A method comprising:
- receiving image light;
- reflecting a first portion of the image light via an angled partially reflective surface toward an eye of a user of a wearable head device;
- receiving environmental light via a combiner;
- transmitting, via the combiner, the environmental light toward the angled partially reflective surface;
- receiving, at a microlouver film, a second portion of the image light, via the angled partially reflective surface;
- and
- absorbing, via the microlouver film, the second portion of the image light,
- wherein the eye of the user and the angled partially reflective surface are on a same side of the microlouver film.
