Claim 10:
11. The optical system of claim 1, wherein the processor is further configured to:
determine a first difference between a brightness of a first portion of the image light received by a first surface of the first combiner and a brightness of the first ambient light received by a second surface of the first combiner;
adjust one or more of a reflectivity of the first surface of the first combiner and a transmissivity of the second surface of the first combiner based on the determined first difference;
determine a second difference between a brightness of a second portion of the image light received by a first surface of the second combiner and a brightness of the second ambient light received by a second surface of the first combiner; and
adjust one or more of a reflectivity of the first surface of the second combiner and a transmissivity of the second surface of the second combiner based on the determined second difference.
