1. A method comprising:
receiving light associated with a world object at an optical system;
projecting light associated with a virtual image onto a first eyepiece of the optical system, causing a portion of the light associated with the virtual image to propagate toward a user side of the optical system, wherein the optical system further comprises a second eyepiece positioned between a world side of the optical system and the first eyepiece; and
adjusting a dimmer of the optical system positioned between the first eyepiece and the second eyepiece to reduce an intensity of light associated with an artifact image impinging on the dimmer and an intensity of the light associated with the world object impinging on the dimmer;
stop projecting the light associated with the virtual image onto the first eyepiece; and
adjusting the dimmer to allow light impinging on the dimmer to substantially pass through the dimmer.
