I've noticed the same thing myself, I'm 32, but far sighted w. astigmatism. Shoot right handed, left eye dominant.
I'm getting a .44 SRH soon, and will put a Bushnell Holosight atop it. Reason being: No eye relief as a scope requires, and I can shoot with BOTH eyes open, which ought to allow me to keep the gun on target for a long time, without blurring, tearing up, etc. I'll be sure to keep the group posted on how this works.
