1. A display system, comprising:
a wearable eyewear arrangement, comprising:
a first lens assembly comprising:
a first projector to propagate first display light associated with a first image; and
a first waveguide for propagating the first image to a first eye of a user; and
a second lens assembly comprising:
a second projector to propagate second display light associated with a second image; and
a second waveguide for propagating the second image to a second eye of a user;
a bridge to couple the first lens assembly and the second lens assembly;
a disparity sensing port to receive the first display light and the second display light, wherein the first display light and the second display light are unused light; and
a processing system comprising:
a processor; and
a memory storing instructions, wherein the processing system is to:
compare the received first display light and the received second display light; and
determine, based on the comparison of the received first display light and the received second display light, at least one disparity associated with the first image and the second image.
