1. A wearable device comprising:
at least one camera;
at least one lens; and
at least one processor,
wherein the at least one processor is configured to:
identify illuminance information of an image obtained through the at least one camera,
determine a location on the at least one lens, based on the identified illuminance information, the location corresponding to the illuminance information,
determine an average illuminance of the image, based on the illuminance information corresponding to the determined location,
compare the illuminance information corresponding to the determined location with the average illuminance, and
adjust light transmittance of a part of the at least one lens, based on a result of the comparison.
