to an output of the color source to transmit the first bandwidth of light.
