Two other things that improve what you can see in low light are:
Focus - always a compromise with fixed parallax scopes because only one distance is exactly in focus - often set to about 80 or 100m. The parallax adjustment can compensate for short sightedness ( myopia) without making the reticle blurry.
Magnification - in lower light your pupil is dilated and imperfections in your eye geometry (cornea, lens and retina) degrade your visual acuity. Higher Magnification can overcome this quite a lot. You can see more detail on 6x than on 3x. As long as you meet the rule of 7mm exit pupil.
