Attenuation of light transmission artifacts in wearable displays

A wearable display system, comprising:

• an eyepiece stack which transmits ambient light from a user's environment from a world side to a user side opposite the world side, wherein during use a user positioned on the user side views displayed images delivered by the wearable display system via the eyepiece stack which augment the user's field of view of the user's environment;
• and
• an angularly selective film arranged on the world side of the eyepiece stack, the angularly selective film comprising a passive polarization adjusting film arranged between a pair of linear polarizers,
• wherein the linear polarizers and polarization adjusting film significantly reduces transmission of visible light incident on the angularly selective film at large angles of incidence without significantly reducing transmission of light incident on the angularly selective film at small angles of incidence, wherein for a D65 source, the angularly selective film shifts a (0.33, 0.33) CIE 1931 white point less than (+/−0.02, +/−0.02) for unpolarized light with an angle of incidence between −32° and +32°.
