I guess my eyes are at the point where the pins just aren't showing up as well as they once did. I just got new glasses (wear progressive lens bifocals), so my eyes are as good as they are going to get. The problem I am experiencing is the pins seeming to blend together (using an older Trophy Ridge sight). This isn't a big problem for the 20 yard pin, but becomes an issue when I shoot from further out. I know I could use a single pin sight with an optimizer but I am worried about having enough time to range the deer, use my tape, and then fire. And I don't want to spend the money on one of the range finding sights that sound exceptionally complicated. So, I guess I am asking what might be available to me to help me differentiate the pins. I have difficulty differentiating the pins no matter what time of day it is. Any advice would be greatly appreciated.
