The polarization filter in front of the projector blocks half of the projected light, and then split again one half for each eye, resulting in only 25% of the projected light reaching the eye.
This is compensated somewhat by the silver screen which boosts the brightness to about 35% of the original.[2] The overall effect is that of wearing a pair of slightly darkened glasses in a standard movie theater, which could be compensated for by using brighter projector lamps" (Wirki:
