I have a severe astigmatism in both eyes do prefer green over red light. It's the light intensity of the color that matters and not the actual color. Having a smaller dot and less surrounding light helps. Everyone's eye is different so best to test different ones. I also noticed the star burst isn't near as bad looking through a prism scope. I really wanted to use the Vortex Venom I had because I'm left eye dominant and shot right handed. I sold it and added the Truglo Pro Series sights this year and learning to shoot left handed.
