Claim 9:
10. The optical system of claim 1, wherein the processor is further configured to:
determine whether the brightness of the first ambient light is below a third threshold value,
in accordance with a determination that the brightness of the first ambient light is below the third threshold value, adjust the first partial minor to increase a transmissivity of a second surface of the first combiner,
in accordance with a determination that the brightness of the ambient light is not below the third threshold value, forgo adjusting the first partial minor to increase the transmissivity of the second surface of the first combiner,
determine whether the brightness of the second ambient light is below a fourth threshold value,
in accordance with a determination that the brightness of the second ambient light is below the fourth threshold value, adjust the second partial mirror to increase a transmissivity of a second surface of the second combiner, and
in accordance with a determination that the brightness of the second ambient light is not below the fourth threshold value, forgo adjusting the second partial mirror to increase the transmissivity of the second surface of the second combiner.
