You should see the dot just fine if you are properly using your red dot sight with both eyes open so the clarity of the glass is irrelevant in low-light conditions.
I actually have a couple of Primary Arms red dot sights, one of them being the MD-ADS, as well as Aimpoints so I've compared them extensively. The Primary Arms sights do have a light blue tint when looking through the optic, but it's not a hindrance for daytime use IMO, and once I got used to it it's not noticeable anymore until I switch back to one of my Aimpoints. The Aimpoints are crystal clear when looking through the optic, no tint or color distortion whatsoever, great for turning the sight off and shooting with cowitnessed iron sights.
I bought the Primary Arms MD-ADS to try out the mini red dot concept before dropping the cash on an Aimpoint Micro but I've been so impressed with the PA knock-off that I never bothered to get the real Aimpoint. I simply upgraded to the American Defense Mfg. QD mount and called it done. I cannot think of a reason why the OP would find the sight lacking for low-light home defense use, it's a great sight and I highly recommend Primary Arms to people who want a "real optic" but can't spend more than $200.
I used Aimpoints in the military and my experience with them was the same. Excellent optics in every way, outstanding battery life and ruggedness, red dots just don't get any better than that. I had some limited experience with EOTechs and they were problematic.
