I hope everyone is wearing eye protection. Ordinary prescription glasses and safety glasses will not correct astigmatism.
If the red dot is "crisp and clean" in appearance (and you are simply seeing reflections of a "crisp and clean" dot), it is not likely to be problem of astigmatism.
If you think it is astigmatism, you can verify by utilizing and gazing through small aperture of a rear peep sight.

To achieve extended battery life, the optic is engineered utilizing a low voltage diode that shines very dim; coatings on the glass are very efficient in reflecting visible light in spectrum of "red" wave length, and the glass is also tilted to facilitate this; hence the tendency for "red dot" reflection(s).
It's normal for the reflection(s) to be more noticeable in the indoor environment and when lighting is predominately behind you. Killflash ARD is NOT going to help it.
I would take the optic outside and check it in daylight. You do not necessarily have to go shooting with it. If you can't longer see the reflections or they least become hardly noticeable, then you have your answer. If the reflections are still too intense and problematic, I would suggest returning/exchanging the optic if possible, or contacting Aimpoint CS. It can be something is out of spec (e.g., glass tilt angle, diode out of position, reflective coating thickness, etc). I am confident Aimpoint CS will take good care of you.
