Stumpsitter,
I wear glasses and am over 50. That said, my eyes correct to better than 20-20 with the glasses I wear, and I have good night vision. I have several rifles with peep sights and two with open iron sights. For me, the open iron sights with a front bead are okay for limited low light shooting at close range (30 yards and under in the dark woods), as in the morning and evening when the deer are moving. The peep sights work great at the target range with front sights of the post or small bead type. For me, I have found peep sights in low light require that the front sight bead is very large, so large it is no good for any target shooting beyond 50 yards. So you do have options given your stated range limit. My favorite hunting sight option is a low power shotgun scope. I have such on several woods hunting rifles. These give great low light target acquisition and do not add much weight or bulk to the firearm. I stay with 2.5 to 2.75 fixed power and the small objective lens configuration. You can carry a rifle wearing one of these scopes almost as well as if it had only iron sights. I have also found these low power scopes do well on a snap shot at a running deer.
